Ecological quality status of Liaodong Bay using benthic indices
摘要
Abstract
On the basis of the analysis of macrozoobenthos samples and environmental materials collected from Liaodong Bay in July 2007,W-statistic was used for the first time to assess the ecological quality status of the study area. In addition, Shannon-Wiener biodiversity index and Benthic Index of Biotic Integrity were employed to comprehensively analyze the ecological quality status of the area. The results of the analysis indicated that majority of the sampling sites in the offshore area were slightly disturbed; however, the areas located in the coastal areas, especially those in the Daliao River and Shuangtaizi River estuaries, were significantly disturbed and a spatial gradient was observed from the estuaries to the offshore area. This spatial pattern may have occurred because of the large amount of industrial and municipal wastewater being discharged every year from Liaoning Province into the Liaodong Bay through land streams, causing severe eutrophication in the northern coastal areas especially near the estuaries. Furthermore, all the indices exhibited sensitivity toward the spatial gradient of the Eutrophication Index (EI) and showed significant relations with EI. These relations were also observed among all the biotic indices that could identify the differences between the macrozoobenthos communities in the north estuaries group and those in the coastal areas group. It was concluded that all indices used in the study were suitable for assessing the ecological quality status in the Liaodong Bay.关键词
