Coordination And Spatial Effect Analysis Of Urbanization And Ecosystem Services Based On Grid In Shanxi Province

In order to deeply explore the driving factors and spatial spillover effects of the coupling and coordination of urbanization and ecosystem services,this paper takes Shanxi Province as the research object,takes the four years of 2000,2005,2010 and2018 as the time nodes,studies the temporal and spatial evolution characteristics of urbanization and ecosystem services based on the grid scale,establishes the coupling and coordination degree model,and explores the degree and law of the coordinated development of the two,This paper discusses the agglomeration and evolution characteristics of its spatial distribution from the global and local spatial correlation,fully considers the fact of spatial spillover,and deeply explores the main factors affecting the coupling coordination degree of the two from the two aspects of nature and social economy,which provides a certain theoretical basis for the coordinated development of human land relations in ecologically fragile areas in China,and puts forward reasonable countermeasures and suggestions for the formulation of relevant policies.The results show that the overall value of ecosystem services in Shanxi Province showed a downward trend from 2000 to 2018,and the comprehensive level of urbanization was significantly improved,but the overall level was low.The coupling and coordinated development stage of urbanization and ecosystem services in the study area has realized the evolution trend of "serious imbalance-moderate imbalance-mild imbalance".During the study period,it is mainly moderate imbalance,and the global autocorrelation agglomeration trend of coupling and coordination between the two is gradually weakened.Spatially,it presents a distribution pattern with Taiyuan Basin as the core,higher in the middle,South and north of the region,and lower in the southwest and northwest.Among the direct spillover effects of influencing factors,per capita GDP,biological abundance index,NDVI and soil erosion index showed significant positive spillover,while human disturbance index,multi-year average temperature,proportion of secondary and tertiary industries and slope showed significant negative spillover;In the indirect spillover effect,human disturbance index,per capita GDP and NDVI showed significant positive spillover,while the proportion of secondary and tertiary industries and soil erosion modulus showed significant negative spillover;The results of spatial Doberman model show that the positive spillover effect of the coupling coordination degree of urbanization and ecosystem services is very obvious.This spatial effect shows that the coupling coordination degree of the study area is holistic and unstable,which makes each region lose its enthusiasm for environmental protection.
