Study on comprehensive zoning of landscape ecological risk and ecosystem service value of tourist scenic spots with high landscape value

Abstract

Based on the three phases of remote sensing images and relevant socio-economic data in Southwest China, this study integrated spatial analysis, econometric models and other methods, and took the spatio-temporal evolution as the research perspective, according to the spatial correlation of landscape ecological risk and ecological risk system service value, carried out comprehensive zoning, and discussed the characteristics and differences of socio-economic factors under different zoning. The research conclusions are as follows: (1) The service value of ecological risk system is restricted by geographical location, natural conditions and other factors, and land resources are relatively fixed in a certain period; (2) Supply services are mainly food, energy and water resources provided by the environment for human beings. The value of regulatory services is mainly reflected in the ability of the environment to provide natural gas, climate, hydrological regulation and waste treatment. The value of support services refers to that the environment provides functions such as soil conservation and biodiversity maintenance; (3) Precise regional positioning and optimize land use structure. On the basis of ensuring the basic material needs, we should plan the land use structure, promote the optimal development of the land structure, and form a situation of coordinated development of ecological risks and economic benefits.
