Abstract: In order to construct the system of nature reserves with Chinese characteristics, it is necessary to strengthen the basic research on the spatiotemporal evolution patterns of ecological functional nature reserves. Given the unique natural geological environment of Sichuan Province, we made an analysis of the spatial distribution characteristics and evolution process of ecological functional nature reserves from 1965 to 2015. The results showed that: 1) ecological functional nature reserves in Sichuan Province were mainly in clusters in terms of spatial distribution; 2) the spatial distribution of ecological functional nature reserves in Sichuan Province was imbalanced with a big gap between 21 prefecture-level regions through 50 years’ development, but is developing towards a balanced distribution; 3) the spatial distribution has evolved into a pattern dominated by high-density multi-core areas and high-density scattered zones and belts around Sichuan Basin, with high-density scattered zones and belts in western and southwestern Sichuan; 4) the center of nature reserves in Sichuan Province has transferred from northeast to southwest, getting closer to the center of Sichuan Province.
