不同格网尺度下生态系统服务价值空间分异及影响因素分析
Spatial difference of ecological services and its influencing factors under different scales
摘要
Abstract
[Objective]The aims of this study are to explore the scale effect of spatial differentiation of ecosystem service value,and to provide reference for ecological protection and economic development decision-making in the Qinling Mountains region.[Methods]The ecosystem service value of the Xi'an section of the Qinling Mountains in 2020 was calculated with the improved equivalent factor method at five grid scale levels:5 km,3 km,2 km,1 km,and 0.5 km.The spatial differentiation characteristics of ground average ESV at different scales was analyzed with the spatial autocorrelation analysis and cold hot spot analysis.The intensity of the influencing factors at various scales was quantitatively analyzed with geographic detectors.[Results](1)The overall distribution pattern of ground average ESV was low in the north and high in the south with small dispersion and large agglomeration,and the local ESV became more abundant,while the overall ESV decreased with the scale decreasing.(2)The 2-km scale was suitable for macro analysis and overall layout planning,while the 1-km scale was suitable for studying the impact of water changes on regional ESV.(3)The smaller the grid scale,the greater the internal differences among various influencing factors,resulting in a decrease in overall features,highlighting local feature differences,and enhancing spatial differentiation.(4)The transformation of land use caused by human activities significantly affected the value of regional ecosystem services,and the coupling effect of multiple factors significantly affected the spatial differentiation of regional average ESV.As the scale decreased,its impact weakened.[Conclusion]The ecological protection of the Xi'an section of the Qinling Mountains should focus on the transformation of regional land use nature.The policy of returning farmland to forests should be further strengthened,and the scale of construction land should be controlled.On the basis of considering ecological protection,economic development layout planning can be formulated.关键词
