Abstract: Integrating the basic theories of landscape ecology, the concept of equity of urban green space pattern is put forward to explore an equity assessment method oriented on human behavior scale. The authors choose Shenzhen as a case study, using the method of neighborhood analysis on ArcGIS platform, to assess the equity of urban green space pattern in four scenarios and carrying out discussions on its optimization strategy. The results show that: 1) spatial differentiation exists obviously in equity on urban green space in Shenzhen; 2) the big differences between absolute equity (E) and relative equity (E^*) on urban green space pattern indicate that the configuration of the residential land could affect the equity of urban green space pattern in some extent; 3) the different results under two behavior scales demonstrate that trip distance could impact the equity of urban green space pattern; 4) the equity assessment results could be used to guide the optimization of urban green space pattern and provide reference for urban green space system planning and management.

Key words: urban green space, pattern equity, behavior scale, the modifiable areal unit problem, pattern optimization
