摘　　要：利用相关分析和模糊数学方法对泰安市土地利用过程进行了评价。研究中选取了自然、环境、社会经济三方面30个指标进行评价,根据各指标相关系数确定指标权重,依据隶属度曲线计算各指标的隶属度。利用各指标的隶属度和权重,采用指数和公式计算各年度的综合指标值,进而评价泰安市土地利用可持续性,并且利用农业总产值对评价结果进行验证。结果显示,泰安市土地利用可持续性在1990～2001年间呈上升趋势,说明泰安市土地质量状况在不断地改善。Based on the correlation analysis and fuzzy mathematics, the evaluation of sustainable land use in Tai'an city was studied with 30 indexes which concerned nature, environment and social economy. The weighted value of each index was calculated with the method of correlation coefficient. According to membership function curve, the subjection degree was calculated. Integrated quality index (IQI) can be achieved and tested through gross agricultural production. Finally, land use sustainability of Tai'an city was evaluated with IQI. Result shows that the sustainability of land use in Tai'an city takes on an up-trend during 1990-2001, which illustrates that the land quantity changes toward good condition.
