摘要：[目的]利用蜻蜓目昆虫群落结构,来指示滇池入湖口生态湿地的水质情况。[方法]选取滇池东北岸入湖口湿地—海东湾湖内湿地12个样点,调查了水体理化属性和蜻蜓目昆虫群落结构,划分了水质级别,并计算和比较了不同水质级别下蜻蜓目水生昆虫的指示值和群落特征指数,通过皮尔逊相关分析分析了水生昆虫群落结构、水体理化因子与水质级别以及水生昆虫群落结构与水体理化因子的相关性。[结果]不同水质级别下的水生昆虫物种组成不同,Ⅱ类水质水体中的指示种类为硕综蟌属;Ⅲ类为狭扇蟌属和异痣蟌属,Ⅳ类和Ⅴ类水质水体中未发现指示种类。对于群落特征指数来说,Simpson优势度指数和Shannon-Wiener多样性指数随着水质级别的降低而减小。水质级别与总磷和化学需氧量呈显著正相关,与溶解氧呈显著负相关;蜻蜓目水生昆虫的Simpson优势度指数、Shannon-Wiener多样性指数与溶解氧呈显著正相关,而与总磷呈显著负相关。[结论]本研究认为,可以利用蜻蜓目水生昆虫种类和群落结构特征来指示海东湾湖内湿地水质,从而能间接反应滇池水质情况。
[Objective]To find out the indication roles of Odonata aquatic insects in Dianchi Lake riparian wetland water quality evaluation. [Method]The physicochemical variables were measured and Odonata aquatic insect community structure was surveyed at 12 sites in Haidongwan riparian wetland,the entrance of Dianchi Lake. The water quality levels were classified; The IndVals and community feature indices were calculated and compared. The correlation between the aquatic insect community structure,the physicochemical variables and water quality levels; the aquatic insect community structure and the physicochemical variables were analyzed by Pearson correlation analysis.[Result]The species composition of aquatic insects at different water quality levels was different. Megalestes was the indicator of level Ⅱ. Copera and Ischnura were the indicators of level Ⅲ. There are no indicators of level Ⅳand Ⅴ. For the community feature indices,Simpson dominance index and Shannon-Wiener diversity index decreased with the decrease of water quality levels. The water quality levels were positively correlated with total phosphorus and chemical oxygen demand,and negatively correlated with dissolved oxygen. Moreover,the Simpson dominance index,Shannon-Wiener diversity index of Odonata aquatic insects showed significant positive correlation withdissolved oxygen,and significant negative correlation with the total phosphorus. [Conclusion]Odonata aquatic insect species and community structure characteristics can be used to indicate the water quality of Haidongwan wetland water quality so as to indirectly reflect the water quality of Dianchi Lake.
