| 摘 要： | 2009年9月和2010年5月在湑水河流域对鱼类资源进行了调查,共捕获鱼类4目、10科、29种；湑水河上游太白段以山区溪流冷水型鱼类为主,种类较少；下游城固段海拔低,鱼类种类相对上游河段丰富.不同河段在不同季节的鱼类组成和质量密度有显著差异.与相邻山区的河流相比,湑水河鱼类资源较为丰富,但目前外部因素已经开始影响鱼类的生存与繁衍,河流污染和其他人为干扰可能对该流域鱼类造成不可逆转的生态影响. |

| Abstract: | In this work, the survey about fish resources was carried out in the Xushui River in September 2009 and May 2010. Totally 4orders, 10 families, 29 species fish were found in the river basin. There were mainly the mountain, streams and cold water fish at Taibai county in the upstream of the Xushui River, and fish species were fewer; elevation was low, fish species were abundant at Chenggu county in the downstream. Even for the same species, the density is also significantly different in various part and seasons. Our results indicated that fish resources are more abundant in the Xushui River. At present , human disturbance have staered to influence the fish,living , we should take seriously about them. |
