| 摘要: |
| 在淮南潘谢矿区内设置3个水文生态环境条件差异较大的小型煤矿塌陷湖泊研究站点,分别为潘谢潘集站(PXPJ)、潘谢顾桥站(PXGQ)和潘谢谢桥站(PXXQ),于20132014年4个季度分别对这3个湖泊的轮虫群落结构组成特征及水生态环境因子影响因素进行分析.共观察到轮虫15属32种,其中PXPJ站点13属25种,PXGQ站点13属24种,PXXQ站点11属20种.3个塌陷湖泊轮虫群落结构具有较大的时空分布差异,主要优势种为曲腿龟甲轮虫、罗氏异尾轮虫、前节晶囊轮虫、卜氏晶囊轮虫和针簇多肢轮虫.PXPJ、PXGQ、PXXQ站点轮虫丰度范围分别为500~2800、950~3350、400~3900ind./L,3个站点Shannon-Wiener多样性性指数的平均值分别为2.71、2.68和2.54,体现了塌陷湖泊β中污染型水质环境的特点.轮虫群落结构与环境因子的冗余分析结果表明:水温、电导率和营养盐等环境因子对淮南采煤塌陷湖泊的轮虫群落结构影响较大. |

| Abstract: |
| Three small lakes at PXPJ site, PXGQ site and PXXQ site in the Huainan Panxie coal mine subsidence areas were chosen as research sites, which were characterized by different conditions in hydrology, ecological and environmental factors. The investigation of rotifer communities and aquatic environmental factors were conducted in the four seasons of 20132014 to address their relationship. A total of 32 species have been recorded, which belong to 15 genera. 25 species of the 13 genera at PXPJ site, 24 species of the 13 genera at PXGQ site, and 20 species of the 11genera at PXXQ site have been indentified. Keratella valga, Trichocerca rousseleti, Asplanchna priodonta, Asplanchna brightwelli, Polyarthra trigla Ehrenberg, Gosse were the dominate species in the lakes. Rotifer abundance were 500-2800ind./L at PXPJ site, 950-3350ind./L at PXGQ site, and 400-3900ind./L at PXXQ site. The average Shannon-Wiener diversity indexes for rotifer communities within the three studied sites were 2.71, 2.68 and 2.54 respectively, indicating β-type of medium pollution water quality in the aquatic zones.Redundancy analysis based on rotifer community and aquatic environmental factors showed that water temperature, conductivity and nutrient in the lakes are the main factors affecting the rotifer communities in those lakes. |
