摘　　要：调查了黑龙江省不同地区的水域 ,雌雄异体水螅为广泛分布 ,雌雄同体水螅为稀少分布 .生活于无机离子丰富水域的水螅用原生境池水方能正常生活和生殖 .生活水域 p H 6.3～ 7.6之间 .黑龙江省分布的水螅 ,雌雄异体的强壮水螅和大庆水螅为优势种 .The waters of different regions in Heilongjiang province is investigated. It is found that dioecious Hydra is widely distributed, while hermaphroditic Hydra is rarely. The Hydra that lives in inorganic ion-rich water can normally live and reproduce only in the water of natural habitat. The pH of living water is between 6.3 and 7.6. The dioecious Hydra robusta (Iт 1947) and H. dagingensis (Fan 2000) are dominant species among the entire Hydra, which distribute over Heilongjiang province.
