摘要 矿城复合区在资源开发利用过程中普遍存在景观格局剧烈变化、生态系统不稳定等特征,开展景观生态风险评价也成为多学科关注的热点。本研究以江苏省徐州市沛北煤矿区为案例,采用生态系统服务价值表征景观脆弱度,引入不均衡指数和不一致指数反映景观生态风险分布特征,开展2000—2019年景观生态风险驱动力分析。结果表明:(1)景观干扰度较高的区域主要集中在紧邻微山和昭阳两湖区、建设用地及其四周,景观脆弱度整体先减小后增大;(2)景观生态风险整体上有所增强,中高风险区域由煤矿区向各镇区转移;(3)各镇区生态和人口的空间演变大多趋于一致;(4)城镇化率、原煤产量每增加1%,生态风险值将增加1.081%、0.091%。研究结果可为东部平原高潜水位煤矿区生态保护与管理、区域合理有序发展提供参考依据。 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.
