渤海湾近海栖息地变化对大型底栖动物群落结构的影响
Impact of marine habitat changes on macro-benthos communities in Bohai Bay
摘要
Abstract
Since the start of the 21st century, rapid economic coastal development and active coastal engineering have occurred in China, causing most of the coastline to contract. Large expanses of coastline, mudflats, and near-shore shallow water have been occupied, and the habitats of marine organisms have been affected. Hence, the macro-benthos is now under unprecedented pressure. This study is based on the Landsat TM remote sensing data and the nearest rela-tive historical survey data (1987, 2005, 2007, 2008, 2009, 2010 and 2011) from the Tianjin near-shore region of Bohai Bay. We used the multi-resolution segmentation and nearest-neighbor classification methods, and analyzed the rela-tionships between species composition, abundance, biomass and diversity of the macro-benthos, and the evolution of the coastline, mudflats, and near-shore shallow water in the Tianjin near-shore region of Bohai Bay using eCognition, ENVI and ArcGIS software. The results show that mudflat, near-shore occupied shallow waters, coastline increase, proportion of mollusks and crustaceans, total species numbers in the macro-benthos, Shannon-wiener index, abundance index, and evenness index are all negatively correlated with each other. In contrast, mudflat, near-shore occupied shal-low water, coastline increase, polychaete proportions, total macro-benthos abundance and biomass were all positively correlated with each other. It is evident that changes in the marine habitat have had a significant impact on macro-benthos communities in Bohai Bay.关键词
