罗时江河口湿地生态修复研究

Study on ecological restoration of Luoshijiang estuarine wetlands

  • 摘要: 洱海作为我国第七大淡水湖,承载着保障饮用水安全的重大责任,其地位不容忽视。罗时江河口湿地位于洱海罗时江河口,充当着削减罗时江带来的农业面源污染物,守护洱海水质的最后一道防线。然而,近年来罗时江河口湿地的退化问题日益严重,表现为局部区域水系不畅、植物残体分解导致水体污染、鸟类栖息地异质性较差等现象。为解决这些问题,采取以自然恢复为主、人工修复为辅的策略,通过实施水系疏通工程、植物疏除优化工程、退化湿地修复工程以及增加鸟类栖息地异质性工程等措施,旨在提升湿地整体生物多样性,大幅改善水生态环境质量,实现人与自然的和谐共生。

     

    Abstract: Erhai Lake, as the seventh largest freshwater lake in China, bears the significant responsibility of ensuring drinking water safety, and its status cannot be ignored. The Luoshijiang estuary wetland is located at the mouth of the Luoshijiang in the Erhai Lake, serving as the last line of defense to reduce agricultural non-point source pollutants brought by the Luoshijiang and protect the water quality of the Erhai Lake. However, in recent years, the degradation problem of the wetlands at the mouth of the Luoshijiang has become increasingly serious, manifested as local water system obstruction, plant residue decomposition leading to water pollution, and poor heterogeneity of bird habitats. To address these issues, this study adopts a strategy primarily based on natural restoration and supplemented by artificial restoration. Through measures such as implementing water system dredging projects, plant removal optimization projects, degraded wetland restoration projects, and increasing bird habitat heterogeneity projects, the aim is to enhance the overall biodiversity of wetlands, significantly improve the quality of water ecological environment, and achieve harmonious coexistence between humans and nature.
