建瓯市川石乡小流域水土流失综合治理措施研究

Study on comprehensive control measures of soil and water loss in small watershed of Chuanshi Township,Jian’ou City

水土流失综合治理是改善流域生态环境,转变经济社会发展方式的关键,以小流域为基础的综合治理是我国开展水土保持工作的根本路径。为了减少水土流失,缓解人地矛盾,建瓯市川石乡以松溪支流上埞溪小流域综合整治为突破口,按照小流域目前的水土流失现状,综合考虑生态效益、经济效益和社会效益,有机结合各项治理措施,可实现小流域的生态可持续发展。在经济技术层面对比分析河道护岸类型后,选取生态护岸、植树种草、封育治理等防治水土流失的治理措施,优化协调完善防治体系,改善生态环境,促进社会经济发展,形成了可推广应用的小流域水土流失综合治理模式。

Comprehensive control of soil and water loss is the key to improve the ecological environment of river basins and change the mode of economic and social development.Comprehensive control based on small river basins is the fundamental way to carry out soil and water conservation in our country.In order to reduce soil and water loss and alleviate the contradiction between man and land,Chuanshi Township of Jian'ou City takes the comprehensive regulation of the small watershed of the Shangdi River,a tributary of Songxi,as a breakthrough.According to the current situation of soil and water loss in the small watershed,comprehensive consideration of ecological benefits,economic benefits and social benefits,and organic combination of various treatment measures can realize the ecological sustainable development of the small watershed.After comparative analysis of three types of river bank protection at the economic and technical level,ecological bank protection,planting grass,sealing and control measures are selected to optimize and coordinate the prevention and control system,improve the ecological environment,promote social and economic development,and form a comprehensive water and soil loss control model that can be popularized and applied in small watershed.
