5Effect of manganese oxide-modified biochar addition on methane production and heavy metal speciation during the anaerobic digestion of sewage sludge显示文摘Low organic matter content and high heavy metal levels severely inhibit the anaerobic digestion(AD) of sewage sludge. In this study, the effect of added manganese oxidemodified biochar composite(MBC) on methane production and heavy metal fractionation during sewage sludge AD was examined. The MBC could increase the buffering capacity,enhance the methane production and degradation of intermediate acids, buffer the pH of the culture, and stabilize the sewage sludge AD process. The application of MBC positively impacted methane production and the cumulative methane yield increased up to 121.97%,as compared with the control. The MBC addition can improve metal stabilization in the digestate. An optimum MBC dose of 2.36 g was recommended, which would produce up to 121.1 L/kg volatile solids of methane. After the AD process, even though most of the metals accumulated in the residual solids, they could be transformation from the bio-available fractions to a more stable fraction. The total organic-and sulfide-bound and residual fraction content at a 3 g dose of MBC that is 0.12 g/g dry matter were 51.06% and 35.11% higher than the control, respectively. The results indicated that the application of MBC could improve the performance of AD and promote stabilization of heavy metals in sewage sludge post the AD process.Jianhua Li Min Zhang Zhiyin Ye Changming Yang 2019Journal of Environmental Sciences2019,31,2:17
6OBSERVATION AND MODEL ANALYSES OF POSITIVE CLOUD-TO-GROUND LIGHTNING IN MESOSCALE CONVECTIVE SYSTEMS显示文摘The analyses of spatial and temporal characteristics of positive cloud-to-ground(CG)lightning for four mesoscaleconvective systems and two severe local convective systems in 1989 and 1990 show that positive CG flash rate usuallyhas two peak values.The major peak occurs during the developing stage of the storm and most of the positive CGflashes originate at the lower part of the storm.The minor occurs during the dissipative stage of the storm and most ofthe positive CG flashes originate at the upper part of the storm,especially in the region of the wind divergence in thestorm anvil.The positive CG flash rate is almost an order of magnitude larger in the developing stage than in thedissipative stage.The appearing time of the peak of negative CG flash rate is in accordance with that of the valley of pos-itive CG flash rate.The higher the intensity of the radar echo,the higher the positive CG flash rate.Most of the positive CG flashes oc-cur when the weak echo area is larger,and mostly originate in the region where the radar echo intensity is about 10dBzand in the back region of the moving storms.The spatial distribution of the positive CG flashes is much more dispersivethan that of the negative.The mesoscale analysis reveals a bipolar lightning pattern.The mean bipole--length reaches itsminimum during the mature stage of the storm and reaches the maximum during the developing stage of the storm.The vertical distribution of the charge density is calculated by a one-dimensional charging model.Then,we discussthe producing condition of the positive CG lightning and forming cause of charge structure mentioned above.Yan Muhong Guo Changming Qie Xiushu Ge Zhengmo Zhang Guangshu Lanzhou Institute of Plateau Atmospheric Physics,Academia Sinica,Lanzhou 730000 1992Acta meteorologica Sinica1992,6,4:16
7Assessing the impacts of climate variability and human activities on streamflow in the water' source area of Baiyangdian Lake显示文摘作为在北方中国平原(NCP ) 的最大的沼泽地,拜伊昂达恩·莱克在维持水平衡和 NCP 的生态的健康起一个重要作用。在过去几十年,在与气候可变性和人的活动联系的 Baiyangdian 盆的减少的流速及流水量引起了一系列水和 eco 环境的问题。在这研究,我们确定了水里的流速及流水量上的气候可变性和人的活动的影响采购拜伊昂达恩·莱克的区域,基于从 1960 ~ 2008 的上面的 Tanghe 河集水(Baiyangdian 盆的亚盆) 的 hydrologic 变化的分析。气候弹性方法和水文学建模方法被用来区分气候可变性和人的活动的效果。结果证明年度流速及流水量显著地减少了(P > 0.05 ) 在 1.7, mm/a 和一个突然的变化在一年 1980 附近被识别。quantification 结果显示气候变化说明了减少的流速及流水量的 38%40% ,当人的活动说明了 60%62% 时。因此,人的活动的效果在拜伊昂达恩·莱克的水来源区域在流速及流水量的衰落上起了一个主导的作用。把生态系统作为拜伊昂达恩·莱克的健康,我们建议最小的生态的水需求和综合分水岭管理以后应该被保证。HU Shanshan LIU Changming ZHENG Hongxing WANG Zhonggen YU Jingjie 2012Journal of Geographical Sciences2012,22,5:15
8Ammonia pollution characteristics of centralized drinking water sources in China显示文摘The characteristics of ammonia in drinking water sources in China were evaluated during 2005-2009.The spatial distribution and seasonal changes of ammonia in different types of drinking water sources of 22 provinces,5 autonomous regions and 4 municipalities were investigated.The levels of ammonia in drinking water sources follow the order of river > lake/reservoir > groundwater.The levels of ammonia concentration in river sources gradually decreased from 2005 to 2008,while no obvious change was observed in the lakes/reservoirs and groundwater drinking water sources.The proportion of the type of drinking water sources is different in different regions.In river drinking water sources,the ammonia level was varied in different regions and changed seasonally.The highest value and wide range of annual ammonia was found in South East region,while the lowest value was found in Southwest region.In lake/reservoir drinking water sources,the ammonia levels were not varied obviously in different regions.In underground drinking water sources,the ammonia levels were varied obviously in different regions due to the geological permeability and the natural features of regions.In the drinking water sources with higher ammonia levels,there are enterprises and wastewater drainages in the protected areas of the drinking water sources.Qing Fu Binghui Zheng Xingru Zhao Lijing Wang Changming Liu 2012Journal of Environmental Sciences2012,24,10:15
9Influence of ammonium and nitrate supply on growth, nitrate reductase activity and N-use efficiency in a natural hybrid pine and its parents显示文摘Selection of tree species with a high capacity to assimilate N and efficiently utilize N resources would facilitate the success of initial tree seedling establishment in infertile soils.The preference for N forms was tested using three pine species(Pinus densata,Pinus tabuliformis and Pinus yunnanensis).Pinus densata is a natural diploid hybrid between P.tabuliformis and P.yunnanensis.Methods Seedlings of three pine species were supplied with nitrate-N,ammonium-N(at two different pH regimes)or combined ammonium and nitrate as a nitrogen source in perlite culture in a controlled environment.Important Findings Seedlings of P.densata had higher total biomass and net photosynthesis when supplied with nitrate-N and ammonium nitrate than with ammonium-N.In parental species,total biomass and net photosynthesis for P.yunnanensis seedlings was higher in ammonium-N than in nitrate-N,whereas the other parental species P.tabuliformis had the highest total biomass among species for all treatments except ammonium with CaCO_(3).Most morphological traits in P.densata seedlings were intermediate between its two parental species.However,N-use efficiency and photosynthetic N-use efficiency of P.densata significantly exceeded both parents when supplied with nitrate-N and ammonium nitrate.The results suggested that the diploid hybrid tree species P.densata has a preference for nitrate and is not well adapted to ammonium-N as a sole nitrogen source regardless of the growth medium pH.Based on changes in environmental conditions,such as predicted future temperature increases in high altitude areas associated with climate change,P.densata is likely to be increasingly competitive and have wide adaptation in high altitude regions.Buqing Yao Jing Cao Changming Zhao Zed Rengel 2011Journal of Plant Ecology2011,4,4:15
10Paleoproterozoic volcanic rocks in the southern margin of the North China Craton, central China:Implications for the Columbia supercontinent显示文摘The volcanic rocks of the Xiong’er Group are situated in the southern margin of the North China Craton(NCC).Research on the Xiong er Group is important to understand the tectonic evolution of the NCC and the Columbia supercontinent during the Paleoproterozoic.In this study,to constrain the age of the Xiong’er volcanic rocks and identify its tectonic environment,we report zircon LA-ICP-MS data with Hf isotope,whole-rock major and trace element compositions and Sr-Nd-Pb-Hf isotopes of the volcanic rocks of the Xiong’er Group.The Xiong’er volcanic rocks mainly consist of basaltic andesite,andesite.dacite and rhyolite,with minor basalt.Our new sets of data combined with those from previous studies indicate that Xiong’er volcanism should have lasted from 1827 Ma to 1746 Ma as the major phase of the volcanism.These volcanics have extremely low MgO.Cr and Ni contents,are enriched in LREEs and LILEs but depleted in HFSEs(Nb,Ta,and Ti),similar to arc-related volcanic rocks.They are characterized by negative zirconεHft values of-17.4 to 8.8,whole-rock initial 87Sr/86Sr values of 0.7023 to 0.7177 andεNd(t)values of-10.9 to 6.4.and Pb isotopes(206Pb/204Pb=14.366-16.431,207Pb/204Pb=15.106-15.371,208Pb/204Pb=32.455-37.422).The available elemental and Sr-Nd-Pb-Hf isotope data suggest that the Xiong’er volcanic rocks were sourced from a mantle contaminated by continental crust.The volcanic rocks of the Xiong’er Group might have been generated by high-degree partial melting of a lithospheric mantle that was originally modified by oceanic subduction in the Archean.Thus,we suggest that the subduction-modified lithospheric mantle occurred in an extensional setting during the breakup of the Columbia supercontinent in the Late Paleoproterozoic,rather than in an arc setting.Changming Wang Xinyu He Emmanuel John M.

14Impacts of Climatic Factors on Runoff Coefficients in Source Regions of the Huanghe River显示文摘Runoff coefficients of the source regions of the Huanghe River in 1956–2000 were analyzed in this paper. In the 1990s runoff of Tangnaihai Hydrologic Station of the Huanghe River experienced a serious decrease, which had at- tracted considerable attention. Climate changes have important impact on the water resources availability. From the view of water cycling, runoff coefficients are important indexes of water resources in a particular catchment. Kalinin baseflow separation technique was improved based on the characteristics of precipitation and streamflow. After the separation of runoff coefficient (R/P), baseflow coefficient (Br/P) and direct runoff coefficient (Dr/P) were estimated. Statistic analyses were applied to assessing the impact of precipitation and temperature on runoff coefficients (including Dr/P, Br/P and R/P). The results show that in the source regions of the Huanghe River, mean annual baseflow coefficient was higher than mean annual direct runoff coefficient. Annual runoff coefficients were in direct proportion to annual pre- cipitation and in inverse proportion to annual mean temperature. The decrease of runoff coefficients in the 1990s was closely related to the decrease in precipitation and increase in temperature in the same period. Over different sub-basins of the source regions of the Huanghe River, runoff coefficients responded differently to precipitation and temperature. In the area above Jimai Hydrologic Station where annual mean temperature is –3.9oC, temperature is the main factor in- fluencing the runoff coefficients. Runoff coefficients were in inverse relation to temperature, and precipitation had nearly no impact on runoff coefficients. In subbasin between Jimai and Maqu Hydrologic Station Dr/P was mainly affected by precipitation while R/P and Br/P were both significantly influenced by precipitation and temperature. In the area be-tween Maqu and Tangnaihai hydrologic stations all the three runoff coefficients increased with the rising of annual precipitation, while direct runoff coefficient was inversely proportional to temperature. In the source regions of the Huanghe River with the increase of average annual temperature, the impacts of temperature on runoff coefficients be-come insignificant.CHEN Liqun LIU Changming LI Yanping WANG Guoqiang 2007Chinese Geographical Science2007,17,1:12
15Distributed modeling of monthly air temperatures over the rugged terrain of the Yellow River Basin显示文摘Our analyses of the monthly mean air temperature of meteorological stations show that altitude,global solar radiation and surface effective radiation have a significant impact on air temperature.We set up a physically-based empirical model for monthly air temperature simulation.Combined the proposed model with the distributed modeling results of global solar radiation and routine meteorological observation data,we also developed a method for the distributed simulation of monthly air temperatures over rugged terrain.Spatial distribution maps are generated at a resolution of 1 km×1 km for the monthly mean,the monthly mean maximum and the monthly mean minimum air temperatures for the Yellow River Basin.Analysis shows that the simulation results reflect to a considerable extent the macro and local distribution characteristics of air temperature.Cross-validation shows that the proposed model displays good stability with mean absolute bias errors of 0.19℃-0.35℃.Tests carried out on local meteorological station data and case year data show that the model has good spatial and temporal simulation capacity.The proposed model solely uses routine meteorological data and can be applied easily to other regions.ZENG Yan QIU XinFa HE YongJian SHI GuoPing LIU ChangMing 2009Science China Earth Sciences2009,52,5:11

17Centrifugal casting processes of manufacturing in situ functionally gradient composite materials of Al-19Si-5Mg alloy显示文摘Cylindrical components of in situ functionally gradient composite materials of Al-19Si-5Mg alloy were manufactured by centrifugal casting. Microstructure characteristics of the manufactured components were observed and the effects of the used process factors on these characteristics were analyzed. The results of observations shows that, in thickness, the components possess microstructures accumulating lots of Mg2Si particles and a portion of primary silicon particles in the inner layer, a little Mg2Si and primary silicon particles in the outer layer, and without any Mg2Si and primary silicon particle in the middle layer. The results of the analysis indicate that the rotation rate of centrifugal casting, mould temperature, and melt pouring temperature have evidently affected the accumulation of the second phase particles. Also, the higher the centrifugal rotation rate, mould temperature, and melt pouring temperature are, the more evident in the inner layer the degree of accumulation of Mg2Si and primary silicon particles is.XIE Yong LIU Changming ZHAI Yanbo WANG Kai LING Xuedong 2009Rare Metals2009,28,4:11

19Trend in pan evaporation and its attribution over the past 50 years in China显示文摘Trends in pan evaporation are widely relevant to the hydrological community as indicators of hydrological and climate change. Pan evaporation has been decreasing in the past few decades over many large areas with differing climates globally. This study analyzes pan evaporation data from 671 stations in China over the past 50 years in order to reveal the trends of it and the corresponding trend attribution. Mann-Kendall test shows a significant declining trend in pan evaporation for most stations, with an average decrease of 17.2 mm/10a in China as a whole, the rate of decline was the steepest in the humid region (29.7 mm/10a), and was 17.6 mm/10a and 5.5 mm/10a in the semi-humid/semi-arid region and arid region, respectively. Complete correlation coefficients of pan evaporation with 7 climate factors were computed, and decreases in diurnal temperature range (DTR), SD (sunshine duration) and wind speed were found to be the main attributing factors in the pan evaporation declines. Decrease in DTR and SD may relate to the increase of clouds and aerosol as well as the other pollutants, and decrease in wind speed to weakening of the Asian winter and summer monsoons under global climate warming.LIU Min SHEN Yanjun ZENG Yan LIU Changming 2010Journal of Geographical Sciences2010,20,4:11
20Efficacy and safety of Yinchenwuling powder for hyperlipidemia: a systematic review and Meta-analysis显示文摘OBJECTIVE:To assess the clinical effectiveness and adverse effects of Yinchenwuling powder(YCWLP)in the treatment of hyperlipidemia using Meta-analysis.METHODS:Seven electronic databases were searched for randomized controlled trials designed to evaluate the clinical effectiveness of YCWLP for hyperlipidemia published in any language prior to February 2015.Two reviewers independently identified articles,extracted data,assessed quality,and cross-checked the results.Revman 5.3 was used to analyze the data.RESULTS:Only five randomized controlled trials with poor methodology were included in the analy-sis.The five trials compared YCWLP with conventional lipid-lowering drugs.Meta-analysis indicated that YCWLP was more effective at the levels of total cholesterol and triglycerides,while increasing the level of high-density lipoprotein cholesterol without serious adverse effects.However,it was not more effective than lipid-lowering drugs in reducing low-density lipoprotein cholesterol and improving hemorheology.CONCLUSION:YCWLP appeared to improve lipid levels.However,given the high risk of bias among the trials,we could not conclude that YCWLP was beneficial to patients with hyperlipidemia.More rigorous trials are required to provide stronger evidence for the conclusion.Yao Haiqiang Zhang Zengliang Wang Ji Zuo Jiacheng Chen Yu Zhu Libing Li Xiaoke Yang Zheng Wang Zisong Sun Ranran Xu Xuanxuan Li Changming Wu Yanling Li Lingru Wang Qi 2016Journal of Traditional Chinese Medicine2016,36,2:11
