旅游城镇化格局与生态系统服务的时空关联分析——以武夷山市为例

Analysis of spatiotemporal correlation between tourism urbanization pattern and ecosystem services——Taking Wuyishan City as an example

以典型旅游城市武夷山市为例,在分析城镇化格局、碳存储服务与土壤保持服务时空变化格局的基础上,采用双变量空间自相关等方法探索武夷山市旅游城镇化格局与生态系统服务之间的时空关联。研究表明:(1)2000—2010年武夷山市旅游城镇化进程发展迅速,陆地表层人类活动由3.79%升至5.05%,2010—2020年城镇化进程放缓,2020年陆地表层人类活动仅为5.33%;空间分异明显。(2)2000—2020年,碳存储服务呈下降趋势,土壤保持服务价值总量呈上升趋势,由2000年的26.38106 t升至2020年的45.26106 t。(3)陆地表层人类活动与碳存储服务之间存在负相关关系,而陆地表层人类活动与土壤保持服务存在正相关关系。旅游城镇化格局与碳存储和土壤保持2种生态系统服务之间呈现显著的时空关联特征。

Taking Wuyishan City as a typical tourist city,based on the analysis of the spatial and temporal change pattern of urbanization pattern,carbon storage services and soil conservation services,this paper explored the spatial and temporal relationship between tourism urbanization pattern and ecosystem services in Wuyishan City by using bivariate spatial autocorrelation and other methods.The research showed that:(1)From 2000 to 2010,the process of tourism urbanization in Wuyishan City developed rapidly,and the human activities on the land surface increased from 3.79% to 5.05%.The urbanization process slowed down from 2010 to 2020,and the human activities on the land surface only reached 5.33% in 2020;Significant spatial differentiation.(2)From 2000 to 2020,carbon storage services showed a downward trend,while the total value of soil conservation services showed an upward trend,increasing from 26.38106 t in 2000 to 45.26106 t in 2020.(3)There was a negative correlation between human activities on the surface of land and carbon storage services,There was a positive correlation between human activities on the surface of land and soil conservation services.There was a significant spatiotemporal correlation between the pattern of tourism urbanization and the two ecosystem services of carbon storage and soil conservation.
