景观水系水质保障的规划方法研究——以奥林匹克森林公园主湖为例

景观水系水质保障的规划方法是环境规划学在景观水系的具体应用之一。与其他水环境相比，景现水系有其空间尺度小、环境容量低、水量不易平衡等特点。本研究针对景观水系的特点提出了景观水系水质保障规划的主要步骤，并阐述了各部分的关键问题。本研究以奥林匹克森林公园主湖为研究对象进行了案例分析，应用规划方法确定了规划目标，进行了水量平衡计算，识别了污染源，针对自来水补水、人工湿地净化再生水、水系循环等方法设计了一系列方案，并建立模型进行分析比较。研究结果表明，人工湿地净化再生水并进行每天10000m^3的湖水循环的方案可以保证水体水质稳定在地表水三类标准，为最优方案。

Research on Planning Method of the Landscape Water Protection-Case Study on the Olympic Park Lake

Planning method of the landscape water protection is an utilization of the planning theory on the landscape water environment.Comparing with other water environment,the landscape water is featured as small scale,low environment capacity,and difficult to maintain water balance.Aiming at these features of the landscape water,some major steps and the key issues of the planning method are discussed.A case study was conducted on the Olympic Park Lake.The study followed the planning method to clarify the planning...
