重庆三峡库区生态经济区土地承载力差异分析

Analysis of land bearing capacity difference in ecological economy area of Chongqing city in TGP reservoir area

生态环境是生产力发展的自然基础和必要条件,研究土地承载力、控制人口数量、保护生态环境,对三峡库区的生态脆弱区尤为重要。分别计算出三峡库区生态经济区内19个县区(自治县)温饱粮食安全标准下的土地承载力,并进行了对比,结果表明:这些地区土地承载力指数大多大于1,人口超载严重,影响本地区的经济社会发展。结合本区域自然经济社会背景提出了相应的解决措施和对策。

Ecological environment is the natural base and a necessary condition for productivity development.It is especial crucial to study land bearing capacity,population,population control and ecological environment protection are especial important for ecologically fragile zones in TGP reservoir areas.This paper separately calculates land bearing capacity of 19 counties(or administrative zones) in the TGP reservoir area under the adequate food and clothing standard,and carries out mutual comparison.The result shows that land bearing capacity indexes in all zones are over 1,the population overload seriously,and affects the local economic and social smooth development.At last,the corresponding solutions and countermeasures are put forward according to natural,social and economic backgrounds in TGP reservoir area.
