| 1 | Tillage Pedogenesis of Purple Soils in Southwestern China显示文摘Land cultivation and tillage process, and their consequent impacts on soil erosion, have been criticized as the main cause of degradation of land or soil quality. However, purple soils, classified as Regosols in FAO Taxonomy or Entisols in USDA Taxonomy, are formed from purple rocks of the Trias-Cretaceous system, have been developed or at least accelerated the development due to continual tillage operation, especially digging and ridging. The present study took micromorphological investigation on the sedimentary rocks and the soils under different operations of tillage. Results show that the purple rock of Feixiangguan Formation of the Trias system (T1f) is the easiest to physical weathering and the most fertile soil material enriched in nutrients, and it has been, therefore, mostly cultivated and intensively tilled around the year. It has the fastest soil formation rate. Soil formation rate in the cropland with conventional tillage is higher than that in the forestland and the grassland. It implies that the artificial brokenness and tillage disturbance play a great role in physical weathering and initiating soil formation processes. | HE Xiubin BAO Yuhai NAN Hongwei XIONG Donghong WANG Li LIU Yanfeng ZHAO Jingbo | 2009 | Journal of Mountain Science2009，6，2： | 10 |
| 2 | C-isotope composition and correlation of the Upper Neoproterozoic in Keping area, Xinjiang显示文摘C-isotope analysis of the carbonates in the Upper Neoproterozoic in Keping, Xinjiang indicates that the Qigebrak Formation and the Upper Sugaitbrak Formation mainly record positive C-isotope values, and a distinct positive excursion occurs in the lower part of the Qigebrak Formation. There are three negative excursions in the boundary between the Qigebrak Formation and the Cambrian, the uppermost and lowermost Upper Sugaitbrak Formation. These characters resemble those of the Upper Neoproterozoic in the Three-Gorge area, which suggests that the Upper Sugaitbrak Formation and Qigebrak Formation can be correlated with the middle and upper parts of the Doushantuo Formation and Dengying Formation, respectively. The negative excursion at the top of the Upper Sugaitbrak Formation corresponds to that at the top of the Doushantuo Formation, while the negative excursion at the bottom of the Sugaitbrak Formation can be correlated with that at the middle part of the Doushantuo Formation in the Three-Gorge area and that at the top of the Hangelchaok diamictites in the Quruqtagh area. | HE XiuBin, XU Bei & YUAN ZhiYun The Key Laboratory of Orogenic Belts and Crustal Evolution, Peking University Ministry of Education of China School of Earth and Space Sciences, Peking University, Beijing 100871, China | 2007 | Chinese Science Bulletin2007，52，4： | 7 |
| 3 | The chromosome-level Hemerocallis citrina Borani genome provides new insights into the rutin biosynthesis and the lack of colchicine显示文摘Hemerocallis citrina Borani(huang hua cai in Chinese)is an important horticultural crop whose flower buds are widely consumed as a delicious vegetable in Asia.Here we assembled a high-quality reference genome of H.citrina using single-molecule sequencing and Hi-C technologies.The genome assembly was 3.77 Gb and consisted of 3183 contigs with a contig N50 of 2.09 Mb,which were further clustered into 11 pseudochromosomes.A larger portion(3.25 Gb or 86.20%)was annotated as a repetitive content and 54,295 protein-coding genes were annotated in the genome.Genome evolution analysis showed that H.citrina experienced a recent whole-genome duplication(WGD)event at~15.73 million years ago(Mya),which was the main factor leading to many multiple copies of orthologous genes.We used this reference genome to predict 20 genes involved in the rutin biosynthesis pathway.Moreover,our metabolomics data revealed neither colchicine nor its precursors in H.citrina,challenging the long-standing belief that this alkaloid causes poisoning by the plant.The results of our disruptive research are further substantiated by our genomic finding that H.citrina does not contain any genes involved in colchicine biosynthesis.The high-quality genome lays a solid foundation for genetic research and molecular breeding of H.citrina. | Zhixing Qing Jinghong Liu Xinxin Yi Xiubin Liu Guoan Hu Jia Lao Wei He Zihui Yang Xiaoyan Zou Mengshan Sun Peng Huang Jianguo Zeng | 2021 | Horticulture Research2021，8，1： | 6 |
| 4 | ^(137)Cs Finger Printing Technique for Erosion and Sedimentation Studies显示文摘137 Cs is an artificial radionuclide with a half-life of 30.2 years,which was released into the environment as a byproduct of atmospheric testing of nuclear weapons during the period of 1950s to 1970s with a peak deposition in 1963.137 Cs fallout was strongly and rapidly adsorbed by soil particles when it deposited on the ground mostly with precipitation.Its following movements will associate with the adsorbed particles.137 Cs tracing technique has been widely used in soil erosion and sedimentation studies since 1980s.This paper introduces the basis of the technique and shows several case studies of assessment of soil erosion rates,investigation of sediment sources and dating of reservoir deposits by using the technique in the Loess Plateau and the Upper Yangtze River Basin. | LONG Yi ZHANG Xinbao WEN Anbang HE Xiubin | 2012 | Journal of Mountain Science2012，9，1： | 5 |
| 5 | Fingerprinting the sources of water-mobilized sediment threatening agricultural and water resource sustainability:Progress, challenges and prospects in China显示文摘Sediment source fingerprinting apportions the sources of sediment produced by water erosion by linking sampled sediment mixtures and landscape source materials using diagnostic and conservative fingerprints.Using this approach,the nature and location of active sediment sources across the catchment can be elucidated,generating information which is a key prerequisite for the design and implementation of catchment management strategies.The science of sediment source fingerprinting continues to attract much research globally,but to date,there have been relatively few fingerprinting studies in China.Here,there remain major challenges for the fingerprinting approach arising from the uniqueness of Chinese landscapes,including for instance,the complex land use configuration with highly fragmented or mosaic patches and the highly dynamic land use conversion rates,generating a need to test the physical basis for the discriminatory power and environmental behavior of both traditional and novel tracers.Future research is needed to investigate the applicability of tracer properties in different physiographic settings and to evaluate the potential strategic utility of the approach for supporting the improved management of soil and water sustainability.Here,the strategic availability of independent observation data for different components of catchment sediment budgets and well-maintained research infrastructure for plots,micro-catchments and drainage basins provides immediate opportunity for testing the approach and refining procedures.Such detailed testing across scales would be invaluable for promoting sediment source fingerprinting as both a scientific and management tool for informing soil and water conservation practices in China. | Qiang TANG Bojie FU Anbang WEN Xinbao ZHANG Xiubin HE Adrian LCOLLINS | 2019 | Science China Earth Sciences2019，62，12： | 4 |
| 6 | Outburst Risk of Barrier Lakes in Sichuan,China显示文摘34 barrier lakes induced by earthquake have been formed by wedged debris on the river channels after a massive earthquake happening on May 12 in Sichuan, China. Among them, the Tangjiashan Barrier Lake is the largest one. It faces very urgent risk of dam breaking when water level reaches the top and begins overflow in case of storm rainfalls and continually aftershocks, threatening already devastated cities and villages with about 1.5 million people downstream. The outburst of a similar barrier lake occurred in the Minjiang River in 1933, causing a catastrophic flood. Risk analysis indicates that not all barrier lakes are highly dangerous. Only those lakes with very high dams and water to be filled up in short period need to be dealt with immediately. | CHENG Genwei WANG Xiaodan HE Xiubin FAN Jihui FAN Jianrong | 2008 | Journal of Mountain Science2008，5，3： | 4 |
| 7 | Developing a sustainable strategy to conserve reservoir marginal landscapes显示文摘China has accelerated its pace in building dams to meet growing demands in energy consumption,as well as to alleviate air pollution resulting from fossil fuel emissions and to mitigate global climate change impacts.Large rivers in southwestern China(i.e.the Jinsha,Yalong,Dadu,Wu,Nu,Lancang and upper Yangtze rivers)have primarily been targeted as major basins for hydropower development,where cascade dams have been constructed or are proposed.Among them,the Three Gorges Dam is the world's largest hydropower | qiang tang bojie fu adrian l.collins anbang wen xiubin he yuhai bao | 2018 | National Science Review2018，5，1： | 2 |

| 9 | Planation Surfaces on the Tibet Plateau,China显示文摘A planation hypothesis is proposed to explain landform evolution of the Tibet Plateau.A denudation threshold(T),the maximum potential denudation rate for a certain type of rock,is introduced to explain the combined effects of lithology and tectonics on landform evolution.If the tectonic uplifting rate(U)is equal to or less than the threshold rate(U≤T),the tectonic uplifting and terrain denudation are in dynamic equilibrium,and landforms are in a steady state.The end product should be planation surfaces whether the original landforms are flat plains or deeply dissected mountains.If U>T,uplift and denudation are not able to reach a dynamic equilibrium state.The plateau surface is mostly underlain by soft rocks,such as the Mesozoic epimetamorphic argillites and Tertiary sedimentary rocks,while the mountain ranges comprise hard rocks,such as granite,gneiss and limestone.In soft rock regions,hills are low with a relative relief of mostly less than 100m and the slopes are gentle at a gradient of <20o.In contrast,hills can maintain steep slopes in hard rock regions.The Tibet Plateau has been under an equilibrium condition between tectonic uplifting and denudation except for the mountain ranges.The plateau might have reached the present altitudes before the Quaternary. | ZHANG Xinbao HE Xiubin WANG Yangchun LONG Yi | 2008 | Journal of Mountain Science2008，5，4： | 2 |
| 10 | Micromorphological Features of Paleo-Stagnic-Anthrosols at Archaeological Site of Sanxingdui,China显示文摘The archaeological site of the Sanxingdui may date back as far as 5,000 years ago.The typical profiles of Palaeo-Stagnic-Anthrosols near the ancient site were selected,which aimed to identify diagnostic horizons employing methodology of soil taxonomic classification and to reveal the micromorphological properties of the paleosols.Under long-term anthropogenic mellowing,the discernible differentiation between anthrostagnic epipedon and its subhorizons as well as hydragric horizon and its subhorizons occurred in Paleo-Stagnic-Anthrosols at the archaeological site of the Sanxingdui.The micromorphological properties diversified among each specific diagnostic subhorizon,e.g.,the developed microstructure in cultivated subhorizon within anthrostagnic epipedon,closely arranged particles and considerable micropores beneficial to both of water conservation and filtration in plow subhorizon within anthrostagnic epipedon,and automorphic optical-orientation clays and calcareous corrosion in hydragric horizons.The findings above of micromorphological features related with diagnostic horizons are significant for soil taxonomic classification. | HE Yurong HUANG Chengmin XU Xiangming WANG Yanqiang HE Xiubin | 2008 | Journal of Mountain Science2008，5，4： | 2 |
| 11 | Farmer's Adaptive Strategies on Land Competition between Societal Outcomes and Agroecosystem Conservation in the Purple-soiled Hilly Region,Southwestern China显示文摘The worldwide extension and intensification of farming during the last century has led to ecosystem degradation and caused a series of environmental problems.Conservation of ecosystem services in agricultural regions has been implemented by top-down government actions or initiated by resilience scientists in the developed countries,but little attention was paid in the developing countries,especially in some remote mountainous regions.The present paper presents a case study showing how local farmers obtained both maximal societal outcomes and agroecosystem conservation interests in the absence of distinct boundaries between agricultural and protected ecological areas in the densely populated purple-soiled hilly region of southwestern China.The local community(Yanting County) has developed a mosaic agricultural-forestry-fishery-stock breeding system with spatially targeted land uses,diverse agricultural productions and multiple ecological partnerships.It indicates that the local farmers have hereditarily perceived sound strategies on maximizing sustainable societal outcomes and optimizing tradeoffs among macro-market,state policy,new technological facility and ecological reinforcement. | TANG Qiang BAO Yuhai HE Xiubin ZHU Bo ZHANG Xinbao | 2012 | Journal of Mountain Science2012，9，1： | 2 |

| 14 | Soil Organic Carbon Loss under Different Slope Gradients in Loess Hilly Region显示文摘Based on field runoff plots observation and sample analysis,the effect of slope gradient on soil organic carbon loss was studied under natural rainfall conditions in loess hilly region. The results showed that with slope gradient increasing(from10° to 30°) ,the changing trend of soil erosion intensity(A) was A20°>A30°>A 15°>A10°>A25°,suggesting that slope gradient between 20° and 25° was a critical degree ranger to exist. Soil organic car-bon loss was mainly influenced by soil erosion intensity,appearing the same trend as did soil erosion intensity with increasing slope gradient. Soil erosion results in organic carbon enrichment in sediment. Average enrichment ratios of five runoff plots varied from 2.27 to 3.74,and decreased with increasing erosion intensity and slope gradient. The decrease of surface runoff and soil erosion is the key to reduce soil organic carbon loss. | JIA Songwei HE Xiubin WEI Fangqiang | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 1 |

| 17 | Effects of Land Use Change on the Ecosystem Services Value in the Dry-Hot Valley显示文摘The objective of the study reported here was to determine whether LANDSAT TM images could be used to quantify changes in land-use and ecosystem services in Yuanmou County. The sizes of six land use/land cover(LUCC) categories were estimated in Yuanmou County according to the LANDSAT TM images in the summer of 1986 and 2005. Coefficients published by Xie Gaodi and co-workers in 2003 were used to value changes in ecosystem services delivered by each land use/land cover category,and the ecosystem services sensitivity analysis was conducted to de-termine the effect of manipulating these coefficients on the estimated values. The im-portant results are summarized as followings. ① The estimated size of cultivated land,pasture land,water area and unused land decreased by 6.39%,1.35%,2.25% and 10.67% respectively between 1986 and 2005. By contrast,the estimated size of forest land and construction land increased by about 2.23% and 71.15% respectively between 1986 and 2005. ② The total ecosystem services value(EVS) of the study area in-creased from 2 142 132 609.46 yuan to 2 146 416 621.00 yuan,with the net increase of 4 284 011.54 yuan during the 20-year time period. ③ The coefficient sensitivity(CS) of the study are less than unity in all cases(CS ∧1) . This indicates that the total eco-system values estimated for the study area are relatively inelastic with respect to the ecosystem service coefficients. While this implies that our estimates are robust and the coefficient is reasonable,highly under or over valued coefficients can substantially affect the veracity of estimated changes in ecosystem service values overtime even when the CS are less than unity(CS ∧1) . | ZHOU Hongyi XIONG Donghong YANG Zhong HE Xiubin | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 1 |
