- Abstract:
- Using Middle Yangtze River Economic Belt as the study area, based on the land use data, corrected ‘the equivalent value per unit area of ecosystem service in China’ proposed by XIE Gao-di, estimation of spatiotemporal change of ecosystem service value (ESV) was conducted. The results are shown as follows. During the period of 1990-2014, the ESV of Middle Yangtze River Economic Belt had increased 11.38 billion yuan, annual growing rate was 0.016%. The spatial distribution pattern of ESV presented as the order:mountainous > hilly > plains. The rising area of ESV concentrated in the south of Jianghan Plain and the west of Dongting Lake Plain, while the areas with decreasing ESV mainly distributed along the line of ‘Shishou-Yushui-Jiujiang’. Supply and support service value had deceased 2.81 billion yuan and 3.56 billion yuan, while accommodation service and cultural service values had increased 15.69 billion yuan and 2.06 billion yuan. The spatial distribution characteristics of supply, support, cultural service values were similar, and presented as the high values in the mountains and low value in the plain, while both the high and low values of accommodation service value concentrated in the plain. Four ecosystem service function values decreased along the line of ‘Shishou-Yushui-Jiujiang’, while spatial distribution of rising values was different, and presented as the accommodation and cultural value rise in the south of Jianghan Plain and the west of Dongting Lake Plain, support value rose in the southwest of Jianghan Plain, and the rise of supply service value was not obvious.
