Abstract:: In order to explore the regional differences and convergence of ecological security in Anhui section of Huaihe Eco-economic Belt，and realize high-quality coordinated development of each region，by constructing the evaluation index system of ecological security，entropy method was used to measure the level of ecological security in Anhui section from 2010 to 2018，and Dagum Gini coefficient decomposition method was used to analyze the contribution and source of regional differences. The convergence of regional differences in ecological security was tested by coefficient of variation method. The results show that:(1)from 2010 to 2018，the level of ecological security in Anhui section of Huaihe Eco-economic Belt kept increase year by year，and the average annual composite indices were 0.259，0.265，0.299，0.447，0.345，0.323，0.432，0.478;(2)the spatial difference of ecological security level development in Anhui section was obvious; the average contribution rate of regional difference and regional difference to the overall difference was 48.7% and 46.1%，respectively;(3)both north of Huaihe River and south of Huaihe River had σ convergence characteristics. In summary，the level of ecological security in Anhui section of Huaihe Eco-economic Belt is not optimistic，and there are obvious differences between and within regions. Therefore，the main development direction is to improve the level of ecological security，to take measures according to local conditions，and to reduce the regional differences of ecological security.
