Abstract: The paper focused on the evalution of county forest ecological carrying capacity of Zhejiang province that based on Pressure-State-Response(PSR) model with entropy weight and expert method to calculate the weight and combined the state-space techniques and vector mode with GIS to analyze the space-time distribution patterns and its spatial correlation of 71 counties from years of 2001 to 2016. As a result, firstly, Zhejiang province’s forest ecological carrying capacity (ZFEC) is in a moderate loading area with continuously improvement in the whole, and the indexes of the tree cutting intensity, forest fire disaster rate, unit area GDP, unit area industrial output value expressed maximum weight. Secondly, the distribution of ZFEC is exceptionally unevenly distributed, with the highest level of carrying capacity in the southwestern part ,followed by the middle part and the lowest in the northen part. Finally, the ZFEC shows significant spatial auto correlation and spatial aggregation with the most significant high-high clustering and mainly concentrates in the southwest districts of Zhejiang province.
