中文摘要：

2007年1-12月对中国科学院太湖湖泊生态系统站栈桥附近进行了每月1次以及太湖4个典型湖区每季度1次的有机碳生产实验，分析了太湖浮游植物群落的有机碳生产情况及其影响因子．结果表明，浮游植物有机碳生产与光照、温度以及浮游植物的群落组成有着密切的关系．春、夏季浮游植物光合效率比秋、冬季高，空间上蓝藻占优势的湖区较高，水草区较低．

英文摘要：

The organic carbon production of phytoplankton near the Trestle monthly and at four stations quarterly in Lake Taihu from January 2007 to December 2007 was investigated, and its influence factors were analyzed. The results showed that there were obvious temporal and spatial differences in the production of organic carbon in Lake Taihu. The high values of organic carbon production were recorded in spring and summer. The production of organic carbon was higher in the area where the phytoplankton was dominated by Cyanophyta and lower in the aquatic areas.
