摘要
以多期遥感影像和地理国情普查及监测成果为基础,基于遥感和GIS平台,提取道路网络矢量数据。利用ArcGIS密度分析工具生成道路网络密度图,分析两江新区2010年设立以来路网空间格局变化特征。基于可达性计算方法以及分级统计分析方法,分析道路网络与机场、港口、医院、学校等基础公共服务设施的匹配程度,探求新区路网空间格局变化趋势及其存在问题,为新区规划提供建议。
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.
