| 摘 要： | 2005年3月至2007年2月对淮北采煤塌陷区两个小型湖泊(南湖和乾隆湖)轮虫的群落结构进行了连续两年的调查.南湖共检测到轮虫9属14种,乾隆湖共计15属27种.乾隆湖轮虫年平均密度为1916 ind./L,约为南湖(198.4 ind./L)的近10倍.乾隆湖和南湖轮虫的最大密度分别为6915和1185 ind./L.在南湖和乾隆湖轮虫的季节动态中,冬、春季以前额犀轮虫为主,夏、秋季以多肢轮虫、异尾轮虫为主.在南湖,长肢多肢轮虫、暗小异尾轮虫和小链巨头轮虫分别占年平均密度的24.4％、24.0％和23.0％.在乾隆湖,暗小异尾轮虫、长肢多肢轮虫和裂痕龟纹轮虫分别占年平均密度的31.5％、27.2％和7.3％.南湖和乾隆湖轮虫的Shannon-Wiener指数范围分别为0～2.06和1.28 ～2.68,平均值分别为0.67和1.99.水温、营养盐和浮游植物生物量对淮北采煤塌陷区小型湖泊轮虫的群落结构具有重要影响.

| Abstract: | The community structures of rotifers and their seasonal variations in small lakes(Lake Nanhu and Lake Qianlong,) in an excavating coal subsidence region in Huaibei city have been investigated from March 2005to February 2007.A total of fourteen species have been recorded,belonging to nine genera in Lake Nanhu,and twenty-seven species belonging to fifteen genera in Lake Qianlong.Average density of rotifers in Lake Qianlong(1916ind./L) is about 10times higher than that in Lake Nanhu(198.4ind./L).Maximum density of rotifers is 6915ind./L in Lake Qianlong and 1185ind./L in Lake Nanhu.Rhinoglena frontalis is dominant species in winter and spring,while Polyarthra spp.and Trichocerca spp.are dominant species in summer and autumn.Among annual average density of rotifers in Lake Nanhu,Polyarthra dolichoptera,Trichocerca pusilla and Cephalodella catellina are 24.4%,24.0% and 23.0%,respectively.Among annual average density of rotifers in Lake Qianlong,Trichocerca pusilla,Polyarthra dolichoptera and Anuraeopsis fissa are 31.5%,27.2% and 7.3%,respectively.The ranges of Shannon-Wiener indices in Lake Nanhu and Lake Qianlong are 0-2.06and 1.28-2.68,with average values of 0.67and 1.99,respectively.The community structures of rotifers in the small lakes of an excavating coal subsidence region in Huaibei city are influenced by water temperature,nutrients and phytoplankton biomass. |
