喀斯特农村社区可持续发展能力对比研究—以贵州清镇市王家寨与羊昌洞为例

运用近年来较常用的生态足迹方法，对贵州清镇市王家寨、羊昌洞两个生态环境背景相似的喀斯特峰丛洼地农村社区进行可持续能力评价评价及对比分析。结果表明：王家寨生态赤字2.706hm^2／人，社区生态环境处于极高的承载负荷下，传统种植业养畜、草地超载养畜、沼气池不足是造成社区生态赤字的主要原因。羊昌洞生态环境基本处于可持续发展状态，盈余为0.401hm^2／人，生态畜牧业的发展有效提高了社区可持续发展能力。因此，在喀斯特峰丛洼地社区，发展生态农业是实现可持续发展的重要途径。

A comparative study on sttstainability of rural community development in karst area：A case study of Wangjiazhai and Yangchangdong of Qingzhen City

In this paper, with the commonly used ecological footprint a comparative study is carried out on sustainable development of Wangjiazhai and Yangchangdong which are two rural communities in karst fengcong depression with similar environmental conditions. The results show that the ecological deficit of Wangjiazai community is 2.706hm^2 per capita, which indicates that the environment of Wangjiazhai is overloading. Furthermore, livestock with traditional crop, overgrazed grassland and inadequate bio-gas pits are the most important factors to the ecological deficit of Wangjiazhai. However, because of ecological stock raising, the sustainability of Yangchangdong is improved and its surplus is 0.401hm^2 per capita. The paper proposes suggestions to the sustainable development for this kind of rural community in karst fengcong depression.
