基于生态足迹模型的边境城市土地可持续利用研究——以广西东兴市为例

Research on Border City's Sustainable Land Use Based on Ecological Footprint Theory

以边境城市土地可持续利用为研究对象,以生态足迹理论为指导,运用生态足迹模型,以经济社会统计数据及土地利用变更数据为依据,计算东兴市2006—2014年生态足迹及生态承载力,并分析东兴市多年生态足迹供需情况。研究期间,东兴市人均生态足迹和人均生态承载力整体呈上升的态势,人均生态足迹从3.510 3hm^2/人上升到4.6382hm^2/人,人均生态承载力从0.6021hm^2/人上升到0.6328hm^2/人,人均生态赤字从2.9082hm^2/人上升到4.0054hm^2/人。目前东兴市处于生态赤字状态,建议通过开发推广先进生产技术,节约集约利用资源,改变传统的高能耗、高污染的生产方式来减小生态赤字,实现土地可持续利用。

By using border city＇s sustainable land as the research object and ecological footprint theory as the guideline, using ecological footprint model, with social ＆ economic statistical data and the data of land use as the basis to calculate the ecological footprint and ecological carrying capacity of the city, and to further analyze the ecological footprint of supply and demand situation, the paper shows that, during the study, the ecological footprints per capita increased from 3.5130 hm2 to 4.6328 hm2 , the ecological carrying capacity per capita increased from 0.6021 hm2 to 0.6328 hm2 , the ecologi- cal deficit per capita increased from 2.9082 hm2 to 4.0054 hm2.
