| 摘 要： | 根据对小江流域泥石流沟谷土地荒漠化影响因子的分析和筛选,选择切割密度、土壤有机质、泥石流堆积物面积、植被盖度等8个对土地荒漠化有较大影响的因子,从地貌、土壤、植被三方面建立层次分析模型。针对土地景观生态系统的复杂性和模糊性,在建立评价指标体系的基础上,采用模糊综合评判的方法,对土地荒漠化程度进行了定量评价。 |
| 关 键 词： | 泥石流多发地区 土地荒漠化 层次分析模型 模糊综合评判 |

| Abstract: | Land desertification assessment is an issue of important theory of land desertification study.The hierarchical analysis model and assessment index system of debris flow region land desertification is firstly raised.Based on analysis of factors,loading to land desertification of the debris flow region in the Xiaojiang valley Yunnan Province,eight factors closely related to the land desertification are chosen to establish a hierarchical analysis model in terms of geomorphology,soil and vegetation.According to the evaluation criteria system land desertification degrees are determined quantitatively with fuzzy evaluation. |
| Keywords: | the debris flow activity region land desertification hierarchical analysis model fuzzy evaluation |
