西昌市邛海湖鹅掌河入湖口枯水期水质调查研究

研究以西昌邛海湖南侧入口支流——鹅掌河2005～2008年枯水期入湖水质为研究对象，以国标法为检测标准，通过对流域枯水期入湖水的pH、化学需氧量（COD）、悬浮物（SS）、总氮（TN）、总磷（TP）的实验检测与肯达尔检验科学核算，得出这一流域近几年枯水期入湖水质状况除TP外，其他指标均为地表水Ⅰ类～Ⅱ类，TP略超地表水Ⅱ类标准，但总体较好。以鹅掌河流域内社会经济发展状况以及自然环境变化等因素为依据，分析了对鹅掌河流域水质产生较大影响的污染源，希望为鹅掌河流域污染控制和水环境保护提供一定的科学依据。

Water Quality Research in Dry Season of Xichang Qionghai Lake Ezhang River Estuary

With southern entrance of Xichang Qionghai Lake—Ezhang River water quality in dry season during 2005-2008 as study object,and national standard method as detection criteria,through experimental test and Kendall Test scientific account about pH,chemical oxygen demand (COD),suspended solids (SS),total nitrogen (TN),total phosphorus (TP),it was showed that except for TP,other indicators are between I-II type,TP slightly exceed II standard,but the general situation of water quality is good. According to factors of social and economic development and nature environment variation,the main influencing pollution sources for water quality of Ezhang River basin were analyzed,so as to provide scientific basis for pollution control and water environment protection.
