中文摘要	为研究人类活动对喀斯特山区生态系统服务产生的影响,以滇东南典型石漠化区广南县为研究区,选取6种生态系统服务从空间上与石漠化强度进行对比,并运用相关系数分析其权衡协同关系,通过热点图分析了其提供能力强弱的时空变化。结果表明:(1)20002018年,研究区食物供给和文化服务与石漠化程度空间分布基本无相关性,而土壤保持、固碳、产水量和生境服务与其分布基本呈负相关关系;(2)20002018年,研究区生境支持固碳和土壤保持固碳等呈协同关系,而产水量土壤保持和产水量生境支持等呈权衡关系;(3)20002018年,研究区热点区占比为6类>5类>0类>1类>2类>3类>4类;空间上,0类为生态脆弱区且为无热点区,分布在中部和西南部的石漠化中度区域;6类为供给能力最高的区域,主要分布在北部及东北部。总之,石漠化区生态系统服务功能较无石漠化区低且基本为无热点区,但权衡协同关系较为显著。因此,应继续采取相应的生态恢复措施。
英文摘要	In order to study the impact of human activities on ecosystem services in karst mountainous areas, Guangnan County,a typical rocky desertification area in southeastern Yunnan Province,was selected as the research area.Six ecosystem services were selected for spatial comparison with rocky desertification intensity,and correlation coefficients were used to analyze its trade-off and synergy relationship,and the heat maps were used to analyze temporal and spatial changes of its providing capabilities.The results show that: (1)from 2000to 2018,food supply and cultural services in the study area were basically not related to the spatial distribution of rocky desertification,while soil conservation,carbon sequestration,water production,and habitat services were basically negatively related to their distribution;(2)from 2000to 2018,the study area had a synergistic relationship between habitat support-carbon sequestration and soil conservation-carbon sequestration,while water production-soil conservation and water production-habitat support had the trade-off relationship;(3)from 2000to 2018,the proportion of hotspots in the study area decreased in the order:category 6>category 5>category 0 > category 1>category 2>category 3>category 4;spatially,category 0was the ecologically fragile area with no hotspots,and distributed in the middle and southwestern rocky desertification areas, category 6was the area with the highest supply capacity,mainly distributed in the north and northeast. Corresponding ecological restoration measures should be continued.Priority protection is required.
