Multistage ecological system for preventing and controlling agricultural non-point source phosphorus loss
The invention discloses a multistage ecological system for preventing and controlling agricultural non-point source phosphorus loss. The multistage ecological system is distributed in a terrace with natural fall according to a sloping field, and comprises: a desilting and water-catching system which is distributed in the whole sloping field and comprises a flood intercepting ditch, a drainage ditch and a grit chamber; a plant fence-ecological ditch system which is distributed in the sloping terrace and comprises a plant fence and an ecological ditch; a step bank wetland which is positioned onthe sloping field at the lower part of the terrace; and a phosphorus-rich ecological embankment which is positioned at the lower part of the sloping field and above a hydro-fluctuation belt. The multistage ecological system for preventing and controlling agricultural non-point source phosphorus loss can effectively intercept and control reservoir area small watershed slope cropland agricultural non-point source phosphorus loss, reduces water and soil loss, purifies rainfall runoff, and prevents and controls eutrophication of reservoir area water bodies, especially branch water bodies of largeartificial reservoirs.
本发明公开了一种阻控农业面源磷流失的多级生态系统，由依坡地呈自然落差的梯田分布设置，包括：沉沙汇水系统，分布于整个坡地，包括截洪沟、排水沟及沉砂池；植物篱‑生态沟渠系统，分布于坡地梯田内；所述植物篱‑生态沟渠系统包括植物篱和生态沟渠；梯级坡岸湿地，位于所述梯田下部的坡地；富磷生态堤岸，位于所述坡地下部及消落带上方。本发明所述的阻控农业面源磷流失的多级生态系统能够对库区小流域坡耕地农业面源磷流失进行有效拦截和控制，减少水土流失，净化降雨径流，防控大型人工水库库区水体、特别是支流水体的富营养化。
