River ecological restoration and habitat function restoration method based on cascade reservoir dismantling
The invention discloses a riverway ecological restoration and habitat function restoration method based on cascade reservoir dismantling, and belongs to the technical field of water conservancy projects. The method comprises the following steps: step 1, silt conveying; step 2, restoring the river channel; thirdly, the sand flushing gate is rebuilt or complementarily built; and 4, adjusting the discharged flow of the cascade power station. The method comprises the following steps: starting from the whole watershed step, after silt conveying and to-be-dismantled dam dismantling are completed, restoring and restoring the ecological and habitat functions of river channels at the upstream and downstream of the to-be-dismantled dam, providing a suitable habitat for aquatic animals and plants, and reconstructing or supplementing a sand flushing gate B of a next-stage dam at the downstream of the to-be-dismantled dam so as to improve the sand adjusting and flushing capacity of the next-stage dam; and the risk of dam break of the next-stage dam is reduced, and the discharge flow of the upper-stage dam and the next-stage dam of the to-be-disassembled dam is adjusted so that the discharge flow can meet the ecological flow requirement.
本发明公开了一种基于梯级水库拆除的河道生态修复与生境功能恢复方法，属于水利工程技术领域。该方法包括以下步骤：步骤一、泥沙输送；步骤二、河道修复；步骤三、冲沙闸改建或补建；步骤四、梯级电站下泄流量调整。从流域梯级整体出发，在完成泥沙输送和待拆大坝拆除后，对待拆大坝上下游的河道生态和生境功能进行修复、恢复，为水生动植物提供适宜生境，对待拆大坝下游的下一级大坝的冲沙闸B进行改建或补建，以提高下一级大坝的调沙冲沙能力，降低下一级大坝出现溃坝的风险，对待拆大坝的上一级大坝、下一级大坝的下泄流量进行调整，使其与生态流量需求相适应。
