- Abstract:
- Based on GIS and SPSS,the Dongzhen reservoir watershed was taken as example for analyzing the relationship of land use and water and soil loss by means of Integrative Index of Soil Erosion(EI) and Principal Component Analysis(PCA).The results showed that：①the sequences of EI of land use and soil and water loss in descending were:orchard>agricultural land>unused land>rural land>pasture>forest;②the contribution rate of sequences of PCA of land use and soil and water loss in descending were the same order as the EI of land use;③both of the EI and PCA had came to a same outcome.Finally,several suggestions were advised to prevent soil and water loss in Dongzhen and that may provide scientific evidences.
