Abstract
Urban park greenland is one of typical green open space. It is very important for the maintenance of urban ecological security and human health.

The results show that: 1) Municipal park account for 84.71%of total area of urban parks in center of Guangzhou. Its contagion index is 92.44. The landscape type and spatial pattern of urban park greenland are less reasonable. 2) Based GIS network analysis, only 22.35%of the study area and 44.67%of residents can easily access urban park greenland. The accessibility of park greenland and its service quality of Guangzhou centre area are not good enough. 3) The number and distribution are important factors influencing the accessibility and service quality of urban park greenland.关键词
