摘要

本文依据尼尔基水库2011—2015年水质监测数据,分析了尼尔基水库叶绿素a含量的时间、空间变化特征,选取应用综合营养状态指数法对尼尔基水库的富营养化程度分区域进行评价:利用SPSS软件中的逐步回归方法,探讨叶绿素a与水环境因子的关系,在此基础上建立了叶绿素a的预测模型,对叶绿素a的预测值与实测值进行了拟合对比分析,并结合尼尔基水库的现有问题,给出了水体富营养化的防治措施。结果表明:尼尔基水库营养化等级总体上来看处于中营养和轻度富营养化状态;与叶绿素a的浓度呈现显著相关的因子有总氮、总磷、硝酸盐氮、氨氮、透明度、化学需氧量。
Based on 2011-2015 Nierji reservoir water quality monitoring data,analysis Nierji reservoir variation characteristics of time,space,content of chlorophyll a,selection of Nierji reservoir using comprehensive nutrition state index method to evaluate the eutrophication degree of points area;The stepwise regression methods of SPSS software,this paper discusses the chlorophyll a and water,the relationship between'environmental factors and to establish the forecast model of chlorophyll a,the fitting for predicted values and the chlorophyll a comparative analysis of existing problems on the basis of combining Nierji reservoir,the eutrophication control measures are given.The results show that the three Nierji reservoir monitoring points of the chlorophyll a concentration remained the same change trend.Nierji reservoir eutrophication level overall in nutrition and mild in eutrophication condition.Nierji chlorophyll a reservoir prediction model is meaningful to have four,we can find that related to the concentration of chlorophyll a show significant factors of total nitrogen,total phosphorus,nitrate nitrogen,ammonia nitrogen,transparency,chemical oxygen demand,with the total nitrogen,total phosphorus,nitrate nitrogen,ammonia nitrogen concentration is significantly positive correlation,that is to say,when the concentration of them is larger,the greater the concentration of chlorophyll a,is negatively related to the transparency and chemical oxygen demand,and correlation of pH,potassium permanganate index and chemical requirements not reflected in the model.
