Abstract

The aim of this paper is to identify conservation priorities by a specific multicriteria evaluation method in the Yongding river basin. In this paper, vegetation cover, land-use, and slope gradient are used to assess erosion risk and trends in erosion risk are obtained by comparing the results of erosion risk between 2000 and 2006. Using this information, the priority conservation areas are graded into 6 levels. The 2 highest priority levels cover the regions with severe erosion or a substantial recent increase in erosion risk (11.82% of the study area), and are recommended as erosion control regions with appropriate conservation strategies. The middle 2 levels cover the regions with stable erosion status or slight change, needing only minor measures. The method presented is fast and straightforward, showing good potential for successful application in other areas
