摘要
采用2009—2015年湖泊监测资料,运用数据回归统计方法,研究云南省九大高原湖泊水体叶绿素a与水温、p H、DO、COD_(Mn)、SD、NH_3-N、NO_2-N、NO_3-N、TN、TP等环境因子的相关性,建立相应的回归方程。结果表明,叶绿素a含量与水温、p H、COD_(Mn)、DO、NH_3-N、NO_2-N和NO_3-N呈正相关,与TN、TP呈显著正相关,与SD呈显著负相关;且叶绿素a的对数与TN、TP的对数呈显著正相关,与TN/TP的对数呈一定的负相关。湖泊可能是磷为藻类生长限制因子的湖泊。削减TN、TP和NH_3-N含量在控制叶绿素a方面具有现实意义。
Based on 2009—2015 year monitoring data of lakes,and applying data regression statistics method,the correlation between chlorophyll a and water temperature,p H,DO,COD（Mn）,SD,NH3-N,NO2-N,NO3-N,TN,TP and other environmental factors in the lakes of nine high altitude lakes in Yunnan Province are studied,and the corresponding regression equation is set up.The results show that chlorophyll a is positively correlated with water temperature,p H,COD（Mn）,DO,NH3-N,NO2-N and NO3-N,prominent positive correlation with TN and TP.There is a significantly negative correlation with SD.The logarithm of chlorophyll a was positively correlated with that of TN and TP,and negative correlation with the logarithm of TN/TP.Lakes may be lakes where phosphorus is a limiting factor for algae growth.It is of practical significance to reduce the content of TN,TP and NH3-N in the control of chlorophyll a.
