【摘要】 <正> 浙江省境内地势西南高,东北低,呈阶梯形倾斜。西南为山地,中部是丘陵和盆地,东北则为平原。全省从北至南分布有苕溪、钱塘江、曹娥江、甬江、灵江、瓯江、飞云江和鳌江等八大水系,具有众多的溪沟汇流入江;滨海地区又泛串杭嘉湖、宁绍、温瑞三大平原;外荡、水库遍及各地。淡水鱼类种类繁多,资源丰富。关于浙江省淡水鱼类区系成分及其区划地位的研究工作,以前做得不多。仅对瓯江、灵江的鱼类区系分别进行过初浅的论述。李思忠(1981)曾对浙江省区划有过大致的划分。此外,对甬江的鱼类区系、舟山群岛的淡水鱼类分布区划等作过探讨。浙江省淡水水产研更多还原

【Abstract】 On the basis of specimens collected from Zhejiang Province during 1982-1987, the authors make a preliminary survey of the fauna and geographical distribution of fresh-water fishes in Zhejiang Province. The main results are summarized as follows: Using Nikolsky’s unit of analysis in zoogeographical studies-the faunacomplex-the authors made an analysis of 147 specimens of 20 families of native fresh-water fishes in Zhejiang Province and came to the conclusion that these fishes comprise five different fauna-complexes:(1) Fauna-complex of China plain:87 species (59.2%); (2) Fauna-complex of India plain:54 species (36.7%);(3) Fauna-complex of China-India mountain:4 species(2.7%); (4) Fauna-complex of Northern plain:l species (0.7%); (5) Fauna-complex of Northern mountain:1 species(0.7%).更多还原
