文章分析2012年2月至7月对巢湖总有机碳（TOC）的春夏季节变化及空间分布特征，探讨TOC与环境因子（包括水温（WT）、透明度（SD）、溶解氧（DO）、pH值、总氮（TN）、总磷（TP）、叶绿素a（Chl a）等）之间的关系.结果表明：2012年2月～7月间巢湖TOC的浓度呈逐月递增趋势，7月份达到最大值，浓度范围为37.27～60.98 mg/L. Perason相关分析显示（n=59）：巢湖TOC与WT（r=0.617，p<0.01）、pH值（r=0.589，p<0.01）、TP（r=0.653，p<0.01）、Chl a（r=0.659，p<0.01）之间均呈显著的正相关，与SD（r=-0.462，p<0.01）呈显著负相关，与DO和TN没有相关性.

In this paper,seasonal variations and spatial distribution of total organic carbon(TOC)concentra-tions were studied from February to July 2012 in lake Chaohu,and the relationships between TOC and envi-ronmental factors (such as water temperature,transparency,dissolved oxygen,pH,total nitrogen,total phos-phorus,Chl a)were discussed.The results showed that TOC concentrations increased gradually during Febru-ary and July 2012,and ranged between 37.27 mg/L and 60.98 mg/L.The maximum of TOC concentration ap-peared in July.According to perason’s correlation analysis (n=59),positive correlations between TOC and WT(r=0.617,p<0.01),pH(r=0.589,p<0.01),TP(r=0.653,p<0.01),Chl a(r=0.659,p<0.01)were observed, while it had negative correlation with transparency (r=-0.462,p<0.01) and no significant correlation with DO and TN.
