摘    要:通过对神女溪大规模水华进行现场监测和调查,结合当地水文、气象、污染源调查资料,并运用对比、相关分析等方法对神女溪水华原因进行了综合分析,认为叶绿素a与溶解氧、氧化还原电位、总氮、总磷、高锰酸钾指数均存在正相关关系,与pH和电导率呈负相关关系,总磷是此次水华的限制因子.

The Study of the Waterbloom Occurring in Shenv Brook
WANG Min. The Study of the Waterbloom Occurring in Shenv Brook[J]. Environmental Monitoring in China, 2008, 24(1): 60-63
Authors:WANG Min
Abstract:By the investigation more large-scale waterbloom condition in Shennv Brook's monitors,hydrology meteorological data during that period when waterbloom happens,upper reaches contaminates the source investigation,union contrast the Yangtse River and the Baolong river's nutrition situation,reaches the Shennv Brook waterbloom's happen being that condition such as hydrology and meteorological phenomena leads to synthetically.And apply relevance analysis method to have carried out analysis on many Shennv brook's waterbloom emergence period factors.The correlativity between chlorophyll-a and the parameters of dissolved oxygen,oxidation-reduction potential,total nitrogen,total phosphorus,potassium permanganate is positive.The correlativity between pH and Electrical conductivity is negative,analysing such that the phosphorus is the waterbloom happens to restrict.
Keywords:Shennv Brook  Waterbloom  Backwater area  Eutrophication
