| 摘 要： | 2001年7月至2003年1月对长江下游的太湖、巢湖和龙感湖水体中可溶性有机碳(DOC)的时空分布进行了研究。结果显示．太湖水体中DOC的平均浓度最高．巢湖次之，龙感湖最低；秋季水体中的DOC浓度较冬季高；藻型湖泊水体中DOC浓度较草型湖泊高；下午水体中DOC的浓度较上午高。水体中DOC浓度的垂直分布无明显的规律性。从周年来看．DOC的浓度随温度的升高而升高。

| Abstract: | On the basis of studies on the DOC temporal and spatial distribution between July 2001 to January 2003 in Tai Lake, Chao Lake and Longgan Lake at the lower reach of Changjiang River : DOC concentration was the highest in Tai Lake, relatively higher in Chao Lake and lowest in Longgan Lake; its concentration in autumn was greater than that in winter, in lake dominated by algae was greater than that in lake dominated by macrophyte, it was greater in the afternoon than that in the morning. There was no apparent law about the vertical distribution of DOC. And its concentration increased with the increasing temperature. |
