隆德县渝河流域水土保持生态环境治理模式探讨

Discussion on the Eco-Environment Governance Model of Soil and Water Conservation in Yuhe River Basin of Longde County

摘要: 针对流域水土保持生态环境存在的问题，研究总结提出渝河流域水土保持生态环境治理模式：山顶灌草修复生态、涵养水源；山坡退耕还林还草，保持水土，20˚以下缓坡耕地修建高标准水平梯田，发展经济产业；河谷川台地配套节水灌溉，发展高效农业；沟道修建拦蓄工程，发展灌溉，城市段沟道加强生态护坡和沿线水景观建设，实现人水和谐。从山顶、山坡、河谷川台地、沟道4个层次形成渝河流域水土保持生态治理四道防线。

Abstract: Aiming at the problems of soil and water conservation eco-environment existing in the river basin, this research studied and put forward the governance model of soil and water conservation eco-environment in Yuhe river basin of Longde County. The shrub and grass repair the eco-enviro- nment in order to conserve the water at the top of mountain. Return farmland to forest or grass on the hillside in order to conserve the water and soil. Build the high standard terraced fields to de-velop economic industry in gently sloping farmland below 20˚. Support water-saving irrigation to develop efficient agriculture on the bench terrace. Build the retaining works to develop the irriga-tion in the gully. Strengthen the ecological slope protection and water landscape construction in the city gully, in order to realize the harmony between human and water. From the four levels of the top of the mountain, the hillside, the bench terrace and gully, four lines of defense for soil and water conservation in Yuhe river basin are formed.
