Evaluation of Eco-economy Harmony and Spatial Evolution of the Urban Agglomeration Area in The Great Pearl River Delta

Based on the land use data of the study area during 1990 to 2016, the coordination between ecological environment and economy was estimated according to the ESV (ecosystem services value) and EEH (eco-economy harmony) index. The results showed that large amount of farmland and forests were changed to construction land in the study area, due to the rapid urbanization and industrialization. The ESV showed an overall downward trend, the ESV in per hectare was decreased from 1554,000Yuan to 14513,000Yuan. The economic development speed was decreased from 1990 to 2016, the area with high GDP growth rate is changed from the core area of the pearl river delta to the periphery area. The ecology-economy relation in the study area experienced a transformation of low grade coordination-low grade conflict -further conflict. Shenzhen, Dongguan, Huizhou, Jiangmen, the central city of Foshan and Guangzhou became the most high-grade conflict areas.
