Abstract:

t is very important to analyze the status of the carrying capacity of land resource,to keep balance of the economic development and environment protection in the Three Gorges Reservoir Area.In this paper a simple calculation method was designed to calculate the carrying capacity of land resources,with the latest relevant data in the Three Gorges Reservoir Area.The method is based on the analysis of the development process and the detailed definition of the concept of carrying capacity of land resources,which can be divided into three stages:the population carrying capacity stage,the comprehensive carrying capacity stage and the ecological footprint stage.The carrying capacity of cultivated land,forest vegetation,and the forage were calculated and analyzed with the method.The results show that the manland relationship is inconsistent,the distribution of forest vegetation is uneven,while the forage is rich.In the end,countermeasures to improve the carrying capacity of land resource,including forest vegetating which can conserve soil and water,developing traditional industries,such as livestock cultivation,citrus planting and tourism,etc were put forward.

Key words: Three Gorges Reservoir Area, carrying capacity of land resource, sustainable development
