摘　　要：为了解会仙湿地水质现状,本文检测会仙湿地毛家村段分毛家村渡口、小水潭入水口、水泥桥下、鱼和水草较多处、大水潭、农田旁、水域较宽广处7个采样点的细菌菌落总数、大肠菌群数和粪大肠菌群数的季节变化动态。结果表明,会仙湿地水质的细菌总数在一年四个季度的平均值分别为:2 314、27 000、1 500、3 414cfu·mL-1,表现出夏季较其他三季细菌菌落总数明显增长趋势;采样多管发酵法测得四季大肠菌群数为:8 971、1 901、3 823、512MPN·L-1,粪大肠菌群数为:4 385、432、<20、85MPN·L-1,表现出春季较其他三季大肠菌群数、粪大肠菌群数明显增长趋势。Investigation has been done into Huixian Wetland in which track tests were carried on for one year in terms of Total Bacterial Count, Total Coliform; Fecal Coliforms and 7 samples were taken from different places of Huixian. The total bacteria （mL^-1）, Coliforms （mL^-1） and Fecal coliform were analyzed by microbiological methods. The results indicate that the number of Coliform（mL^-1 ） is 8 971, 1 901,3 823,512, Fecalcoliforms（mL 1） 4 385 , 432 , 〈20 , 85 and total bacterial 2 314,27 000, 1 500, 3 414, which shows clearly that the total bacteria rise evidently in summer. By multi-tube fermentation method, the number of Total Coliforms is 8 971, 1 901,3 823,512 MPN·L^-1 and Fecal Coliforms is 4 385,432, 〈20, 85 MPN · L^-11. The results indicate that Total Coliforms and Fecal Coliforms rise evidently in spring.
