Construction of the ecological security pattern is an effective way to coordinate the relationship between regionally ecological protection and economic development. Due to the differences in the supply and demand of ecosystem services, different levels of administrative districts have the misalignment and disconnection of spatial structures in the construction of ecological security patterns. From an integration perspective, this study attempts to integrate the state and county scales in the Ili Valley region to construct an ecological security pattern for Zhaosu County. Firstly, the ecological source sites were identified based on ecosystem service evaluation, and the integrated resistance surfaces were constructed and ecological corridors were identified using circuit theory model. The results showed that a total of 24 ecological source sites with an area of 2504.47 km2 were identified in Zhaosu County, mainly in the central basin, northern and southern mountainous areas of Zhaosu. The land use types were mainly arable land, grassland and forest land. 50 ecological corridors with a total length of 200.17 km were identified. Compared with the construction of ecological safety pattern at single scale, the integration of different scales can significantly improve the fragmentation of regional habitats and enhance regional landscape connectivity. This study provides a technical framework for integrating ecological safety patterns at different scales, and the results can provide an effective reference for optimizing the spatial pattern of the land in the Ili Valley.
