Abstract：Construction of resource and environment carrying capacity monitoring and prediction mechanism has been listed as one of the major tasks of the comprehensively reform guided by the government.The tidal flat resource is a superior resource in the adjacent sea area along the Yangtze River Economic Belt.Evaluation of its ecological carrying capacity will be an important part of assessment of the overall marine ecological carrying capacity.Based on multi-source and multi-temporal data,a remote sensing-based tidal flat ecological carrying capacity evaluating index system is built.Which reflects the change of tidal flat ecosystems by the preserving rate of tidal flat area and the rate of change of vegetation coverage in typical habitats,and then comprehensively analyzes the tidal flat ecological carrying capacity.The result shows that the ecological carrying capacity of the tidal flats in the adjacent sea area along the Yangtze River Economic Belt can be divided into three types:overloaded,critical overloaded and loadable,accounting for 44%,28% and 28% respectively.Human activity is the main reason for overload.This paper reveals the current status of ecological carrying capacity evaluation in the Yangtze River Economic Belt and provides advanced technical means and scientific data for further research.
