| 摘 要： | 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。

| Abstract: | 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 sustainability 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-score and entropy which were fast,simple and accurate,can be used in land use process assessment. |
