摘要:
针对苏州市农村中小河道污染日益严重的现状，采用不同生态修复技术进行水环境修复，通过分析修复后水体的水质指标及浮游生物量变化，得出不同修复技术的优缺点及其适用性。研究表明各生态修复技术能够一定程度改善水体水质，但均存在一些不足，难以满足当前河道水环境的修复需求。底泥疏浚能够改善水质指标，但水体中的浮游生物量大幅减少且恢复缓慢；生态护岸对于含氮量较高的河道修复效果较差；生态浮床对于含磷量较高的河道修复效果不佳。联合修复技术，如生态护岸/ 底泥疏浚、生态湿地/ 木桩/ 自然护坡、生态浮床/ 生态护岸能显著改善水体水质和水生态，以上研究对其他平原地区农村河道的修复具有重要的参考价值和指导作用。
Abstract:
Aiming at the increasingly serious pollution situation of rural middle and small rivers in Suzhou, different ecological restoration technologies were used to repair the water environment.By analyzing the changes of water quality index and plankton biomass after restoration, the advantages and disadvantages of different remediation technologies and their applicability were obtained.Research showed that various ecological restoration technologies could improve water quality to a certain extent, but there were still some shortcomings, which were difficult to meet the current demand for restoration of river water environment.Sediment dredging could improve the water quality index, but the amount of plankton in the water body was greatly reduced and the recovery was slow.The ecological revetment had poor effect on the river with high nitrogen content, and the ecological floating bed had poor effect on the river with high phosphorus content.Joint restoration technologies, such as ecological revetment / sediment dredging, ecological wetland / stakes / natural revetment, ecological floating bed / ecological revetment could significantly improve water quality and water ecology.The above studies had important reference value and guidance for rural ri vers restoration in other plain areas.
