Evaluation Method of Land Resources Carrying Capacity Based on Gray Target Model: a Case of Zhangzhou City in Fujian Province

Abstract

With the rapid development of ecological civilization construction in China, the bottleneck of resources and environment, especially land resources, to social and economic development has become increasingly prominent. The government and scholars are increasingly concerned about the regional resources and environment carrying capacity, especially the comprehensive carrying capacity of land resources. This paper takes Zhangzhou City as the research area, constructing the evaluation index system of comprehensive land carrying capacity of Zhangzhou from the perspective of ecology, production and living, evaluation of land comprehensive carrying capacity in Zhangzhou City from 2004 to 2016 by Using Grey Target Model. The results show that: (1) From 2004 to 2016, the comprehensive carrying capacity of land is affected by three subsystems due to the ecological, production and living capacity of the land, and the carrying capacity level is converted from a lower level to a higher level. (2) The relationship between the three subsystems changed from ecological bearing capacity > production bearing capacity > living bearing capacity in 2004 to living bearing capacity > production bearing capacity > ecological bearing capacity in 2016, indicating that Zhangzhou's ecological bearing capacity is facing certain challenges.
