The definite spatial relationship between urban green space (UGS) and human activity intensity (HAI) is very import for urban planning and management, especially for ecological construction of big cities. Existing studies on the spatial relationship between UGS and HAI is not comprehensive for lacking quantitative analysis or mechanism analysis. In this study, through spatial mapping and spatial correlation analysis, we revealed the spatial correlation between UGS and HAI from the perspective of ecosystem service (ES) and developed a model which can process and analysis the whole urban UGS and HAI. Based on visible light image vegetation extraction technology and geographic information system (GIS) space analysis model, the model improved spatial precision and rationality. A case study of ChengDu City, China, further illustrated the adaptability of the model in typical cities. The results show that UGS coverage rate has reached 37.71%, while less than 27.49% UGS was used efficiently. Human living and catering consumption behaviour rely on UGS much, and the poor balance between several UGS’s ES and HAI should be highly valued. The findings of this study will be of practical value for allocating UGS and regulating population.
