Abstract:By investigating the zoobenthos in the Jiangsu section of the Yangtze River in September 2004, December 2004 and March 2005, 58 species of zoobenthos were found out in the Jiangsu section of the Yangtze River, including 12 species of Annelida, 16 species of Mollusca and 30 species of Arthropoda. The average density of the zoobenthos in the Jiangsu section of the Yangtze River was 95.03 ind/m^2. The density was 115.74 ind/m^2 in flood period, 127.07 ind/m^2 in usual dischange period, and 42.27 ind/m^2 in drought period, respectively. The dominant species were Tubifex sincus, Oncomelania sp. , Nereis japonica, Corbicula fluminea and Branchiura sowerbyi. The Shannon-Wiener species diversity index of the Jiangsu section was 3. 281. It could be overall evaluated that the average water quality in the Jiangsu section was slightly polluted.
Keywords:The Yangtze River  Jiangsu  zoobenthos  environment  species diversity  resource
