基于熵值法的泰安市土地可持续利用评价

Study on the Comprehensive Assessment of Sustainable Land Use in Taian City

采用Z-score法、熵值法,选取了自然、环境、社会经济3方面30个指标,评价了泰安市土地利用可持续性。结果表明:1990～2001年土地质量综合利用状况向好的方面转变,但自然、环境、社会经济子系统之间的协调性逐年下降;Z-score标准化法、熵值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 research is to assess the sustainability of land use on the base of land use change during 1990～2001 in Taian city. The method of Z score and entropy were employed. Thirty indexes covering natural, environmental and social-economic aspects were used in the integrated assessment. The annual IQI （Integrated Quality Index ） was determined and tested to assess land use sustainabillty of Taian city. The result showed the sustainability of land use of Taian city took on up-trend during 1990～2001 and there was an indication of land quantity change towards good condition while these subsystems did not develop harmoniously. The method of Z-seore and entropy whieh were fast, simple and accurate, can be used in land use process assessment.
