Tidal reach preposed in-situ water ecological restoration structure and method
The invention discloses a tidal reach preposed in-situ water ecological restoration structure and method. The tidal reach preposed in-situ water ecological restoration structure comprises a bank slope, a partition wall, a wetland foundation bed filler, a first planting soil layer and a second planting soil layer, and the bank slope is excavated from an embankment top to a river shoal base; the partition wall is arranged at the embankment foot protection position at the bottom of the bank slope, drainage holes are formed in the bottom of the partition wall, a submerged plant platform is arranged on the outer side of the partition wall, and submerged plants and/or floating-leaf plants are planted on the submerged plant platform; the wetland foundation bed filler is filled between the partition wall and the bank slope; the first planting soil layer is arranged at the top of the wetland foundation bed filler, the first planting soil layer forms an emergent aquatic plant platform on the inner side of the partition wall, and emergent aquatic plants are planted on the emergent aquatic plant platform; and the second planting soil layer is backfilled to the slope top of the bank slope by the wetland foundation bed filler along the bank slope, and plants are planted in the second planting soil layer. The artificial wetland is embedded into the river bank structure, the function of the river bank zone is restored and enhanced, the method of independently occupying land is not needed, the construction of the artificial ecological river bank in-situ wetland zone can be promoted, the river bank ecological function is improved, and the river channel water quality is improved.
本发明公开了一种感潮河段前置原位水生态修复结构和方法，包括：岸坡，由堤岸顶开挖至河滩基底；隔墙，设置于岸坡底部的堤岸护脚位置，隔墙底部设有泄水孔，隔墙的外侧设有沉水植物平台，沉水植物平台种植沉水植物和/或浮叶植物；湿地基床填料，填充于隔墙和岸坡之间；第一种植土层，设置于湿地基床填料顶部，第一种植土层在隔墙的内侧形成挺水植物平台，挺水植物平台种植挺水植物；第二种植土层，由湿地基床填料沿岸坡回填至岸坡的坡顶，第二种植土层种植植物。将人工湿地嵌入河岸结构，恢复并增强河岸带功能，又不用单独征占地的做法，可促进人工生态河岸原位湿地带的建设，提升河岸生态功能及改善河道水质。
