| Abstract: | Based on the multi-time remote sensing imagery and the national geographic surveys and monitoring data,we attained land use vector data through image interpretation with the aid of a remote sensing and GIS platform.The density map was used to analyze the characteristics of spatial pattern changes of Liangjiang New Area road network since 2010.The accessibility calculation and statistical analysis methods were used to analysis the road network match basic public service facilities such as airports,ports,hospitals,schools.Explore the changing trend and existing problems of the road network in Liangjiang new district to provide suggestions. |
