GIS正在从专业技术领域走向社会化地理信息服务，不同领域不同层次用户对地理信息表达提出了多层次的服务需求，空间数据LOD (Level of Detail)表达则是实现该需求的关键技术策略。
1990年代中国文化地理学学者多研究中国省区文化地理，进入2000年代中国文化地理学学者对社区文化的研究逐渐增多。然而小尺度区域的文化如何嵌套在大区域的文化中是一个尚未解决的学科问题。从认识文化空间的学科意义上看，如果回答了这个问题，那么就意味着大区域文化地理格局与小区域的文化地理格局之间可以升尺度和降尺度。从社会实践意义上看，如果回答了这个问题，则可以将社区的文化建议与城市、与省区的文化建设有机

利用DMSP和CHAMP卫星全球协同观测数据,研究了不同磁扰活动水平下亚极光区极化流(Subauroral Polarization Streams,SAPS)与约400km高度热层纬向风随季节的变化规律及其相互之间的关系。研究发现：SAPS和纬向风的峰值速度出现在同一纬度,然而两者的峰值速度表现出明显相反的季节变化,SAPS冬季高于夏季,纬向风则夏季高于冬季,南北半球以及不同磁扰活动水平下皆为如
