| 中文摘要: |
| 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型冷水型鱼类为主，且种类较少，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物种组成和质量密度有显著差异。总之，与相邻山区的河流相比，湑水河鱼类资源较为丰富，但目前人为因素已经开始影响鱼类的正常生存，应当加以重视。 |

| In this work we conducted surveys on the fish resources in Xushui River in September 2009 and May 2010. A totally of 29 fish species were found in the river basin，which belonged to 4 orders and 10 families. There were mainly the mountain，streams and cold water fish type at Taibai section in the river upstream , and the fish species were relatively fewer. At Chenggu section in the in the river downstream , where the elevation was low , the fish species were abundant . The two river sections showed significant differences in composition and mass density of fish species in different seasons. In compared with the adjacent mountain rivers , the fish resources in Xushui River were relatively abundant . However , external factors have begun to affect the survival and reproduction of the fish species. River pollution and other anthropogenic interference may cause irreversible ecological impact on the fish resources in Xushui River |
