River point bar fish habitat structure and construction method thereof
The invention relates to the technical field of habitat restoration, in particular to a river point bar fish habitat structure. The structure comprises a restoration sand excavation pit formed by restoring a sand excavation pit of a abandoned sand excavation site, a permeable weir arranged on the upstream side of the restoration sand excavation pit, a bottom quality improvement area formed by improving the bottom quality of a sand excavation area of the abandoned sand excavation pit, bottom quality protection training dikes arranged on the upstream side of the bottom quality improvement area and the side close to the river center and a sand-picking submerged dike arranged on one side, close to the river center, of a river point bar. The invention also relates to a construction method of the river point bar fish habitat structure. The construction method comprises the steps of restoring the sand excavation pit of the abandoned sand excavation site to form the restoration sand excavationpit, arranging a permeable weir on the upstream side of the restoration sand excavation pit, improving the bottom quality of the sand excavation area of the abandoned sand excavation site to form thebottom quality improvement area, arranging a bottom quality protection training dikes on the upstream side of the bottom quality improvement area and one side close to the river center, and arrangingthe sand-picking submerged dike on one side, close to the river center, of the river point bar. According to the structure and the method, the abandoned sand excavation site can be repaired, and a habitat is provided for fishes.
本发明涉及生境修复技术领域，尤其涉及一种河流边滩鱼类栖息地结构，包括对废弃采砂迹地的采砂坑进行修复形成的修复采砂坑、设于修复采砂坑上游侧的透水堰、对废弃采砂迹地的采砂区进行底质改善形成的底质改善区、设于底质改善区上游侧和靠近河流中心的一侧的保底质顺堤以及设于河流边滩靠近河流中心的一侧的挑砂潜堤。还涉及一种河流边滩鱼类栖息地结构的构建方法，包括对废弃采砂迹地的采砂坑进行修复形成修复采砂坑并在其上游侧设置透水堰、对废弃采砂迹地的采砂区进行底质改善形成底质改善区并在其上游侧和靠近河流中心的一侧设置保底质顺堤以及在河流边滩靠近河流中心的一侧设置挑砂潜堤。可修复废弃采砂迹地、为鱼类提供栖息生境。
