Evaluation Implementation for Accessibility of Urban Public Green Space Based on ArcGIS Engine

摘要

According to the geographical characteristics of urban public green space, the paper analyzes the factors and indexes which influence accessibility evaluation. Combining analysis functions of GIS desktop software, the paper proposes the accessibility evaluation method of urban public green space (UPGS) based on the accessibility path analysis, and then implements the function of accessibility path analysis to UPGS using ArcGIS Engine technology. This method can not only evaluate the existing UPGS, but also help the unestablished park to determine the location, and plays a certain decision-making role.
