- Abstract:

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 2000 to 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 2000 to 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 2000 to 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 0' was the ecologically fragile area with no hotspots, and distributed in the middle and southwestern rocky desertification areas, ‘category 6' was 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.
