贵州省耕地利用可持续性评价研究
摘要: 借助能值理论与生态足迹模型,对贵州省耕地利用可持续性进行定量分析.2014年贵州省耕地人均生态承载力为0.263 hm2/人,耕地人均生态足迹为0.331 hm2/人,出现生态赤字,说明贵州省耕地利用处于不可持续状态.从贵州省耕地利用可持续性的动态趋势来看,贵州省2007年以来,耕地生态足迹增加速度较快,生态赤字不断扩大.该文提出要从增加耕地面积,优化农业生态环境入手,保障贵州耕地利用可持续发展.

Abstract: With the aid of the energy theory and the model of ecological footprint ,quantitative analysis has been carried out in this paper on the land use sustainability in Guizhou Province .T hrough calculation ,the cultivated land per capita ecological carrying capacity in Guizhou Province is 0 .263 ha/person ,cultivated land per capita ecological footprint of 0 .331 ha/person in 2014 , incur a ecological deficit , indicating Guizhou Province cultivated land use in an unsustainable state .From the dynamic trend of cultivated land use sustainability in Guizhou Province ,the cultivated land ecological footprint increase fast ,the ecological deficit is widening since 2007 .Then ,the influence factors of land use sustainability in Guizhou Province have been analyzed in this paper and suggestions have been given for promoting the cultivated land use of the sustainable development in Guizhou Province ,such as adjusting crop planting structure ,developing characteristic agriculture according to local conditions ,raising the level of agricultural science and technol‐ogy ,optimizing the agricultural ecological environment ,and formulating and improving relevant law s and regulations ,control of cultivated land at will ,etc .
