摘要
为揭示水源地水质与潮汐河口水流运动、污染源及排放方式等的影响规律，明确水源地水质主要影响因素，形成潮汐河口水源地保护区的划分技术方法体系，填补潮汐河口水库型水源地保护区的划分技术方法的空白。研究以青草沙水源地为例划分水源保护区范围，对国内外饮用水水源地保护区的划分方法进行了调研。指出目前国内的饮用水水源地保护区划分技术方法在潮汐河口水域应用时存在科学性差、适用性不强等问题。研究针对河口潮汐往复流特征、水污染排放和水环境特点，提出了充分利用水库库区自净能力的划分原则和应用污染物最大流动距离法划分潮汐河口水库型水源地二级水源保护范围的技术方法。研究利用该方法初步划定了规划中的长江口青草沙水库水源保护区范围，结果表明该方法概念清晰．简单实用．可靠性强。
Reviews on the technical methods for water source protection zoning was made. At present, domestic methods for water source protection zoning have some shortcomings in scientificalness and applicability when used in tidal estuary. According to the characteristics of tidal estuary such as back-and-forth flow and risk of encountering accidental chemicals spillage, a principle of making full use of the self-purification capacity and a means of pollutant maximum travel distance were provided for the water source protection zoning. This method has been used to delineate a water source protection zone for Qingcaosha Reservoir in Yangtze estuary, and was found simple, practical and reliable for use, as well as clear in its conception.
