江西齐云山自然保护区鱼类资源

FISH RESOURCES OF QIYUNSHAN NATURE RESERVE,JIANGXI,CHINA

江西齐云山自然保护区是省级自然保护区,区内河流全部汇入赣江上游章江源头之一的上犹江。2006年12月和2007年5月,作者对该保护区内野生鱼类资源进行了本底调查。调查发现区内野生淡水鱼类共计20种,隶属于4目9科19属,多为山区溪流小型鱼类,区系组成以鲤科鱼类为主。鱼类物种多样性在空间分布上有所不同,桶江河下游多样性水平最高,可能与这一河段没有受到水坝分隔的影响,自然环境相对原始,较少人为干扰等有关。

Qiyunshan Nature Reserve of Jiangxi, China is one of the provincial protected areas. Most rivers in the reserve flow into Shangyoujiang which is one of the source of the Ganjiang, a tributary of middle Yangtze River basin. Authors made a research on the wild fish resources of the reserve in Dec. 2006 and May 2007, respectively. A total of 20 species, belonging to 19 genera, 9 families and 4 orders, were collected. The fishes of Cyprinidae are the main component on the fish fauna of the reserve. The lower stream of the Tongjiang had richer species diversity, due to relatively stable environment with less influences from dams and local people. We suggested in the research that enhancing the protect level on the core zone of the reserve and removing abandoned dams and ditches built should be necessary so as to recover the position of the reserve.
