Production-Living-Ecology Nexus of Land-Use Functions in the Mountainous Areas: A Case Study of Chongqing, China

As the basis of land resource allocation and use planning, land-use functions (LUFs) are important indicators for evaluating sustainable development environments. It is essential to evaluate LUFs a specific area from perspective comprehensive functions. This paper takes 38 districts counties in Chongqing, China, as an example construct state-space model three aspects, production factors, living ecological which affect resources. The continues evaluation index system determine by entropy methods calculate spatial differentiation Chongqing. results show that value multi-functions Chongqing can be divided into levels. characterized gradual weakening main urban polarization effect strong. distribution characteristics this result caused differences traffic conditions, geographical location, quality natural economic levels, planning policies, etc. In end, proposes relative suggestions facet eco-friendly strengthen future policy guidance. Future studies continue improve study spatio-temporal effects microscopic make more accurate.
