Based on panel data of 30 Provinces in China from 2011 to 2020,this paper used entropy method,coupling coordination degree model and obstacle degree model to explore the coupling coordination relationship between forest resources protection and green development and its obstacle factors.The results showed that the overall coupling coordination level of forest resources protection and green development showed a steady and slow upward trend,and the coupling and coordination level continued to be slightly unbalanced,and the continuous lag of forest resource protection and green development was the key to restrict their further coordinated development.There were obvious differences in the coupling coordination degree among the seven regions,north China,east China and northeast China were nearly disorder,while southwest China,south China,northwest China and central China were mildly disorder.In north China,where the level of forest resources protection and green development had a high level of coupling coordination,there were low levels of regional coupling coordination with both low or unbalanced development levels;The per capita forest stock,the proportion of plantation area in the forest area,and the passenger volume of public transport per 10,000 urban people were the main factors restricting the coordinated development of the two systems.Finally,some suggestions were put forward to promote forest resources protection and green development.
