【摘要】：围绕河北省全员人口数据库,开展了分布式人口地理信息系统的构建研究.研究表明,人口地理信息系统需同时面对数据生产者和数据消费者,必须采用B/S和C/S混合架构模式.在系统的C/S架构部分,直接使用成熟的GIS桌面系统,既满足了人口地理数据生产,也减轻了系统开发强度和难度,同时保证能及时开展各种复杂空间分析,及时进行成果发布;在系统的B/S架构部分,使用Flex语言,基于Rest接口,利用ArcGIS For Flex API函数,开发了WebGIS程序,解决了客户端浏览器兼容性问题,满足了用户对人口地理数据的消费行为.系统与全员人口数据库融合,突破了对人口普查和统计年鉴的刚性依赖,提高了人口个案信息和统计信息的时效性;系统与各厅局专题数据融合,拓展了人口宏观决策参与范围.实践证明,分布式人口地理信息系统已成为人口地理研究产、学、研一体化的工作平台,分布式是人口地理信息系统步入社会化驱动阶段的必由之路.
[Abstract]:Based on the whole population database of Hebei Province, the construction of distributed population Geographic Information system (DGIS) is studied. The research shows that the population GIS needs to face both data producers and data consumers, and must adopt the mixed architecture of B / S and C / S. In the C / S architecture of the system, the mature GIS desktop system is used directly, which not only satisfies the production of population and geographical data, but also reduces the intensity and difficulty of the system development. At the same time, it ensures that all kinds of complex spatial analysis can be carried out in a timely manner. Timely release of results; In the part of B / S architecture of the system, using Flex language, based on Rest interface and ArcGIS For Flex API function, the WebGIS program is developed, which solves the problem of client browser compatibility and satisfies the consumer behavior of population and geography data. The integration of the system and the whole population database breaks through the rigid dependence on census and statistical yearbook and improves the timeliness of population case information and statistical information. The system integrates with the thematic data of various departments and bureaux, and expands the scope of population macro decision-making. It has been proved by practice that distributed population Geographic Information system (DGIS) has become an integrated platform of population geography research, learning and research, and distributed is the only way for population Geographic Information system (DGIS) to enter the stage of socialized driving.
