| Abstract: | 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. |
