Ecological restoration system for flood discharge river channel in semi-arid region
The invention discloses a semi-arid region flood discharge river ecological restoration system, and belongs to the technical field of river ecological restoration, the semi-arid region flood discharge river ecological restoration system comprises a stepped river, a plurality of concave greenbelts and a plurality of ecological reservoirs, the plurality of concave greenbelts are distributed on the two sides of the stepped river, and the plurality of ecological reservoirs are distributed on the two sides of the stepped river; when the rainfall is large, the runoff flow velocity of rainwater is reduced through the filtering vegetation, the rainwater is hoarded in the groove, the purification vegetation preliminarily purifies the hoarded rainwater, the collected rainwater is conveyed to the ecological reservoir through the pipeline, and the rainwater is further purified by the filtering algae in the ecological reservoir; collected and purified rainwater can be discharged into the stepped river channel through the drainage pipe when no rainfall exists, water flow of the stepped river channel is supplemented, and the problem that when the rainfall amount of the river channel in the semi-arid area is small, the river channel often has no water flow, and consequently the landscape performance is poor is solved.
本发明公开了一种半干旱地区泄洪河道生态恢复系统，属于河道生态恢复技术领域，包括梯级河道、多处下凹式绿地和多处生态蓄水池，多处所述下凹式绿地分布在所述梯级河道的两侧，多处所述生态蓄水池分布在所述梯级河道的两侧；本发明通过在降雨量大时，利用过滤植被来降低雨水的径流流速，雨水囤积在沟槽内，净化植被对囤积的雨水进行初步净化，收集的雨水通过管道输送到生态蓄水池，雨水在生态蓄水池受到过滤水藻进一步得到净化，收集并净化的雨水可在无降雨时通过排水管排入梯级河道，补充梯级河道的水流，解决半干旱地区河道在降雨量少时，河道常常无水流导致景观性差的问题。
