高安市瑞沙项目区坡耕地水土流失综合治理经验及成效

The results and experiences of the sloping farmland erosion comprehensive management in the Ruisha project area of Gaoan city

江西省作为我国南方水土流失严重的省份之一,坡耕地是水土流失的主要来源地之一.长期以来,江西省坡耕地耕作较粗放,土地产出率与劳动生产率低下,抵御干旱与洪涝等自然灾害能力较差,水土流失严重.本文以江西省高安市瑞沙项目区为例介绍了坡耕地水土流失综合治理的工程概况,探讨了该项目实施过程中的做法与经验,分析了工程实施后产生的生态、社会和经济效益,并在此基础上,针对坡耕地治理中存在的问题提出建议,以期为南方红壤区坡耕地水土流失综合治理提供参考依据.

Jiangxi is one of the provinces which caused serious soil erosion in the Southern China, and the sloping farmland plays the major role in soil and water loss. For a long time, the sloping farmland was exposed to the extensive cultivation, which caused the low land productivity and labor productivity, and heavy soil and water loss occurred for the poor capabilityin withstanding natural disasters like drought and flood. In this paper, the project overview of the sloping farmland erosion comprehensive managementwas introduced with the example of Ruisha project in Gaoan city, discussed the experience and method during the project processing, and analyzed the ecological, social and economic benefits after the project beginning. Some suggestions were proposed for better resolving the problems appeared during the sloping farmland management, and the result and experience obtained in this paper provided a reference for sloping farmland erosion comprehensive management in the red soil region of Southern China.
