【摘要】：人口地理信息系统既是人口地理研究成果的有效宣传载体，也是应对自然灾害和公共突发事件的科技支撑平台。人口问题是制约区域可持续发展的重大问题之一，统筹解决人口问题，关系国家稳定、经济发展、人民生活水平，因此，无论是发达国家，还是发展中国家，均围绕人口普查或户籍管理，积极开发各自的人口地理信息系统。分析国内以往开发的人口地理信息系统，大多数存在着人口数据更新时间长，人口动态信息更新频率低，基础地理信息、专题地理信息、经济社会统计数据等不统一、不一致，且系统建设多依赖于技术驱动等问题。针对这些问题，文章从用户与角色、系统架构、系统组成三个方面探讨了构建人口GIS的关键因素，并基于河北省全员人口数据库，使用Flex和ArcGIS Server，以河北省为例，构建了河北省人口地理信息系统。该系统实现了人口专题图的查询、浏览，实现了对地震、洪水等重大自然灾害的人口应急响应功能。本文从软硬件组成、数据处理和组织、地图生产和服务发布、系统功能及实现、系统部署等方面详细介绍了河北省人口地理信息系统的设计与开发过程。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，需要采用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，基于REST接口，，利用ArcGIS For FlexAPI函数，开发了WebGIS程序，解决了浏览器兼容性问题，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。随着WebGIS的发展，二维人口GIS已经不能满足用户的视觉和体验需求，三维GIS是人口GIS未来发展方向之一，本文使用ArcGlobe和CityEngine软件对三维人口GIS进行初步探索，实现了人口信息三维宏观展示和微观展示，虽然尚未达到理想效果，但是为后期三维人口GIS的研究奠定了基础。
[Abstract]:Population Geographic Information system (PGIS) is not only an effective carrier of population-geography research, but also a scientific and technological support platform to deal with natural disasters and public emergencies. The population problem is one of the major problems that restrict the sustainable development of the region. It concerns the stability of the country, the economic development and the living standard of the people. Therefore, whether it is developed or developing countries, All around census or household registration management, actively develop their own population geographic information system. Analyzing the population geographic information system developed in the past in China, most of the population data update time is long, population dynamic information update frequency is low, basic geographic information, thematic geographic information, economic and social statistical data and so on are not uniform, inconsistent, etc. And the system construction depends on the technology drive and so on. Aiming at these problems, this paper discusses the key factors of constructing population GIS from three aspects: user and role, system structure and system composition. Based on the population database of Hebei Province, using Flex and ArcGIS Server, taking Hebei Province as an example, The population geographic information system of Hebei Province is constructed. The system can query, browse and respond to major natural disasters such as earthquakes and floods. This paper introduces the design and development process of Hebei population Geographic Information system in detail from the aspects of software and hardware composition, data processing and organization, map production and service release, system function and realization, system deployment and so on. The research shows that the population GIS needs to face both data producers and data consumers, and needs to adopt the B / S and C / S hybrid architecture. In the C / S architecture of the system, the mature GIS desktop system is used directly, which not only satisfies the population and geographical data production, 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 time and the results can be released in time. In the part of B / S architecture of the system, using Flex, based on rest interface and using ArcGIS for Flex API function, the WebGIS program is developed, which solves the problem of 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. With the development of WebGIS, two-dimensional population GIS can not meet the needs of users' vision and experience. Three-dimensional GIS is one of the future development directions of population GIS. This paper uses ArcGlobe and City engine software to explore the three-dimensional population GIS. The 3D macro and micro display of population information has been realized. Although it has not yet achieved the ideal effect, it has laid a foundation for the research of 3D population GIS in the later stage.
