黄果树区域土地资源可持续利用研究

Research on Sustainable Utilization of Land Resources in Huangguoshu Area

通过分析2001-2006年黄果树区域土地利用变化,评价其土地利用可持续性。采用相关分析等统计方法,选取土地资源、生态环境、经济社会3个层面的23个指标进行评价,确定指标权重,计算指标隶属度,并用指数法公式计算各年度的综合评分值以及以上3个层面的综合评分值,评价黄果树区域土地利用可持续性。结果表明,黄果树区域土地利用可持续性在6年期间呈上升趋势,土地质量状况向好的方面转变,按照土地资源可持续利用的评价标准主要分为2个阶段,即2004年前为土地资源的准备阶段,2004年后为可持续利用发展阶段。

This paper evaluated the sustainability of land use on the basis of land related data in Huangguoshu region from 2001 to 2006.Some methods was adopted,such as correlation analysis and fuzzy mathematics,determine target weight and calculating index be subordinate to degree by 23 indices choosing land resources,ecological environment,economy society.And the sustainability of land utilization of Huangguoshu region was appraised by the exponential method formula calculated various years＇ synthesis grading value as well as above 3 stratification plane synthesis grading value.The results showed that the sustainability of land use go up and land quality changes get the better in Huangguoshu region during 6 years.According to the evaluation criterion of sustainable utilization of land resource,it is mainly divided into two stages,namely： it is the preparatory stage of land resource before 2004,and it was developing stage of sustainable utilization after 2004.
