(河南大学环境与规划学院,河南开封475004)摘要根据影响土地沙漠化的因素和敏感性等级之间的过渡特性,本文建立了模糊综合评判模型,并运用该模型对开封市的土地沙漠化敏感性进行了评价分区.结果表明,运用模糊数学方法可以明确评价单元沙漠化的主要影响因子以及隶属于不同敏感等级的程度等信息,评价结果更具科学性.
According to influence factor of land desertification and transition specitfic property of sensitivity grade to land desertification,this paper establishes the fuzzy comphrehensive evalution model, and applies it to sensitivity assessment to land desertification in Kaifeng city. The results reveal that this method can get information about main influence factor of land desertification and degree of membership of assessment units,and that assessment results more have sciertific quality.
