| 摘 要： | 利用遥感和GIS的方法获得了流域内年降水量、年均气温、地形、土壤类型和土地覆被类型等5种评价因子数据,在GIS中通过建模及空间分析,获得了布哈河流域土壤侵蚀强度等级类型及空间分布信息。结果表明,研究区土壤侵蚀总面积是14 337km2,其中轻度侵蚀和中度侵蚀面积居多,分别占土壤侵蚀总面积的54.88%和20.51%;剧烈侵蚀面积占土壤侵蚀总面积的0.63%。 |

| Abstract: | The technologies of RS and GIS were applied to obtain the five evaluation factors including annual precipitation,annual temperature,slope,elevation,and land cover within the Buhahe basin.With spatial modeling and analysis,we obtained spatial distribution of soil erosion within the basin and classified soil erosion into different classes.The results showed that in the study area,the total area of soil erosion was 14 337 km2,of which mild and moderate erosion were dominant,accounting for 54.88% and 20.51% of the total eroded area,respectively.A small portion of the basin has experienced severe erosion,accounts for 0.63% of the total eroded area. |
