Study on Evaluation of Rational Land-Use Based on EES Model of Supply and Demand Equilibrium

Abstract

The function value of land ecological services is underestimated, which leads to over-exploitation. There is an urgent need to establish a comprehensive evaluation model that can reflect the real cost of land-use projects. In this paper, we establish an EES model based on the equilibrium of supply and demand under the fixed supply of natural resources. In this model, the target value is mainly composed of ecological value EC_1 and economic value EC_2 of land ecosystem services. Subjective value is affected by different social preferences, the relationship between human development index and social value SC is established through the Pearl Growth Model, and the share of subjective value in total land value under different levels of social development is calculated. Finally, according to the utility value theory, the land scarcity index SI is introduced to reflect the relationship between land demand and land stock of land-use projects in the region and shows that the land price per unit area of different scales is different.
