Abstract: This paper adopted a combination of the PSR model and the RBF model to conduct an early warning analysis of the ecological security system in the Xijiang River basin and the cities along the river from 2013 to 2022.The results showed that although the overall ecological security status of the basin was stable, there was still room for improvement. Nanning City performed well in relevant aspects, while Laibin City still faced significant ecological pressure. Based on the analysis results, relevant suggestions were proposed to further promote the implementation of ecological security and green development strategies in this region.
