为了防止和减少三峡库区坡耕地严重的水土流失和土地退化对库区农业可持续发展带来的威胁,探求坡耕地合理开发利用和保护的途径显得十分必要.由于不同耕作模式对坡耕地水、土、肥流失的影响很大,针对三峡库区坡耕地利用现状和存在的问题,利用不同的耕作模式与坡耕地水土流失关系,详细分析了坡耕地不同耕作模式的特点与各自的适宜性,综述了不同耕作模式下坡耕地水、土、肥流失的研究方法,并对坡耕地的开发利用和保护进行了展望.

Fathering Benefit Research of Slopng Cultivated Land Erosion in Three Gorges Reservior

To prevent and reduce the threats to the sustainable development of agriculture of Three Gorge Reservoir caused by the serious soil erosion and degradation of sloping cultivated land, seeking the means of suitable utilization of sloping cultivated land is very necessary. Due to the different cultivating modes make great influence to the lost of water, soil, and fertility, aiming at the utilization status and existing problems of sloping cultivated land in Three Gorge Reservoir, the characteristics and respective adaptability of different cultivating modes are analyzed using the relation between different cultivating modes and the water and soil lost of sloping cultivated land. And the research methods of lost of water, soil, and fertility of sloping cultivated land in different cultivating modes are summarized and the perspective of the development, utilization and protection of sloping cultivated land are given as well.
