1Identifying paleoflood deposits archived in Zhongba Site,the Three Gorges reservoir region of the YangtzeRiver,China显示文摘Based on the principle that the present is the key to the past , detailed analyses, such as AMS 14C dating, grain size, component and morphology of heavy minerals, micro-morphology of zircon, Rb/Sr, magnetic susceptibility and total organic carbon (TOC), were conducted to identify paleoflood sediments archived in Zhongba Site. The results indicate that the plaeoflood sediments bear great similarities with modern flood sediments in the following aspects: (1) probability cumulative curves mainly show a pattern of 3―4 segments; (2) grain-size distribution of suspended matter ranges between 3 and 10Ф; (3) the sediments are well-sorted, most of which are suspended matter (>50%); (4) the same species, quantity and morphology of heavy minerals; (5) scanning electronic microscope images show that shapes of zircon are mainly oval and nearly spheral, rounded due to long-distance transport; (6) higher Rb/Sr values (0.55―0.66)than those of sediments from cultural layers (0.03―0.26); (7) magnetic susceptibility values (133.73―433.05 10-6m3/kg) are lower than those of sediments from cultural layers (959.25―2442.44 10?6 m3/kg); (8) TOC (0.14%―0.33%) are lower than those of sediments from cultural lay-ers (1.13%―2.95%). Our results demonstrate that, except for the 1981 flood, there are at least six paleoflood events that occurred during the Qing Dynasty, the middle of Song Dy-nasty, the early Warring States (400BC―350BC), the West Zhou Dynasty (920BC―900BC), the Xia Dynasty (2070BC―1600BC), and the late Neolithic Age (3000BC―2300BC), respectively .ZHU Chen ZHENG Chaogui MA Chunmei SUN Zhibin ZHU Guangyao WANG Huilin GAO Huazhong WANG Pengling HUANG Run 2005Chinese Science Bulletin2005,50,21:28
2Recent area and ice volume change of Kangwure Glacier in the middle of Himalayas显示文摘This paper calculated and evaluated the area and ice volume changes of Kangwure Glacier in Mt.Xixiabangma,middle of Himalayas in the past 3 decades,based on the field survey of glacier boundary position by differential GPS and glacier depth by Ground Penetrating Radar(GPR),together with the topographic map and remote sense data.The studied data showed that the Kangwure Glacier has experienced significant mass deficit since the 1970s,with 34.2%of area loss,48.2%ofice volume loss and 7.5 m of average thickness decrease.This result revealed that the ice volume loss of Himalayan glaciers was more serious than expected.Analysis of meteorological data from two weather stations in the region of Mt.Xixiabangma,shows that the air temperature of this region has risen from the middle of the 20th century to the beginning of the 21st century.Significant retreat of Himalayas glacier driven by climatic warming will have a remarkable impact on hydrology and ecosystem.MA LingLong TIAN LiDe PU JianChen WANG PengLing 2010Chinese Science Bulletin2010,55,20:17

4Climate change and multi-dimensional sustainable urbanization显示文摘Global large-scale urbanization and climate change have become indisputable scientific facts yet are unresolved issues,and are a common concern for mankind.The relationship between these two topics is unclear and it is not known how to deal appropriately at the scientific level with climate change in the process of urbanization.Further exploration of the science,management and practice,are needed to achieve global and regional sustainadevelopment.This paper first considers the basic facts concerning mass urbanization and climate change and summarizes the interactions and possible mechanisms of urbanization and climate change.Urbanization leads to the heat island effect,an uneven distribution of precipitation and extreme weather,together with a local-regional-global multi-scale superposition effect,which aggravates the consequences of global climate change.The impact of climate change on urbanization is mainly manifested in aspects such as changes of energy consumption,mortality,and the spread of infectious diseases,sea level rise,extreme weather damage to infrastructure,and water shortages.This paper also briefly reviews relevant international research programs and action coalitions and puts forward an analysis framework multi-dimensional sustainable urbanization which can adapt to and mitigate climate change,from the perspective of the four key dimensions—population,land use,economy,and society.It is imperative that we strengthen the interdisciplinary activities involving the natural and social sciences,take urbanization and other human activities into consideration of the land-atmosphere system,and explore the human-land-atmosphere coupling process.The adaptation and mitigation from the perspective of human activities,as represented by urbanization,might be the most critical and realistic way to deal with climate change.CHEN Mingxing XIAN Yue WANG Pengling DING Zijin 2021Journal of Geographical Sciences2021,31,9:4
5Recent high-resolution glaciochemical record from a Dasuopu firn core of middle Himalayas显示文摘A 16.8 m firn core of middle Himalayas was recovered on the col of Dasuopu glacier in August 2006,being 7000 m above sea level.A total of 317 samples were measured for stable oxygen isotope ratios(δ18O)and major ion concentrations(Na+,NH4+,K+,Mg2+,Ca2+,Cl?,SO42?,and NO3?).The firn core dating and seasonal partitioning were carried out based on the marked seasonal variations along the stable oxygen isotopes and crustal species(Ca2+,Mg2+)profiles.The multi-parameters and high-resolution glaciochemical data set of Dasuopu firn core recorded the detailed chemical characteristics of pre-cipitation in high-elevation region,middle Himalayas,since 1991 A.D.,which mainly originated from the crustal and anthropogenic sources,while the sea-salt contribution was minor.The seasonal variability of major ion concentrations was dominated by the seasonal alternation of the prevalent air mass,at-mospheric circulation situation and precipitation regime.Linear regression analysis indicated that most of the variance in annual ionic fluxes can be explained by a linear dependence on snow accumu-lation rate.WANG PengLing YAO TanDong TIAN LiDe WU GuangJian LI Zhen YANG Wei 2008Chinese Science Bulletin2008,53,3:4
6The relationship between light intensity and nutrient uptake kinetics in six freshwater diatoms显示文摘In order to find effective measures to control diatom blooms, a better understanding of the physiological characteristics of nutrient uptake in diatoms is needed. A study of P and Si-uptake kinetics for diatom species from two light regimes was conducted at low(LL),moderate(ML) and high light intensities(HL)(2, 25 and 80 μmol photons/(m2·sec)),respectively. The results showed that P uptake of diatoms was heavily influenced by historic light regimes. P affinity changed with growth and photosynthetic activity. The lowest half saturation constant for P uptake(Km(P)) was under HL for high-light adapted diatoms while the lowest half-saturation constant for low-light adapted diatoms was observed under LL. The Si half-saturation constant(Km(Si)) increased with increasing light intensities for pennate diatoms but decreased for centric diatoms. Diatom volumes were correlated with the maximum Si uptake rates(Vm(Si)) at HL and K m(Si)at ML and HL for six diatom species. Our results imply that when we assess the development of diatom blooms we should consider light intensity and cell volume in addition to ambient Si or P concentration. The relationship between light intensity and P-uptake suggests that we can find suitable methods to control diatom blooms on the basis of reducing phytoplankton activity of P-uptake and photosynthesis simultaneously.Pengling Shi Hong Shen Wenjing Wang Wenjie Chen Ping Xie 2015Journal of Environmental Sciences2015,27,8:3
7Disturbance of light-absorbing aerosols on the albedo in a winter snowpack of Central Tibet显示文摘A field observation on the albedo of the snowpack in Central Tibet was conducted in the Nam Co region in the winter of 2011. Snow properties, including grain size and density, were measured in the field, and surface-layer snow samples (down to 5 cm) were collected. The average concentrations of black carbon and dust were 72 ppbm (close to that in the glaciers of Mt. Nyainqentanglha) and 120 ppmm, respectively. Inverse trends were found to exist between the albedo of the snowpack and light-absorbing aerosols (LAAs) as well as grain size growth. Modeling showed that black carbon, dust, and grain growth in the winter snowpack can reduce the broadband albedo by 11%, 28%, and 61%, respectively.Jing Ming Pengling Wang Shuyu Zhao Pengfei Chen 2013Journal of Environmental Sciences2013,25,8:3

9Scenario-based approach for project portfolio selection in army engineering and manufacturing development显示文摘The decisions concerning portfolio selection for army engineering and manufacturing development projects determine the benefit of those projects to the country concerned.Projects are typically selected based on ex ante estimates of future return values,which are usually difficult to specify or only generated after project launch.A scenario-based approach is presented here to address the problem of selecting a project portfolio under incomplete scenario information and interdependency constraints.In the first stage,the relevant dominance concepts of scenario analysis are studied to handle the incomplete information.Then,a scenario-based programming approach is proposed to handle the interdependencies to obtain the projects,whose return values are multi-criteria with interval data.Finally,an illustrative example of army engineering and manufacturing development shows the feasibility and advantages of the scenario-based multi-objective programming approach.Pengle Zhang Kewei Yang Yajie Dou Jiang Jiang 2016Journal of Systems Engineering and Electronics2016,27,1:2
10Seasonal transition characteristics of the westerly jet: Study based on field observations at an altitude of 6900 m on the Mt. Xixiabangma Dasuopu glacier显示文摘To better understand ultra-high-altitude climate characteristics and their changes, an automatic weather station was installed on August 4, 2005 on the Mt. Xixiabangma Dasuopu glacier (28°23.04′N, 85°43.72′E, 6900 m a.s.l.) in the middle of the Himalayas. Mountain weather conditions were observed continuously and automatically. This paper is the first to publish meteorological data for a whole year for a high-elevation region, and analyze wind direction, wind speed, air temperature, air pressure and humidity. Analysis of the observation data reveals that this region was strongly influenced by the westerly jet from October 10, 2005 to April 21, 2006 and by the Indian monsoon from May to September. The seasonal transitions of the westerly jet were characterized by changes in meteorological elements. In winter, influenced by the westerly jet, the wind speed in the study region was very high and fluctuated violently, gale days were frequent, temperature and air pressure fluctuated dramatically, the diurnal range of temperature decreased and the diurnal range of air pressure increased, relative humidity and specific humidity declined sharply, and air was dry. In summer, influenced by the Indian monsoon, the relative humidity and specific humidity were high. In addition, we analyzed reanalysis data for the location of the automatic weather station. The results confirmed that this region was strongly affected by the westerly jet from October 10, 2005 to April 21, 2006 and the observations that the seasonal transitions of the westerly jet were characterized by changes in meteorological elements.LI ShengHai YAO TanDong TIAN LiDe WANG PengLing 2011Chinese Science Bulletin2011,56,18:2
