Abstract

Abstract: Based on the GlobeLand30 surface cover data of Guangzhou City in 2020, the spatial distribution characteristics of the ecosystem service value of various districts in Guangzhou City were analyzed by using the value equivalent method after coefficient correction. An economic-ecosystem service value index （GDP-ESV） based on the integration of social economic data was proposed to analyze the development contradiction between the ecosystem service value and the social economy in each district of Guangzhou City. The results showed that the total value of ecosystem service functions in Guangzhou City in 2020 was 34.8 billion yuan, of which waters and forest land were the main contributors. The value of ecosystem services in Guangzhou City had a significant positive spatial correlation （P<0.05）. The high-value clustering areas were mainly concentrated in the northern woodland area of Conghua District and the Pearl River estuary in the east of Panyu District. The low-value gathering areas were mainly concentrated in the agricultural areas of Conghua District, Zengcheng District and Huadu District. The GDP-ESV index of each district in Guangzhou was quite different. The GDP-ESV indexes of Yuexiu District and Tianhe District were 3 156.36 and 1 882.96, respectively, indicating that there was a serious conflict between the socio-economic development and ecosystem services value in these two districts. These two districts should take into account the actual situation of the area, increase the value of ecosystem services, and strengthen the utilization of urban space. The conflicts between socio-economic development and ecosystem service value in Conghua District and Zengcheng District were the smallest, and the GDP-ESV index was 4.32 and 14.78 respectively. These two districts should properly carry out eco-tourism to promote the preservation and appreciation of the value of ecosystem services.

Key words: GlobeLand30, ecosystem service value, social economy, synergistic development, spatial autocorrelation, GDP-ESV, Guangzhou City
