巢湖流域湿地环境质量问题及其生态重建对策

Wetland Environmental Quality Problems of Chaohu Lake Watershed and Coping Strategies for its Ecological Reconstruction

本文通过对环巢湖流域湿地的现状调查,发现巢湖及其流域存在着水质污染、富营养化、农药残留入湖、毁林开荒、水土流失、防浪林丧失、崩岸严重、湖水封闭、水生生态环境恶化等诸多问题。提出除结合工程治理措施外,应大力营造水源涵养林、低丘冈地水土保持林、巢湖平原圩区防护林、建设环湖园林生态隔离带等生物防治措施,意在为巢湖流域水环境综合治理提供科技支撑。

An investigation into the current wetland situations of Chaohu Lake Watershed found environmental quality problems in Chaohu Lake and its watershed including water quality pollution, eutrophication, pesticide residue into the lake, deforestation and land reclamation, loss of breakwater forests, serious embankment collapse, enclosed lake water and deterioration of aquatic environment. Some biological control measures were put forward for integration with engineering control measures including vigorous promotion of water conservation forestation, hillock forestation for soil and water conservation, shelterbelt forestation in polder area of Chaohu Plain, construction of landscaping ecological barrier around the lake, with the aim of providing technological support for comprehensive water environment management in Chaohu Lake Watershed.
