城市水系生态修复中的湿地规划建设研究

Wetland's Planning and Building for Ecological Restoration in Urban Water System

  • 摘要: 生态修复是城市水系治理的重要途径和方式。城市水系生态修复包括湿地建造、植被恢复和河岸生态治理等诸多与湿地紧密相连内容。城市水系生态修复与城市湿地规划建设在目标、途径、措施和技术等方面均有着共同交集。以生态学理论为指导,在利用现有城市水系资源基础上,规划建设由城市水系生态廊道和城市绿地斑块融合构成的城市湿地网。以四川省眉山市为例,提出了针对城市水系生态修复的城市湿地规划建设方案。

     

    Abstract: Urbanization has inevitably brought the threat to the urban water ecosystem. Ecological restoration and water environment rehabilitation play the major effect in the urban water system control. The ecological restoration of urban water system has three key elements,including water quality,water quantity and aquatic ecosystems. The important restoration measures consist of wetland building,vegetation planting,riparian ecology governance,and others closely related to urban wetlands. There are some common intersections between urban water system ecological restoration and urban wetland planning,such as goals, approaches,measures and technologies. With the ecology theory as the guiding principle,an urban wetland net can be built to merge with urban water system, urban ecological corridors and green patches on the basis of the existing urban water system resources. Taking the Meishan City of Sichuan province for example,this paper proposes for the urban planning and development of the wetland ecological restoration of the urban water system.
