“…In addition, the spatial spillover effects of ecosystem services are innovatively revealed according to ecosystem service flow conduction mechanisms.ResultsResearch results are summarized as follows. 1) During the 11 years from the 2010 to 2020, the growth of carbon dioxide emissions in the Shanghai Metropolitan Area gradually slowed down, while the net primary productivity of vegetation continued to increase, and the areas with high carbon emissions and high carbon sinks were partially overlapped; in addition, the net carbon sink efficiency of some core nodes, such as Shanghai City, maintained a steady improvement, effectively driving neighboring cities to reduce carbon emissions and increase carbon sinks; meanwhile, the areas with improved net carbon sink efficiency have some similar characteristics and can be divided into 2 types: areas with high production value, high carbon emissions, and high carbon sinks, and those with medium-high production value, low carbon emissions, and medium-high carbon sinks. 2) The four ecosystem services have significant spatial heterogeneity and relatively stable changes over the 11-year period, with the high values mainly distributed in the southwestern part of the area with high vegetation cover and the area around the
Taihu Lake with concentrated water resources, while the low values mainly distributed in the concentrated urban construction areas and near the regional traffic arteries, and the total amount of the four ecosystem services has shown fluctuating characteristics. 3) Regarding the spatial decomposition effects of ecosystem services on net carbon sink efficiency, there are differences in the coefficients, directions and significance of the spatial effects of different ecosystem services. …”
