基于区域生态足迹模型的广西土地可持续利用研究

Study on Land Sustainable Use in Guangxi Based on Regional Ecological Footprint Model

引入以区域平均产量为计算标准的区域生态足迹模型,计算广西地区2004年生态足迹,定量分析研究广西土地可持续利用状况。计算结果表明,广西2004年的生态足迹赤字达到0.654954hm2/人,人类对自然资源的利用已经超过了区域内土地的承载能力。建议对区域内土地利用结构和功能做出调整,选择与建立可持续发展的土地、人口、环境组合运作模式,实现人与自然和谐、合理地进行土地利用,以及产业结构的优化调整,提高广西土地可持续利用能力。

Ecological footprint model is a tool for land sustainable use evaluation.In this paper,Regional ecological footprint model with regional average output as calculative standard is used to calculate ecological footprint and assess land sustainable use in Guangxi in 2004.The results show that the regional ecological deficit in Guangxi is 0.654954hm^2 per capita.The exploitation of natural resources by human surpasses the regional land bearing capacity.It is suggested that the land use structure and function be adjusted;the operation model of integrating land,population and environment for regional sustainable development be selected and established,realizing the human-nature harmony,reasonabe land utilization planning and layout as well as optimization adjustment of industrial structure,and improving Guangxi＇s sustainable land utilization ability.
