- Abstract:

In order to explore the impact of urban expansion on ecosystem service values, the spatial and temporal evolution pattern of urban expansion intensity and ecosystem service values in the Yangtze River Economic Belt and its correlation were analyzed using the hot spot analysis method and the GTWR(geographically and temporally weighted regression)model. The results show that: during the past 15 years, the urban area of the Yangtze River Economic Belt had been expanding continuously, with the urban expansion intensity of 0.02% each year; the hot spots had been transiting from the southeast of the Yangtze River Delta to its central and northern parts, and gradually covered the whole Yangtze River Delta; from 2000 to 2015, the total value of ecosystem services had decreased by 0.27% in the Yangtze River Economic Belt, among which the hot spots of provision service values, regulation service values, support service values and total service values decline were concentrated in the Yangtze River Delta, while the hot spots of cultural service values decline distributed in some areas in Zhejiang Province and Jiangxi Province; the process of urban expansion had no significant effect on cultural service values, but it had significant negative effects on provision service values, regulation service values, support service values and total service values. The negative effects of urban expansion on ecosystem service values had the characteristics of spatial and temporal heterogeneity. Therefore, differentiated management mode should be adopted in the ecological protection of the Yangtze River Economic Belt.
