Comparison and Analysis of Estimation Methods for Heavy Metal Pollution of Farmland Soils
EZIZ Mamattursun, HAYRAT Adila, and Xiuyun YANG
Heavy metal pollution of farmland soils is a serious environmental problem. The accurate estimation of heavy metal pollution levels of farmland soils is very crucial for sustainable agriculture. Concentrations of heavy metal elements (As, Cd, Cr, Cu, Mn, Ni, Pb, and Zn) in farmland soils at 186 sampling sites in the Ba

Research Framework for Ecosystem Vulnerability: Measurement, Prediction, and Risk Assessment
Yajun WANG, and Lifang ZHONG
The fragility of ecosystem health has become a key factor hindering the sustainable development of the ecological environment. Through a review of published research from domestic and foreign scholars, starting from the endogenous logic of studies in the field of ecosystem vulnerability (EV), this paper sorts out the l

Spatial Distribution of Surface Soil Organic Carbon Density and Related Factors along an Urbanization Gradient in Beijing
Yuhong TIAN, Fenghua LIU, and Tiantian WANG
Urban surface soil has a unique set of structures and processes that affect surface soil organic carbon density (SOCdensity) and its spatial variations. Using Beijing as a case study, and assisted by field investigations and experiments, we analyzed the spatial distribution of SOCdensity in different land use types and

Effect of Long-term Experimental Warming on the Nutritional Quality of Alpine Meadows in the Northern Tibet
Wei SUN, Shaowei LI, Yangjian ZHANG, and Gang FU
The nutritional quality of grasslands is closely related to recruitment of young and population dynamics of livestock and wild herbivores. However, the response of nutritional quality to climate warming has not been fully understood in the alpine meadow on the Tibetan Plateau, especially in the Northern Tibet. Here, we

Effects of Forest Types and Environmental Factors on Soil Microbial Biomass in a Coastal Sand Dune of Subtropical China
Wei GAO, Meimei LIN, Yongrong HUANG, Shide HUANG, Gongfu YE, and Zhiqun HUANG
Coastal sand dune ecosystems generally have infertile soil with low water-holding capacity and high salinity. However, many plant species have adapted to the harsh sand environment along the southeastern coast of China. Studying the microbial biomass in such an ecosystem can improve our understanding of the roles that

A Comparative Decomposition Analysis of the Factors Driving Energy-related Carbon Emissions from Three Typical Provinces in China: Jiangsu, Henan and Inner Mongolia
Xianzhao* LIU
An accurate understanding of the real situation of energy-related carbon emissions and the main factors driving the carbon emissions increments are crucial for China to realize its emission mitigation targets. Adopting the comparative decomposition of an extended LMDI (Log-Mean Divisia Index) approach, this study decom
