| 摘 要： | 选取重要水源地东圳库区为研究区,利用GIS和SPSS技术,通过不同土地利用方式的土壤侵蚀综合指数和主成分分析两种方法进行定量分析与对比研究。结果表明:①不同土地利用方式的土壤侵蚀综合指数从强到弱的顺序是园地>耕地>未利用地>居民地>草地>林地;②不同土地利用的水土流失强度主成分分析得出各相关因子贡献率从大到小的顺序为:园地>耕地>未利用地>居民地>草地>林地;③通过土壤侵蚀强度综合指数和主成分分析两种方法得出的结论基本相同。最后,通过分析结果对研究区的水土流失防治提出了建议,研究结果可为东圳库区水土流失综合治理提供理论依据。

| 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. |
