Construction method for forming underwater forest system through ecological restoration of river channel
The invention discloses a construction method for forming an underwater forest system through ecological restoration of a river channel. According to the method, the water quality of a construction site is detected in advance, growth of subsequent submerged plants is facilitated, the submerged plants mainly adopt a fork planting method, introduction of algae-eating insects and establishment of wave dissipation facilities are combined, a good foundation is laid for water quality purification of the plants, and the water quality of the submerged plants is purified through microtopography construction, plant partitioning and planting plant variety selection. The system provides a suitable natural environment for plants, and is divided into an emergent aquatic plant area, a high-temperature-season submerged plant area and a low-temperature-season submerged plant area from shallow to deep, so that plants still survive in a water body in winter, and the system can play a role in purifying the water body in four seasons, avoid algal bloom outbreak, reduce eutrophication of the water body and improve the water quality. By selecting cold-resistant hydrilla, dwarf cold-resistant vallisneria spiralis, potamogeton pectinatus, potamogeton malabaricus, vallisneria spiralis, Setaria italica and myriophyllum verticillatum for planting, the system can purify water in autumn and winter and still has ornamental value.
本发明公开了一种河道生态修复形成水下森林系统的构建方法。本发明通过事先对施工现场水质进行检测，利于后序沉水植物的生长，通过沉水植物以叉子种植法为主，并结合食藻虫的引入以及消浪设施的建立，为植株净化水质打下良好的基础，通过微地形构建、植物分区、选取种植植株种类，为植株提供了适合的自然生环境，并由浅至深分为挺水植物区、高温季沉水植物区和低温季沉水植物区，使得在冬季水体中仍有植株存活，该系统能在四季发挥净化水体的作用，避免水华爆发，减少水体的富营养化，通过选择耐寒小黑藻、矮生耐寒苦草、龙须眼子菜、竹叶眼子菜、苦草、小茨藻和狐尾藻进行种植，使得该系统能在秋冬季净化水质的同时仍具有观赏价值。
