摘要
研究针对新沟河延伸拓浚工程中典型支沟——朝阳河开展生态修复研究。首先对朝阳河的多参数水质、沉积物理化特性及深度、浮游动植物和底栖生物等水生态环境要素进行现场调查与检测,结果显示:朝阳河水质呈富营养化状态;浮游动、植物和底栖生物调查表明生物多样性偏低;表层沉积物淤积,有机质含量偏高。随后进行生态修复的可行性分析,最后因地制宜提出截污(生态缓冲沟)、清淤、曝氧等水环境整治方案和杉木桩护岸、挺水植物种植平台等水生态修复方案。
This paper studied ecological restoration on Chaoyang river, which was a typical gully in extension and dredging project of Xingou river. First of all, this paper investigated multi-parameter water quality, physical and chemical characteristics of sediment,and water ecological environment elements（ e. g. plankton and benthos）. The results showed that Chaoyang river was eutrophic. Also,the zooplankton, phytoplankton and benthos showed a low biodiversity. The surface sediments were silted up and the organic matter content was high. Then, this paper analyzed the feasibility of ecological restoration and it proposed some measures including interception, dredging, aeration, wooden bank, water plant platform, etc. in line with local conditions.
