英文摘要: Abstract(#br)A river watershed is a complex ecosystem, and its spatial structure and temporal dynamics are driven by various natural factors such as soil properties and topographic features, human activities, and their interactions. In this study, we explored the characteristics of the ecosystem and environment of watershed by analyzing and modeling the relationships among socio-economic indices, heavy metal elements and landscape metrics. Landsat 8 data were used to generate a land cover classification map and to derive landscape pattern indices. Governmental finance statistics yearbook data were referred to provide socio-economic indices. Moreover, 9 samples were collected from the upstream to the downstream to obtain the values of heavy metal concentrations in the water body. Then,...
