摘　　要：土壤质量是确保农业发展、粮食安全与生态环境可持续性的关键。应用模糊物元模型对哈尔滨地区的土壤质量进行综合评价,同时利用熵权分析法确定评价指标权重。依托所构建模型对哈尔滨地区21个土壤样本进行综合排序,取得了较好的效果。本研究可为土壤健康评价提供新的思路和方法。Soil quality plays an important role in sustainable development of agriculture, grain quantitative safety and sustainable development of environment. In this paper the fuzzy matter element mode is adopted to evaluate the soil quality of the Harbin Region, at the same time, the entropy method is used to determine the weights of evaluation indexes. The model is applied to 21 soil samples in Harbin Region, and good results are obtained. The study expands the ideas and methods of the soil environment quality.
