利用彩红外航片与ＴＭ数据，分析提取土壤侵蚀的主要影响因子，采用层次分析法建立了研究区专家权重模型，确定出土壤侵蚀强度级别，继而分析了攀枝花地段的土壤侵蚀特征并提出了治理措施。
The main influencing factors of soil erosion were analyzed and extracted by using color infrared video and TM data. The analytic hierarchy process was used to establish the expert weight model in the study area to determine the soil erosion intensity level. Then the characteristics of soil erosion in Panzhihua were analyzed and put forward Measures.
