【摘要】 当前我国饮用水水源受到较严重的污染,饮用水水源保护形势严峻。因此,建立水源保护区来保护供水源水质,已经刻不容缓。建立饮用水源保护区是保护饮用水水源的关键措施,也是保护水源地的最强手段。对于水源保护区划分方法以及划分范围的确定,《饮用水源保护区划分技术规范》也定性、定量地提出了一些划分方法,并对保护区的划分范围做了一些规定。然而,要让水源水质真正得到合理的保护,应该将此规范中规定的基本模型根据河流类型进行细分,并选择适合所研究河流类型的划分方法进行计算。本研究通过对国内外相关著作、论文的阅读,利用水环境动力学理论,结合岷江航电库区犍为段水质水文状况分析岷江航电库区污染物迁移过程,建立二维水质模型对一级保护区、二级保护区以及准保护区的污染物浓度扩散边界条件进行模拟分析计算,得到保护区内各污染源对库区的水质以及下游取水点的影响情况,并对保护区的划分尤其是准保护区提供有利的数据支持,随后提出水源地保护区技术管理措施。本文主要围绕研究区水文地质条件分析与水源地保护区的研究两方面展开,研究成果主要有:1、岷江水体水质状态稳定,犍为航电枢纽库区蓄水后,库内水体水质将保持良好,在水源一级保护去区能达到Ⅱ类水体质量标准。可作为犍为县城镇生活饮用水水源。2、按照规范划定的水源地一级保护区、二级保护区以及准保护区能有效保护水源水质,在保护区各级边界能达到要求的水质标准。3、通过对岷江航电库区污染源的数值模拟分析,确立了各级水源保护区的水质控制目标并因此提出了技术管理措施。

【Abstract】 At the moment, the drinking water source that is in the grim situation suffers severe pollution in china. Therefore, establishing water reserves to protect water quality of the source is urgent. Establish drinking water reserves is not only the key measures to protect drinking water sources, but also the strongest means water to protect the source. The drinking water reserves division technical specifications has both qualitative and quantitative put forward some partition methods for determining the dividing method and scope of the water reserves, and it also made some provisions differentiate limits for the reserve. However, if we want quality of the water resource really get reasonable protective, we should according to the river pattern to classified basic model provisions of the standard stipulation carefully, and we should also choose the suitable dividing method of the studied river to calculate.By researching the domestic and foreign relevant books, papers, using water environmental dynamics theory, and combining with the water quality and hydrology condition of QianWei in Minjiang River Avionics, We have analyzed the pollutant migration process of Minjiang River Avionics and have established pollutant concentration diffusion boundary conditions of Water quality model of two-dimensional in primary reserves, secondary reserve and prospective reserves and simulation calculation. We have got the influence condition of pollution resource which has influenced the water quality of reservoir area and the downstream water point in various sources protection zones. We have provided favorable data support for reserve division, especially must reserve, then we have proposed water reserve technical management measures in water reserves areaThis article is focusing on two aspects, one is analyzing water quality and hydrology in study area, the other is researching the water reserves. We have got several research achievements. First, Minjiang River water is in a stable status, and after QianWei reservoir for navigation-power junction has impounded, the chambers water which can achieve II class water quality standards the first-grade protection zones of the water resource is keeping so good that can be used as drinking water in JianWei. Secondly, according to the regulation, the first-grade protection zones of the delimited water and Secondary reserve source and prospective reserve can effectively protect the water quality, and it also can meet the requirements of the water quality standards at various levels in reserve border. Thirdly, through numerical simulation analysis for the pollution resource in Minjiang River Avionics, we have established the quality control goals of water resource at all levels, and thus we have put forward some technical management measures.
