摘　　要：2015年3月对洪湖、梁子湖进行了水质监测。依据实测数据,结合洪湖湿地自然保护区和梁子湖林业局监测数据和文献数据,采用综合营养状态指数法对洪湖、梁子湖的富营养化状态进行评价;并根据各因子在综合营养状态指数中所占比重和地表水水质标准,对各因子做了比较。结果表明:洪湖、梁子湖综合营养状态指数分别为57.2、42.5。即洪湖为轻度富营养、梁子湖为中营养;各因子对洪湖、梁子湖富营养化的贡献大致相同,即Chla为首,TP、COD_(Mn)和SD次之、TN最后。In March 2015, water quality of Hong Lake and Liangzi Lake was monitored. On the basis of the monitored data as well as the monitored and document data collected by Honghu wetland nature reserve and Liangzi lake forestry bureau, the eutrophication status of Hong Lake and Liangzi Lake was evaluated by use of TLI. According to the analysis of the proportion of each factor in method TLI and the Environmental Quality Standard for Surface Water, all the factors were compared. The results showed that the status of Honghu Lake and Liangzi Lake was light eutrophic（TLI 57.2） and mesotrophic（TLI 42.5） respectively. Contributions of each factor to the eutrophication of Honghu Lake and Liangzi Lake were roughly the same in method TLI, namely, Chla was dominated, followed by TP, COD_（Mn）, SD and TN in a descending order.
