Impacts of traffic accessibility on ecosystem services: An integrated spatial approach

The continuous degradation of ecosystem services is an important challenge faced by the world. Improvements in transportation infrastructure have had substantial impacts on economic development and services. Exploring influence traffic accessibility can delay or stop their deterioration; however, studies its impact are lacking. This study addresses this gap analysing using integrated spatial regression approach based evaluation value (ESV) Middle Reaches Yangtze River Urban Agglomeration (MRYRUA) China. results indicated that ESV MRYRUA continuously decreased during period, average plain areas, areas surrounding core cities, along main routes was significantly lower than mountainous areas. Traffic continued to increase high-value centred Wuhan, Changsha, Nanchang, Yichang were radially distributed. global bivariate autocorrelation coefficient between negative. exhibited significant dependence heterogeneity. Spatial also proved there a negative association accessibility, scale effects evident. findings policy implications for future ecological protection planning.
