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, the habitats of marine organisms have been affected. This study is based on the Landsat TM remote sensing data and the nearest relative historical survey data (1987, 2005, 2007, 2008, 2009, 2010 and 2011) from the Tianjin of Bohai Bay. We used the multi-resolution segmentation and nearest-neighbor classification methods, and analyzed the relationships between species composition, abundance, biomass and diversity of the macro-benthos, and t water 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 shallow water, coastline increase, polychaete proportions, total macro-benthos abundance and biomass were all positively correlated with each other. It is evident that
