摘要
研究目的:通过泰安市1990～2001年的土地利用变化,评价其土地利用的可持续性。研究方法:相关分析法、模糊数学方法,选取了自然、环境、社会经济3方面30个指标进行评价,确定指标权重,计算指标隶属度。采用指数和公式计算各年度的综合指标值,评价泰安市土地利用可持续性。研究结果:泰安市土地利用可持续性在1990～2001年期间呈上升趋势,土地质量状况向好的方面转变。研究结论:相关分析法和模糊数学方法可以对土地利用过程进行评价,并且具有快速、简单、准确的特点。
The purpose of this paper is to assess sustainability of land use on the basis of land use change during 1990～2001 in Tai'an city. Method of correlation analysis and fuzzy mathematics were employed. Thirty indexes, covering natural, environmental and social-economic aspects, were used in the integrated assessment. The weight and the membership function value of each index were calculated. The annual IQI (Integrated Quality Index) was determined and tested to assess land use sustainability of Tai'an city. The results show the sustainability of land use of Tan'an city took on up trend during1990～2001, a indication of land quantity change towards good condition. Correlation analysis and fuzzy mathematics method, which are fast, simple and accurate, can be used in land use process assessment.
