摘　　要：利用2008年8月至2009年1月对红枫湖水库叶绿素a及其理化因子的监测资料，分析了红枫湖水库叶绿素a的分布特征及其影响因子，并应用修正的卡尔森营养状态指数（TSI）对各监测点的营养状态进行了排序：结果表明，各监测点叶绿素a含量时空差异较大．浓度在4．52-103．66mg/m^3。叶绿素a与环境因子关系比较复杂，在不同的监测点，对叶绿素a有显著影响的环境因子各有不同，但与水温、pH值表现为显著正相关，与透明度则表现为显著负相关。库区各监测点TSI均大于54，呈富营养化。Based on the monitoring data of ehlorophyll-a and the physiochemical factors in Hongfeng Lake Reservoir from August of 2008 to January of 2009, the distribution characteristics of chlorophyll-a and the influencing factors in Hongfeng Lake Reservoir were analyzed. Using the modified Carlson trophic state index, the trophie states in different sampling sites were ranked. The results showed that the spatial and temporal distribution of chlorophyll-a in the sampling sites were varied strongly, the concentration of chlorophyll a changed from 4.52 mg/m3 to 103.66 mg/m3. The correlation between chlorophyll-a and other environmental factors was more complicated. In different sampling sites, the significant environmental influencing factors for chlorophyll a were different. However, the relationships between chlorophyll-a and WT and pH were positive, and that between chlorophyll-a and SD was negative. TSI in each monitoring site in the reservoir was over 54,being eutrophic.
