摘要
简要介绍了五里湖的概况、主要生态环境问题和对五里湖生态环境现状及其变化过程的调查,并从水文、水质、底质等方面分析了五里湖生态重建的影响因素。在此基础上结合蠡湖新城建设规划及五里湖综合整治规划,提出了相应的生态重建对策,即通过控源、利用生境修复措施创造生态恢复条件、人工重建水生植被和湖泊生态系统管理,重建良性的湖泊水生态系统。同时,从体制和机制创新的角度出发,探讨了湖泊生态系统的管理方式和途径。
The general situation,the main eco-environmental problems,the survey of present eco-environmental situation and ecological changes process of Lake Wuli were briefly introduced.The key factors of eco-reconstruction were analyzed from the conditions of hydrology,water quality and sediment.The corresponding eco-reconstruction countermeasures were put forward with consideration of the plans of new urban area and the new bank of Lake Wuli.The countermeasures included pollution sources control,habitat rehabilitation to create the conditions for ecological restoration,optimum design for artificial restoration of aquatic vegetation and aquatic ecosystem management.At the same time the mode and the way of ecosystem management were studied from the view of creating a new system and mechanism.
