Abstract: Resource development and utilization are followed by landscape changes and lower ecosystem stability in the compound mineurban area. Assessment of landscape ecological risk is becoming a hot topic. We assessed the landscape ecological risk of the northern coal mining area of Peixian County in Xuzhou City. The ecosystem services were used to reveal the shifts of landscape vulnerability. The unbalance index and inconsistent index were introduced to represent the distribution of landscape ecological risk. Further, the drivers of ecological risk dynamics during 2000 to 2019 were analyzed. Results showed that: (1) the areas with high landscape disturbance degree were mainly distributed in the adjacent areas of Weishan and Zhaoyang lakes and construction land; the vulnerability of the whole landscape decreased first and then increased; (2) the landscape ecological risk increased as a whole, while the middle and high-risk areas had transferred from coal mining areas to towns; (3) the spatial variation of ecological quality and human population in different towns tended to be similar; (4) With a 1% increases of urbanization rate and raw coal output, the ecological risk value would increase by 1.081% and 0.091%, respectively. Our results can provide reference for the ecological protection and rational development in the mining area of eastern plain with high groundwater level.

Key words: landscape ecological risk assessment, mine-urban compound area, ecosystem services value, landscape pattern index.
