Method for performing ecological restoration of hardened river banks by mangrove forest plants
The invention discloses a method for performing ecological restoration of hardened river banks by mangrove forest plants. The method comprises the following steps: removing concrete hard banks on two sides of a river channel, and protecting the banks by adopting gabion retaining walls; driving tightly arranged pine piles into a riverbed, 2-3 m away from the banks, on the inner sides of the gabion retaining walls, and filling the area defined by the pine piles and the river banks with soil to form a first beach face; in a river section with a wider river channel cross section and a lower flow speed, forming a stepped slope according to terrains; planting true mangrove plants on the first beach face; and planting the true mangrove plants and semi-mangrove plants sequentially from the near-water side to the near-shore side. According to the method, the maximum water passing amount of the cross section is increased by removing the concrete river banks and adopting the terrain design of the gabion retaining walls and the stepped slope, and the flood discharging function is enhanced. The mangrove forest plants are planted on the two sides of the river, formation of different types of habitats such as the river, mangrove forests and semi-mangrove forests is promoted, various water pollution indexes such as ammonia nitrogen, COD (chemical oxygen demand) and the like are obviously reduced, and DO (dissolved oxygen) is obviously increased.
本发明公开了一种利用红树林植物进行硬质化河岸生态修复的方法，包括以下步骤：拆除河道两边的混凝土硬质堤岸，采用石笼挡墙进行护岸；在石笼挡墙内侧离岸2～3m距离的河床，打入紧密排列的松木桩，在松木桩与河岸围合的区域，填入土壤，形成第一滩面；在河道断面较宽、流速较慢的河段，根据地势形成阶梯式坡面；在第一滩面上种植真红树植物；由近水一侧至近岸一侧依次种植真红树植物和半红树植物，本发明通过拆除混凝土河岸，采用石笼挡墙和阶梯式坡面的地形设计，增加了断面最大过水量，增强了行洪功能。在河流两岸种植红树林植物，促进了河流、红树林、半红树林等不同类型生境的形成，各项水污染指标如氨氮、COD等明显下降，DO明显上升。
