摘要
[目的]建立兼顾区域本底差异的生态补偿模型,进一步明确京津冀生态补偿时空分异格局及其主导驱动因子,为政府部门制定环境保护与宏观经济政策提供参考。[方法]基于修正碳赤字,利用模型构建、空间相关性分析与地理探测器技术等方法构建了合理的生态补偿框架,分析和研究了2007—2020年的京津冀县域生态补偿的时空变异格局、空间自相关性、驱动因子排序和交互作用等内容。[结果]①京津冀县域2007—2020年碳排放量呈现“先增后减”的变化趋势,碳吸收量大体呈现持续增加的变化趋势。②修正前的京津冀县域碳赤字呈现东、南、西部高,而北部较低的U形格局,而修正后的碳赤字由于兼顾了区域间本底差异,在时空分布上更加均匀。③生态补偿额度冷点区域基本分布在京津冀东北部,热点区域分布在京津冀西南部,两者之间存在个别冷热点区域,整体呈现热点区域向东北方向移动,冷点显著区域向西南方向移动的趋势。④不同年份内影响生态补偿额变化的主要因子不同,2007,2012,2017和2020年这4a中影响京津冀县域生态补偿变化的主导影响因子分别为第三产业产值、财政收入、第二产业产值和人均生产总值;不同年份导致生态补偿变化的因素交互影响力不同,交互作用表现出先互相减弱后互相增强的反复效应。[结论]兼顾区域本底差异的生态补偿模型,对京津冀生态补偿时空分异格局及其主导驱动因子的分析具有一定的公平性,可为政府部门制定环境保护与宏观经济政策提供更精准的指导和建议。
[Objective]An ecological compensation model taking into account regional background differences was established to further clarify the spatial and temporal differentiation pattern of ecological compensation and its leading driving factors in the Beijing-Tianjin-Hebei region,in order to provide to a reference for government departments to formulate environmental protection and macroeconomic policies.[Methods]Based on a modified carbon deficit,a reasonable ecological compensation framework was constructed using model construction,spatial correlation analysis,and GeoDetector technology,etc.The spatial and temporal variability pattern,spatial autocorrelation,driver ranking,and interaction of ecological compensation in the Beijing-Tianjin-Hebei region during the period of 2007 to 2020 were analyzed and investigated.[Results]①Carbon emissions in the Beijing-Tianjin-Hebei region from 2007 to 2020 showed a pattern of"increasing and then decreasing"over time,and carbon sequestration generally showed a trend of continuous increase.②The carbon deficit in the Beijing-Tianjin-Hebei region before the amendment showed a U-shaped pattern with high carbon deficits in the east,south,and west,and low carbon deficits in the north.After the amendment,the carbon deficits were higher in the east,south,and west due to low carbon deficits in the north.After the amendment,the carbon deficits were more evenly distributed in space and time due to the local differences between regions.③The cold spot area of the ecological compensation amount was basically located in the Northeast Beijing-Tianjin-Hebei region,and the hot spot area was located in the Southwest Beijing-Tianjin-Hebei region.There were individual cold and hot spot areas between the two areas.The hot spot area was moving to the northeast,while the cold spot area was moving towards the southwest.④The main factors affecting the change of ecological compensation amount were different in different years,and the main factors affecting the change of the ecological compensation a
