Research on the characteristics and driving factors of ecosystem service value in Northeast China
It is of great significance to explore the changes of ecosystem service value(ESV)and its driving force in Northeast China for the healthy development of regional economy and eco-environment.Based on the five-period remote sensing data in Northeast China from 2000 to 2018,the ESV coefficient method,geographic detector and GWR model were used to analyze the changes and driving forces of ESV in Northeast China.The results showed that:1)in the past 18 years,the ESV in Northeast China lost 98.27 billion yuan.Forest land ESV was the main component source of the ESV,and its core functions were hydrological regulation and climate regulation.2)The ESV was spatially high in the middle and low at both ends.High-value areas and sub-high-value areas were widely distributed.3)The interaction of economic and social factors had the greatest impact on the ESV.4)The influence of the leading driving factors on the ESV had obvious spatial differences.The action intensity of population density decreased from north to south,action intensity of the GDP had obvious spatial agglomeration,and action intensity of the average annual precipitation decreased from east to west as a whole.The research results can provide some scientific references for the scientific formulation of eco-environmental protection policies in Northeast China.
