Abstract Took Chengdu-Chongqing Twin-City Economic Circle (CCTCEC) as the research object, and the ecological source areas were firstly identified based on Land-use datasets and the evaluation of ecosystem importance. The GIS spatial analysis technology, minimum cumulative resistance (MCR) model and night lighting optimization method then were applied to establish the regional ecological resistance surface.Finally, gravity model was used to identify key ecological corridors and ecological nodes to construct the ecological security pattern of the study area. The results showed that the ecological sources of CCTEC cover 24.8% of the total territory and mainly located on the east, south and west areas. 193 ecological corridors with the length of 6441.81km were successfully identified, and the density decreases from the east to the west in space. The key corridors account for 46.56% of the total identified corridors, which mainly distributed in the Northeast of study area including Dazhou, Wushan and Wuxi. Comprehensively, the "dual cores-two axes-half surrounded" spatial pattern had appeared.

Key words： Chengdu-Chongqing Twin-City Economic Circle (CCTCEC) ecological security pattern minimum cumulative resistance model gravity model
