延河流域生态敏感性与景观格局空间自相关性
Spatial autocorrelation between ecological sensitivity and landscape pattern in the Yanhe River Basin
摘要
Abstract
To explore the distribution and intrinsic connections between ecological sensitivity and landscape pat-terns in the Yanhe River Basin,this study employed ArcGIS 10.8 and Fragstats 4.2 to analyze their spatial auto-correlation.The results demonstrated that(1)Ecological sensitivity in the Yanhe River Basin exhibits significant spatial variation.The extremely,moderately,and highly sensitive areas spanned 473.04 km2,1921.21 km2,and 1272.15 km2,accounting for 6.12％,24.87％,and 16.47％of the total area,respectively,and primarily consisting of water areas,forestlands,and cultivated lands.(2)The spatial autocorrelation between ecological sensitivity and land-scape pattern was significant.The number of patches(NP)and edge density(ED)were positively correlated with ecological sensitivity,indicating that higher landscape fragmentation in the Yanhe River Basin led to stronger eco-logical sensitivity.The largest patch index(LPI)and average patch area(Area_Mp)were negatively correlated with ecological sensitivity.The implementation of forestry ecological projects such as converting farmland to for-ests(grassland),increased the proportion of large patches in the Yanhe River Basin,effectively reducing ecologi-cal sensitivity.Therefore,future ecological protection strategies for the Yanhe River Basin should consider the spatial autocorrelation pattern and tailor measures to different regions,thereby further enhancing ecological pro-tection and promoting high-quality development in the Basin.关键词
