Multi-belt multifunctional protection system for river reservoir hydro-fluctuation belt

WANG XIAOFENG / LI HANG / YUAN XINGZHONG

The invention discloses a river reservoir hydro-fluctuation belt multi-belt multifunctional protection system, and belongs to the technical field of hydro-fluctuation belt protection. The river reservoir hydro-fluctuation belt multi-belt multifunctional protection system comprises an ecological protection belt, the ecological protection belt is located above the highest water level line, an ecological bank fixing belt is arranged on the downstream of the ecological protection belt, a permeable pavement layer is laid below the ecological bank fixing belt, and a composite forest belt is arranged on the downstream of the ecological bank fixing belt. A concave fishway is arranged between the composite forest zone and the ecological bank fixing zone, the composite forest zone is arranged on a forest platform, a natural vegetation recovery zone is arranged on the downstream of the composite forest zone, and a bank fixing zone is arranged between the forest platform and the natural vegetation recovery zone. By the adoption of the multi-band multifunctional protection system for the river reservoir hydro-fluctuation belt, the problem that an existing hydro-fluctuation belt ecological system is unstable can be solved, and the better effect on the reduction rate of phosphorus, phosphate and soluble phosphorus and the removal rate of nitrogen, ammonia nitrogen and nitrate nitrogen is achieved.

本发明公开了一种河库消落带多带多功能防护系统，属于消落带防护技术领域。河库消落带多带多功能防护系统包括生态防护带，生态防护带位于最高水位线之上，生态防护带的下游设置有生态固岸带，生态固岸带的下方铺设有透水铺装层，生态固岸带的下游设置有复合林泽带，复合林泽带与生态固岸带之间设置有下凹的鱼道，复合林泽带设置在林泽平台上，复合林泽带的下游设置有自然植被恢复带，林泽平台与自然植被恢复带之间设置有固岸带。本发明采用上述河库消落带多带多功能防护系统，能够解决现有的消落带生态系统不稳定的问题，对磷、磷酸盐、溶解性磷的削减率以及氮、氨氮和硝态氮的去除率具有较好的效果。
