环武夷山国家公园景观格局与生境质量的时空动态变化及空间关联分析

在中国国家公园体制建设背景下，统筹周边区域发展与生态保护具有重要意义。目前，尚缺少有关国家公园周边区域生境质量变化及其与景观格局破碎化关系的研究。以武夷山国家公园周边县市为研究区域，基于In VEST模型和Fragstats分析近40年(1980—2020年)生境质量和景观格局的时空演变，利用双变量空间自相关分析二者的空间关联特征。结果表明：1)近40年研究区域生境质量较好，整体呈下降趋势但幅度较小，平均值从0.861下降至0.845;2)近40年研究区域景观格局指数变化小但波动较大，建阳区的景观格局破碎化最为显著；3)研究区域景观格局与生境质量具有显著空间关联，LPI、CONTAG与生境质量呈显著正相关，PD、LSI、SHEI与生境质量呈显著负相关；4)研究区域城镇中心的景观破碎显著、生境质量较低；武夷山脉附近景观连通性较好、生境质量较高。解析了武夷山国家公园周边区域景观格局与生境质量的时空动态变化及空间关系，可为国家公园周边区域规划优化提供技术指导。

Spatial and Temporal Dynamics and SpatialCorrelation Analysis of Landscape Pattern andHabitat Quality Surrounding Wuyishan National Park

In the context of China''s national park systemdevelopment, it is of great significance to coordinate thedevelopment and ecological protection in the surrounding areas.Currently, there is a lack of research on habitat quality changeand its relation to landscape pattern fragmentation in the areassurrounding national parks. The counties and cities aroundWuyishan National Park were taken as the study area, and thespatial and temporal evolution of habitat quality and landscapepattern in the past 40 years (1980-2020) were analyzed based onInVEST model and Fragstats. In addition, the spatial correlationcharacteristics between landscape pattern and changes in habitatquality were analyzed by bivariate spatial autocorrelation. Theresults showed that, 1) the habitat quality in the study area wasbetter in the past 40 years, and the overall trend of decline wassmall, with the average value of habitat quality decreasing from0.861 to 0.845; 2) the landscape pattern indicators in the studyarea had small changes in the past 40 years, but fluctuations werelarge, and the fragmentation of the landscape pattern was the mostsignificant in Jianyang District; 3) there was a significant spatialcorrelation between the landscape pattern and habitat quality inthe study area. LPI and CONTAG were significantly positivelycorrelated with habitat quality, while PD, LSI and SHEI weresignificantly negatively correlated with habitat quality; 4) thelandscape fragmentation in the town centers of the study area wassignificant, and the habitat quality was low; the connectivity of thelandscape near Wuyi Mountain Range was better, and the habitatquality was high. The study analyzed the spatial and temporaldynamics and spatial relationship between landscape pattern andhabitat quality in the surrounding area of Wuyishan National Park,which could provide technical guidance for the optimization of theprotection and development planning of the surrounding areas ofnational parks.
