Changes in the ecosystem service values under the disruption of human activities in national or regional differences and their comparative studies can provide an effective guideline for integrated coastal management and related spatial planning. The data used in this study consist of satellite images Landsat TM/OLI medium-resolution images with GIS analysis tools, we study the spatial and temporal changes of ecosystem service values of the Xiangshangang Bay, Zhejiang of China and Tampa Bay, Florida of USA under the influence of human activities. Results show that: (1) In the past 30 years, the Xiangshangang Bay basin mainly consisted of farmland and forests, while the Tampa Bay basin was dominated by cities and forests. The area of unnatural ecosystems of the two estuaries was larger than that of natural ecosystems, which was the main factor affecting the ecological difference of the study area. (2) As the intensity of human activities was increasing and the scope of development and utilization expanded, in the study period, the amount of ecosystem services in Xiangshangang Bay decreased by 397.64×106 yuan, while that of Tampa Bay decreased by 1186.73×106 yuan. (3) The spatial distribution of ecosystem service values of the two estuarine watersheds is negatively correlated with the level of regional economic development. Traffic distribution, agricultural production and urban development stages have a significant impact on the distribution of ecosystem service values. (4) The management experience of the "Tampa Bay Estuary Conservation Plan" since the 1990s can be used for reference for the development and utilization of the Xiangshangang Bay. Multi-disciplinary planning, to be enlightened at the same level of domestic harbor management, should strengthen cooperation and exchange with neighbouring areas.
