库滨湿地生态修复研究及其工程应用:以官厅水库国家湿地公园为例

官厅水库作为北京备用水源地和西北部生态涵养区的重要节点,近年来面临生物多样性下降、滩涂人为侵占严重、水质退化等严重问题。为整体提升官厅水库库滨湿地的环境质量,改善周边人居环境,基于库区水面高程特点进行功能区划,通过污染源治理工程、湿地生态保育工程以及湿地修复及重建三大工程,重塑官厅水库库滨湿地景观,为解决库滨湿地生态环境保护与地区经济发展之间的矛盾提供技术借鉴和参考。

Ecological Restoration of Reservoir Wetland and Its Engineering Application: A Case Study of the National Wetland Park of Guanting Reservoir

As an important reserve of water source for Beijing and ecological conservation area for the northwest Beijing,Guanting Reservoir is now facing serious problems such as biodiversity decline,mudflat encroachment,and water quality degradation.In order to improve the environmental quality of the reservoir wetland and the surrounding human settlements,functional zoning was conducted based on the water level in the reservoir area.Through the implementation of major engineering projects of pollution sources control,ecological conservation,and restoration and reconstruction,the landscape of the reservoir wetlands was reconstructed.This case study provides a technical basis for solving the contradictions between the regional economic development and the environmental protection of the reservoir wetlands.
