荒漠化防治条件下土地利用系统多维灰色动态评估——以山西省河曲县为例

Multidimensional Grey Dynamic Evaluation of Land Use System Under Desertification Control--A Case Study in Hequ County

通过对山西省河曲县荒漠化防治效益的多维灰色动态评估,实现了静态的横向比较和动态的纵向比较。预测了不同土地利用系统的发展趋势,并划分了6种发展趋势类型:即高稳定型、低稳定型、中稳定型、上升型、下降型和不稳定型。结果表明,河曲县的荒漠化防治效益以上升趋势为主。

Using multidimensional gray dynamic evaluation, comparisons of both static change and dynamic change on desertification control efficiency were studied in Hequ County, Shanxi Province. Meanwhile, change tendencies of land use system were estimated. And six types of change trends were divided, that is, high stable type, middle stable type, low stable type, rising type, descending type, unstable type. Results showed that the desertification control efficiency mainly shows a tendency to rise in the whole county.
