Abstract: This article studied the community composition and biodiversity characteristics of macrobenthos under the intense environmental disturbances and analyzed the pollution status of sampling stations in three areas of Alkaline Factory, Port region and Nuclear Power Station off the coast of Lianyungang. The result shows that polychaete and mollusk are the dominant species which are 42.703%, 51.352%,56.03% and 46.085%,38.145%,32.034% of the total individual numbers, respectively in the three areas. The average value of Shannon-Wiener and evenness index in the region of Nuclear Power Station are the biggest which are 3.184 and 0.868, respectively, and the values in the Alkaline Factory are the smallest. The biggest average value of richness index is in the Port region which is 1.416, and the smallest value is in the Alkaline Factory. There is a approximate inverse relation between macrobenthos richness index and median grain siz

Key words: species biodiversity, coastal area of Lianyungang, benthos community structure, species biodiversity, coastal area of Lianyungang
