Abstract: Based on the Gross Domestic Product (GDP) and 1 km×1 km land use data of 1980, 1990, 2000, and 2012, 2853 counties or districts of China, the rates of change in ecological service value (ESV) and GDP were calculated. Spatial analysis were performed in ArcGIS to examine coordinated development of ecological-economic system and its spatial variation and temporal change. The results are as follows. (1) Since 1980, county level GDP growth in China has been very rapid. The rate of GDP growth in China's southeast coastal area is higher than that in the central part, followed by counties in western China. (2) The total ecological service value of China increased from 85302.15 billion yuan in 1980 to 94876.82 billion yuan in 2012, with a 11.22% increase. Spatially, county level ESV is higher in northern and western counties, and lower in eastern counties. (3) The coordination between economic development and quality of the ecological -environment (EEH) has gradually improved. At the county level, EEH in northern China is better than that in western China followed by central and eastern counties. But the sustainable development challenges of the ecological-economic system is still high. The degree of spatial correlation of EEH is relatively stable. The development trend of coordination between socioeconomic development and ecological environment tend to be positive, but ecological-economic system coordination in different counties varies significantly. The results of this study suggest that the regional economy of China's western counties should be further developed when efforts are made to protect the ecological environment of the region, while in China's central and eastern counties, greater attention should be paid to the protection of the ecological environment and ecological restoration, when the economy continues to grow. Achieving sound and fast economic development and maintaining ecological integrity is a balancing act that requires much greater effort.

Key words: ecological service value, ecological-economic harmony, ecological-economic system, regional economy, spatial evolation
