【摘要】 鉴于环境评价中存在的不确定性和模糊性,为了更加客观评价区域土壤环境质量,使土地资源得到合理规划和利用,本文将物元分析法和熵权法相结合引入土壤环境质量评价体系中,构建土壤环境质量评价的模糊物元评价模型。实例分析表明,其结果可信,为土壤环境质量评价提供了一种新的途径。更多还原

【Abstract】 In view of the existence of uncertainty and fuzziness of environmental assessment,in order to evaluate more objectively regional soil environment quality,make the land resource obtaining plan and reasonable use,the substance element analysis method and the entropy weight method were combined the soil environmental quality evaluation system,fuzzy matter element model of soil environmental quality assessment was built.Example analysis shows that,the results are reliable,and provides a new way for soil environmental quality assessment.更多还原
