摘要
水利工程建设往往造成大量的移民,并因此在安置区造成大量的水土流失。科学的水土流失评估不仅应包括施工建设期由于大量的土方工程造成的水土流失量,运行期安置区内由于人类生产生活活动造成的水土流失也应是主要的水土流失评估内容。文章根据土地-人口-经济的耦合作用,建立土地生态系统模型,对江西DW水利工程移民安置区可能产生的水土流失进行了全面估测,并提出了控制安置区水土流失的措施,如开发小流域综合治理模式和生态农业模式等。
Hydraulic engineering construction caused a great number of migrants, thus cause unavoidable soil erosion in the resettled areas. The scientific evaluation of soil erosion includes not only one occurs during the period of construction, but also another one caused by the normal agricultural activities and life after migrants moving into the resettlement areas. According to interaction of the land-population -economic system, a land ecosystem model was established to evaluate the soil erosion caused in a resettlement area in Jiangxi Province during DW hydraulic engineering construction. Some measures such as small river basin development and eco-agriculture model, which can control soil erosion in the resettlement areas were pointed out.
