The invention provides an ecological restoration method for a watershed and a comprehensive improvement technology, belonging to the technical field of ecological management of rivers. The ecological restoration method comprises the following steps: A) forming steps on river slopes on the two sides of a watershed of a river, and planting lawns and shrubs; B) planting large-crown trees and lawns on the open land of river banks; C) planting emergent plants and submerged plants in the river; and D) putting fishes in the river for culturing. According to the invention, the steps are dug on the river slopes, and the lawns and the shrubs are planted on the river slopes, so water storage and soil conservation effect is achieved by changing microtopography; the emergent plants and the submerged plants are planted to achieve water quality purification effect through absorption and degradation effects of the emergent plants and the submerged plants on pollutants; the growth and reproduction of aerobic bacteria are promoted by increasing oxygen in a water body, so the purpose of enhancing and accelerating decomposition of organic pollutants in water is achieved; and thus, the ecological environment of the watershed is treated in multiple aspects, the ecological environment of the river can be thoroughly improved, and the method is worthy of being vigorously popularized.
本发明提供一种流域生态修复方法及综合整治技术，涉及河流生态治理技术领域。该流域生态修复方法，包括以下方式：A)在河流水域两边的河坡上修成台阶并种植草坪和灌木；B)在河岸空地上种植大型树冠树木和草坪；C)在河里种植挺水性植物和沉水性植物；D)在河流内投放鱼类养殖。通过河坡上挖出台阶并种植草坪和灌木，用改变微地形的办法，起到蓄水保土的效果，种植挺水性植物和沉水性植物利用其对污染物的吸收、降解，达到水质净化的效果，增加水体中氧气的方法来促使好氧细菌的生长繁殖，以达到增强和加快分解水中有机污染物的目的，多方位的对流域的生态环境进行治理，可彻底改善河流的生态环境，值得大力推广。
