"Megacities have placed greater demands on quantitative indicators for community public spaces in spatial planning. However, in the planning of living circle of traditional communities, people living in the community have not been accurately evaluated and differentiated for their needs. Besides, the lack of overall evaluation and pre-judgment of user population may lead to problems such as spatial homogeneity and low efficiency of use. Based on the context above, this paper promotes to provide a refined quantitative evaluation basis for community renewal. Firstly, by comparing the measured value and target value of community public space use under different conditions and building a quantitative system of evaluation-optimal selection-design, this paper explores an evaluation-design path including spatial performance evaluation, spatial attributes matching, crowd-spatial behavioural characteristics, differential layout and precise design. Secondly, this research takes the public space of an old community in Guangzhou as an example to measure and analyse the overall coverage and walking convenience of high-usage and vulnerable subjects such as the elderly, women of child-bearing age and young children, and uses the data to construct their portraits and activity maps in public spaces. Finally, this paper provides evaluation methods and design responses for equitable and inclusive community renewal." Keywords: spatial equity, four standards and four real spatial data, spatial performance evaluation user portraits, activity map.
