宁南山区经过多年的沟壑治理实践,总结出了一条适合本地区的水土保持工程固沟模式,即在干、支沟口建坝拦泥蓄水,支毛沟修筑小型水保拦蓄工程,沟头修建防护工程,沟坡整地,实施造林种草和封育自我修复等综合措施。水土保持工程固沟模式主要是实施水土保持综合治理工程,包括生物措施和工程措施,是以沟壑为治理对象,按照因地制宜、因水治水、因害设防的原则,绿化沟道,拦截径流,防止沟头延伸、沟底下切、沟岸扩张,以达到蓄洪减沙、变害为利、合理利用水土资源的目的,取得了显著效益,适宜在同类地区推广。
After years of gully management practices in Ningnan Mountain Area, a solid-furrow pattern for soil and water conservation projects that suits the region has been concluded. That is, The first construction of protective engineering, slope slope preparation, the implementation of afforestation and seeding grass and self-repair and other comprehensive measures. Soil and water conservation project Gully model is the implementation of comprehensive management of soil and water conservation projects, including biological measures and engineering measures, is gully as the object of governance, according to local conditions, because of water, water, fortification principle, green channel, intercept runoff, prevent Ditch extension, under the ditch cut, trench ditch expansion, in order to achieve flood storage and sediment reduction, change for the benefit of the rational use of water and soil resources, has achieved significant benefits, suitable for promotion in similar areas.
