Abstract: Taking case of Anhui’s 72 counties, the paper is based on PSR model. Forest ecological carrying capacity is evaluated and compared from 2001 to 2016 by entropy weight and expert method and comprehensive index to analyze spatial variability of the the forest ecological carrying capacity, and gravity analysis model is used to explore evolution law of the forest ecological carrying capacity gravity center in Anhui province based on GIS.The results show that government forestry investment intensity, the proportion of natural forest protected area,proportion of converted farmland to forest area and forest structure index weight are bigger.Anhui forest ecological carrying capacity index is better overall, most counties in the province are in the loading grade.however, its distribution is unbalanced in the different counties and the southwest forest ecological carrying capacity is the highest, the north is lowest.The forest ecological carrying capacity gravity center shifted from northwest to southeast from 2001 to 2006, and thereafter moved from the southeast to northeast from 2006 to 2009,at last it migrated to the southeast again until 2016 and the speed of migration was obviously accelerated.
