摘要
以广西环江县为研究区域,运用生态足迹法对环江县2015-2019年生态足迹需求和足迹供给进行计算,并对其可持续发展进行分析。结果表明:环江县2015-2019年人均生态赤字1.089 hm^(2)/人,人类活动对自然资源消耗超出其生态承载力阈值;耕地和林用地占生态足迹比重最大,林用地表现为生态盈余,耕地出现生态赤字,耕地和能源用地的供需矛盾最为突出。提出:环江县实现可持续发展,需进行土地利用功能区划,优化耕地生产模式,提高单位产能,加强生态意识,划定生态红线。
In this paper,we applied ecological footprint method to measuring the ecological footprint demand and supply to analyze sustainable development in Huanjiang,Guangxi Zhuang Autonomous Regions from^(2)015 to 2019.The results indicated that anthropogenic activities have consumed natural resources exceeds their ecological carrying capacity threshold with ecological deficit per capita of 1.089 hm^(2)/per.Wherein,forest and cropland showed an ecological surpluses and deficits respectively,both them have the largest contribution to the ecological footprint.We also found that the contradiction between supply and demand is most pronounced for cropland and energy land.To achieve sustainable development,it is necessary to carry out ecological function zoning and optimize cropland production patterns to promote production capacity,strengthen ecological awareness and draw ecological protection redline.
