江西省生态系统服务价值时空演变及驱动因素
Spatial and Temporal Evolution of the Value of Ecosystem Services and Drivers in Jiangxi Province
摘要
Abstract
In order to investigate the spatial and temporal evolution of ecosystem service value(ESV)and its influencing factors in Jiangxi Province,we constructed a land-use transfer matrix based on three periods of land-use data in Jiangxi Province in 2000,2010 and 2020,calculated the ESV by using the equivalent factor method,and introduced a geographically weighted regression(GWR)model to analyse the degree of influence of the key driving factors on spatial and temporal evolution of ESV in Jiangxi Province.The results showed that:(1)the main land use types in Jiangxi Province from 2000 to 2020 were forest land and arable land,and the land use transfer mainly consists of the conversion of arable land and forest land into construction land,and the mutual conversion of forest land and grassland.(2)The ESV of Jiangxi Province decreased from 439.088 billion yuan to 438.990 billion yuan from 2000 to 2020,and the spatial heterogeneity was significant.(3)Mean annual precipitation,elevation,per capita GDP,urbanisa-tion rate,distance from railway,distance from road were the key driving factors affecting the change of ESV.The influence of mean annual precipitation on ESV exhibits the characteristics of decreasing from north to south,and transitioning from positive to negative values,elevation,urbanisation rate,per capita GDP negatively affected ESV,and the distance from railway,distance from road posi-tively affected ESV.In conclusion,land use change is the direct cause of the change of ESV in Jiangxi Province,and the increase of construction land occupies a large amount of forest land and unused land,which leads to the decrease of ecosystem service value.In the future,we should control the scale of the expansion of construction land,and ensure the mutual balance status among the various categories,in order to synergistically promote the economic and social development and ecological and environmental protection.关键词
