摘　　要： 采用综合营养状态指数法(TLI))和卡森指数评分法对高州水库2004年到2008年的水质进行了评价,结果显示,近年来高州水库两库区3月份的综合营养状态指数值TLI(∑)近年来呈上升趋势。石骨库区和良德库区2008年3月份的综合营养状态指数值分别达到了40.32和48.07。两库区3月份都呈现出即将突破中营养化状态达到富营养化的趋势。卡森指数评分法得出水库2004-2008年的分值在45.0-68.2之间,自2005年以后,每年3月份的富营养程度要高于9月份,且三月份呈明显的上升趋势。表明了2-3月份是高州水库水华爆发的危险期。在实地调研的基础上,分析了主要的污染原因,并提出了针对高州水库的富营养化控制措施和建议。 After evaluated Gaozhou county reservoir water quality based on comprehensive nutrition state index method and carson index evaluation method during 2004 to 2008, it showed a obviously rising trend of the TLI （ ∑ ） in both two reservoir in march. The TLI （ ∑ ） in ShiGu reservoir and LiangDe reservoir reached 40. 32 and 48.07 respectively. This indicated a break- through from medium nutritional status to eutrophication in both reservoir during March. The results of Carson index evaluation method during 2004 - 2008 was between 45. 0 and 68. 2. The eutrophication level in March, which showed a rising trend, was higher than in September after 2005. Verified that 2 - 3 month is the high - risk period of eutrophication. On the basis of investigation, this research analysed the main pollution causes, and gave the feasible measures and suggestions to control the eutrophication in GaoZhou county reservoir.
