摘要
以长江上游典型区彭州市为例,在该区SOTER(1∶50000)数据库的支持下,选取地貌类型、坡度、植被覆盖率、土地利用、土壤类型等作为评价因子,运用专家权重模型,将研究区分为无险型、轻险型、危险型、强险型和极险型5种类型,输出了土壤侵蚀危险度评价图,并指出了各种类型的防治侵蚀的措施。
It discusses soil erosion risk assessment in the typical region of upper reaches of the Yangtse River and take Pengzhou county as a case study. Based on PXSOTER(1∶50 000),five classes:strong,intensive,medium,low and noerosion risk are divided in the area taking the landforms,slope and the type of soil etc as the assessing criteria. A soil erosion risk assessment map is outputted and the erosionpreventing measures of each class are pointed out finally.
