| 摘 要： | 喀斯特岩溶区是地球上最脆弱的自然生态系统之一，探明生态系统服务时空变化及权衡与协同关系，对区域生态治理决策和增进民生福祉具有重要意义。基于当量因子法、相关系数及空间自相关等方法，定量分析了2000—2020年石林生态系统服务的时空演变及权衡与协同关系。结果表明：(1)石林生态系统服务价值由2000年的20.47亿元持续增长至2020年的21.82亿元，增幅为6.60%,生态系统服务空间分布格局较为稳定，高等级区主要分布在水域地区以及植被覆盖较高的丘陵山区，低等级区集中分布在建设用地相对集中和岩溶石漠化严重的区域；(2)各土地利用类型生态系统服务价值敏感性指数均小于1,表明石林生态系统服务价值对修订后的生态服务价值系数缺乏弹性，研究结果可信；(3)研究期内，协同关系是石林生态系统服务的主导关系，协同率为68.60%,权衡关系主要存在于食物生产、维持养分循环与其他子系统关系中，权衡率达29.75%;(4)数量上，4种生态系统服务类型均存在显著的空间正向自相关，空间上，不同生态系统服务对权衡与协同关系异质性显著。研究结果可为石林优化国土空间格局及生态保护与修复提供参考依据。

| Abstract: | The karst area is one of the most fragile natural ecosystems on the earth. To clarify the temporal and spatial changes of ecosystem services and the trade-offs synergy is of great significance to the decision-making of ecological governance in this area and the improvement of people's livelihood and well-being. Based on the equivalent factor method, correlation coefficient and spatial autocorrelation, the spatial and temporal evolution of stone forest ecosystem services from 2000 to 2020 and the trade-off synergy relationship were quantitatively analyzed. The results showed that:(1)the value of ecosystem services continued to increase from 2.047 billion in 2000 to 2.182 billion in 2020, with an increase rate of 6.60%; the spatial distribution pattern of ecosystem services was relatively stable; the high-grade areas mainly distributed in water areas and hilly and mountainous areas with high vegetation coverage, and the low-grade areas concentrated in areas with relatively concentrated construction land and serious karst rocky desertification;(2)the ecosystem service value sensitivity index of each land use type was less than 1, indicating that the stone forest ecosystem service value was inelastic to the revised ecological service value coefficient, and the research results were credible;(3)during the study period, the synergy relationship was the dominant relationship between stone forest ecosystem services, with a synergy rate of 68.60%; the trade-off relationship mainly existed in the relationships between food production, maintenance of nutrient circulation and other subsystems, with a trade-off rate of 29.75%;(4)quantitatively, the four types of ecosystem services all had significant spatial positive autocorrelation, and spatially, the trade-offs and synergy between different ecosystem service pairs were significantly heterogeneous. These research results can provide a reference for Shilin to optimize the spatial pattern of the land and provide a reference for ecological protection and restoration. |
