Ecological restoration mode for side pool-center beach river channel
The invention discloses an ecological restoration mode for a side pool-center beach river channel, and particularly relates to the technical field of ecological restoration. In the ecological restoration mode, water in a side pool area is deep in static flow and high in biological diversity, and a 'collection' of nutritive salt is formed; the nutritive salt in a main river channel is precipitated and degraded after being disturbed and diffused to the side pool area; the purification capacity of the side pool area is relatively high due to the growth of vegetation and animals; and different water depths are suitable for growth of different types of vegetation, and trees and shrubs, emergent aquatic plants, floating-leaved plants and submerged plants are sequentially recovered along with increase of the water depths. According to the restoration mode, ecological restoration engineering is not carried out on an original river channel, the flood discharge capacity of the original river channel is reserved, parallel river channels are constructed on the two sides of the river channel, and the biodiversity and the water quality purification capacity of a restoration area are improved; the prefabricated river channel protection slope is laid, the river bank can be effectively reinforced, and meanwhile, more living space is provided for the river bank, and the repairing effect is improved.
本发明公开了一种“边潭‑心滩”河道生态恢复模式，具体涉及生态修复技术领域，本发明中边潭区水静流深且生物多样高，形成营养盐的“汇”，主河道内的营养盐经扰动、扩散至边潭区后得以沉淀并降解，植被及动物的生长也使得边潭区净化能力较强；不同水深适宜不同类型的植被生长，随着水深增加，依次恢复乔灌木、挺水植物、浮叶植物、沉水植物；本修复模式不在原河道上开展生态修复工程，保留原有河道的行洪能力，而是在河道两侧构造构建并行河道，增加修复区生物多样性和水质净化能力；铺设预制型河道护坡，可有效对河岸进行加固处理，同时为河道岸边提供更多的生物生存空间，提高修复效果。
