| 摘 要： | 土地利用直接改变土壤侵蚀的方式和强度,具有突出的侵蚀环境效应.以黑惠江流域为例,探讨了滇西高山峡谷区土地利用对土壤侵蚀的影响.研究表明,本区土地利用内部转化以林地转化最为突出,引起土壤侵蚀面积的降低或升高;各利用类型向林地的转化均有利于减少土壤侵蚀,而向耕地的转化则会增加土壤侵蚀.同时,耕地向林地、草地、水域的转化使侵蚀强度指数显著降低,而林地向耕地、草地转化,水域向其它土地利用类型的转化,均显著增加侵蚀强度指数. |
| 关 键 词： | 高山峡谷 黑惠江流域 土地利用 土壤侵蚀 侵蚀环境 |

| Abstract: | Land use changes the pattern and extent of soil erosion directly and has striking erosion-environmental effect.Heihui River is taken as an example to probe into the effect of land use on soil erosion in alpine gorges in the west Yunnan Province.It is shown through the results that an internal transformation of forest land causes increasing or dropping of erosion area.It also indicates that a transformation of all types of land use to forest land is propitious to erosion control,and generates erosion if the ... |
