随着中国经济发展和居民生活水平的提升,超重和肥胖问题开始显现,严重影响到居民的身体健康。基于中国家庭追踪调查的全国抽样数据,采用结构方程模型检验社区建成环境对居民个体超重的影响。研究发现,控制社会经济属性后,提高社区人口密度或设施可达性、缩短居民到公交站距离,可以通过减少个体机动化出行倾向而间接降低超重的可能性,但对超重的直接效应及总效应为正。这一结论与西方发达国家的经验不同,因此制定健康政策需要...
当代西方教学和科研中常用的可视化工具主要有ArcGIS、QGIS、CHGIS、CartoDB、Worldmap、CBDB、GEPHI等数据库和软件。其中“中国历史地理信息系统”和“中国历代人物传记数据库”是由哈佛大学包弼德教授主持的项目,与中国的文史研究直接相关。利用上述数据库和软件,以汤显祖为例,可展示汤显祖行迹和活动地点、社会关系地理分布、社会关系点线表达等多种可视化效果图,给人以直观明了、耳...
