摘　　要：由于我国现存统计制度的原因 ,区域经济统计数据具有基于行政地域单元汇总的特性 ,这一特性对城市GIS中空间数据和统计数据的结合以及区域和城市规划管理工作中定位性研究的分析结果产生影响 .针对以上方面并结合宁波有关实证研究 ,对GIS中区域经济统计数据的特征、数据处理、应用模型空间分析等诸多问题进行了探讨 .Because of some existing problems in the statistical system of China, many kinds of social and economic census data are aggregated data on administration regions. Such aggregated data cannot be applied directly to the individual object of study. For any set of individuals, there is a wide rang of possible ways of aggregation producing different results. If comparative quantitative study of GIS spatial model is undertaken, those the results may become invalid. The spatial analysis of social-economic census data and a cartographic applied model approach for such spatial analysis are discussed. The urban population forecast and the urban system dynamic simulation of Ningbon city is presented as a case study.
