石川河生态修复模式构建探讨

Discussion on the Construction of Shichuan River Ecological Restoration Model

摘要: 本次研究以中国陕西省富平县境内石川河作为研究对象，探讨了具有针对性的修复模式。石川河运用了水量、水质、地貌和生物群落四位一体的生态修复模式。水量上采用了上游水库补给以及“上蓄、中防、下泄”模式，同时运用了河道防渗技术。水质上采用了原位处理技术进行修复，微地形增氧技术和水生生物法。地貌上采用了河道横断面结构、河流曲直性以及护岸生态化。生物群落上采用了种植挺水植物、浮水植物和沉水植物，在流域内投放鱼苗，增加河流生物多样性和是食物链的复杂性。本次石川河修复模式的提出，为加快富平县城南部新区发展，统筹城乡和谐发展作出了积极贡献，为其他流域采取类似整治工程提供了科技支撑。

Abstract: This study focused on the Shichuan River in Fuping County, Shaanxi Province, China, and explored a targeted restoration model. The Shichuan River uses a four-in-one ecological restoration model of water volume, water quality, landforms and biomes. The water quantity adopts the upstream reservoir replenishment and the “storage, medium defense, and discharge” modes, and the river anti-seepage technology is also applied. The in situ treatment technology is used for water quality restoration, micro-topography aeration technology and aquatic biological method. The cross-sectional structure of the river, the straightness of the river and the ecological protection of the revetment are adopted in the landform. Planting of emergent plants, floating plants and submerged plants is used in the biomes to release fry in the basin, increasing river biodiversity and the complexity of the food chain. The proposed Shichuan River restoration model has made positive contributions to speeding up the development of the new district in the southern part of Fuping County and coordinating the harmonious development of urban and rural areas, and providing scientific and technological support for similar remediation projects in other river basins.
