Water collection area water and soil conservation ecological restoration system
The invention provides a water collection area water and soil conservation ecological restoration system, and relates to the technical field of ecological restoration. The water collection area water and soil conservation ecological restoration system comprises a slope, a water collection ditch, vegetation, a check dam, a filtering facility, a diversion channel and a drainage ditch, wherein the slope and the water collection ditch are covered with the vegetation, and the soil water content can be increased; the check dam is built in the water collection ditch, the slope toe is stabilized, silt is intercepted and stored, and the runoff speed is decreased; and the filtering facility is arranged at the confluence position of a water collection area so as to reduce water and soil loss and purify a water body. According to the water collection area water and soil conservation ecological restoration system, rainfall runoff of the water collection area can be intercepted, the soil infiltration performance is improved, and the soil water content is increased; meanwhile, the greening vegetation coverage rate is increased, the underlying surface roughness is increased, the runoff speed is decreased, the runoff peak value is decreased, the runoff scouring capacity is weakened, the water conservation capacity is improved, and water and soil loss is reduced; and runoff non-point source pollution is relieved through the intercepting and filtering effect, the water retention, soil fixation, slow flow and purification effects are good, and the utilization rate of water resources is increased.
本发明提供了一种集水区水土保持生态修复系统，涉及生态修复技术领域。本发明提供的集水区水土保持生态修复系统包括坡、集水沟、植被、谷坊、过滤设施、分流渠和排水沟，其中坡和集水沟覆盖植被，能够提高土壤含水量；集水沟内砌筑谷坊，稳定坡脚，拦蓄泥沙，降低径流速度；过滤设施设置在集水区汇流处，以减少水土流失，净化水体。该集水区水土保持生态修复系统能够拦截集水区的降雨径流，提高土壤入渗性能，土壤含水量增加，同时绿化植被覆盖率提高，增加下垫面糙度，降低径流速度，径流峰值减小，削弱径流的冲刷能力，提高水源涵养能力，减少水土流失，且经过截滤作用减轻径流面源污染，保水固土缓流净化效果好，提高水资源的利用率。
