1、外文资料 Urban planning and management information systems analysis and design based on GIS In 2000 October the Central Committee of Communist Party of China fifteen 5 in plenary meeting passes the CPC Central Committee on national economic and Social Development tenth five year plan suggestion, put for

2、ward clearly to want to accelerate national economy and social informatization pace, advance national economy and social informatization to be put in first place. In 2001March, the ninth session of the National Peoples Congress approved by the fourth meeting of the peoples Republic of China national

3、 economy and social development Tenth Five Year Plan, the realization of information also made the following provisions: according to the application of dominant, market oriented, network construction, resources sharing, technology innovation, competition and opening up the development train of thou

4、ght, realize our country information industry hard span type develops, accelerate advance informatization, improve the information industry the proportion in national economy. City planning, construction, management and services of digital engineering ( referred to as the city of Digital Engineering

5、 ) has also been through the Ministry of science and technology new and high division of acceptance by experts. By the international and domestic situation is not difficult to see that the city planning information and the importance of the obtained good opportunity. From the economic and technical

6、point of view, the rapid development of science and technology and the social economy make a spurt of progress of city planning management concept, methods and means raised new taller requirement. By means of modern science and technology especially the information means to improve city planning and

7、 management, improve the level of the city planning has become the inevitable trend of history. On the political and economic background, city planning and management information system of this discipline emerge as the times require. China city planning management information technology application

8、start sub nineteen eighties later, in Changzhou, Luoyang and Shashi three city world bank loan for city planning and management information system construction for mark. After 15 years of development, city planning and management industry of China has become the most influential OIS application, dev

9、elopment rate is the rapiddest, achieved practical results most industry. The application of GIS for city planning and management provides a fast and efficient means of acquiring information, information analysis method, provides a new planning management technology, new plan, new forms of public pa

10、rticipation and public supervision mechanism. But we can see, at present there are some problems in city planning. Many city more use of a developing system, resulting in a lot of manpower and resources to repeat investment, also shows that the city planning information standardization degree is rel

11、atively low； a lot of city planning management information system office automation is more significant than, decision support function is weak, although the city planning and management information system presents from the document to text based change, but its manifestations are still in need of f

12、urther research and improve； public supervision implement is not common, this and government affairs and resources sharing is the target of a considerable gap. Therefore, based on the GIS city planning management information system research and application of the subject still need further reflectio

13、n and exploration, and strive in the existing system design based on the way of reasonable summary, follow industry information standardization, enhance the role of decision support, will form is optimized further, and further implementation of public participation and supervision. Based on the anal

14、ysis of existing relevant systems on the basis of inadequate, after a detailed investigation and research, urban planning and management information system will be designed for three-tier structure system, under the LAN using C / S mode architecture. Related functions for the system designed in acco

15、rdance with the requirements of the architecture design of the functional relationships between the modules. Analysis of the relevant interface and design, data storage solutions proposed. The design for small and medium urban planning information system provides a viable building program. I INTRODU

16、CTION At present, many small cities have developed their own planning and management information systems, management information systems which have their own characteristics. According to its development platform, can be divided into three categories: First, the office automation management informat

17、ion systems based on the existing database management software, such systems can only be a simple document information storage, information, operation, and graphic information can do nothing, No GIS (geographic information system) functions. Clearly, such systems can not meet the Planning Boards bus

18、iness office and information management requirements, the system lacks integrity. Another single GIS platform as the basis for the development, but generally more difficult this way, the development cycle is longer1. As a result, many developers choose to develop a third way, namely, cross-platform

19、development - MIS capabilities in database management software platform, GIS functionality in GIS platform development. This will be a complete office management information systems planning artificial division into two parts, between the two parts of the switching frequency, not only easily lead to

20、 system instability, a waste of valuable computer resources and will increase the system overhead and costs , resulting insubstantial increase in the users development costs2.Since a system using two platforms, but also limits the system scalability, maintainability of the system will also be greatl

21、y reduced. Comparison of three methods based on the development, as well as a large number of practical engineering experience in project development, the key to this design is truly the first integrated graphics, especially in the deep data integration to achieve integrated graphics； second is to h

22、ow to adopt a flexible, adaptive, tool-based management； addition is to ensure system scalability, as set multiple functional interface to realize the special needs of the user service customization and with the outside world the data import and export data3. Thus, the OA office and closely integrat

23、ed GIS technology in one system, speed, scalability, availability and maintainability have been very good guarantee. II BUSINESS PLANNING AND MANAGEMENT OF INFORMATION SYSTEMS This article will assist small and medium urban planning and management of business functions can be divided into Planning a

24、nd Management, file management and administrative office, auxiliary management, sales chart and technical services, information dissemination of six parts. All the features of the system are closely around the Planning and Management Business expand, each business function is another link between th

25、e interaction. III SYSTEM ARCHITECTURE DESIGN Urban planning and management information system is mainly a business process, do the text focus on process control management system to be divided into three structural system, the use of the LAN under the C / S mode architecture. Manage use of specialized GIS software and components, maintenance of spatial data
