Urban inland river in-situ ecological restoration method
The urban inland river in-situ ecological restoration method comprises the following steps that an auxiliary river channel is constructed, specifically, the auxiliary river channel is constructed beside a main river channel, and the treatment scale is 7500-8500 m < 3 >/d; gravel is placed in a river bank and river water transition zone, the wood-like piles are inserted in the gravel zone, and alfalfa is planted on the gravel zone; planting auxiliary river plants: dividing an auxiliary river into a front-section purification area and a rear-section stable area; an earth ridge is built in the front-section purification area, vallisneria spiralis is planted on the slope of the earth ridge, and domesticated bottom mud containing an adsorbent is further laid at the bottom of the earth ridge; aquatic plants are planted in the rear-section stable area; and configuring facilities: arranging an air supply pipe ring with air holes on the ridge slope. According to the method for in-situ ecological restoration of the urban inland river, the water quality index stably reaches the surface water class II standard, the water pollutant concentration and water eutrophication are effectively reduced, a self-sustaining, virtuous-cycle and vitality ecological system can be formed, and the self-purification capacity of the river is effectively improved.
本发明提出了一种城市内河原位生态修复的方法，包括以下步骤：构建辅河道：在主河道一旁构建辅河道，处理规模为7500‑8500m3/d；建立块石‑仿木桩‑植物护岸：在河岸和河水过渡带放置砾石，在砾石带插入仿木桩，在砾石带上种植苜蓿；种植辅河流植物：将辅河流分为前段净化区和后段稳定区；在前段净化区修建土埂，土埂边坡种植苦草，土埂底部还铺设含有吸附剂的驯化底泥；在后段稳定区，种植水生植物；配置设施：在土埂边坡设置带有气孔的供气管环。本发明构建的城市内河原位生态修复的方法，使水质指标稳定达到地表水Ⅱ类标准，有效降低水体污染物浓度、水体富营养化，可形成一个可自我维持、良性循环、具有生命力的生态系统，有效实现河流自净能力的提高。
