In the light of the characteristics of information management of emergency prevention and control for severe epidemic disease, an emergency commanding platform for animal disease in Beijing was established, including overall layout, structure of technical system, function, database, and design and exploitation. In the paper, a series of critical techniques including operation flow pattern, logical frame for emergency disposal, and comprehensive decision-making model were researched. Application of seamless bonding technology for Flex controls and ArcObjects components in the system was proposed; some key issues including analysis of epidemic focus, determination of epidemic spot, epidemic area, threatened area, intersection blocking, epidemic monitoring, harmless disposal, disinfection, slaughter, emergency immunization and lifting of the blockade were resolved. Based on the platform, the aim of information and integration of emergency command for major animal disease in Beijing was achieved. The platform can provide timely and accurate information for comprehensive judgment of actual prevention and control situation and scientific decision-making, as well as fast and great support to emergency command for severe animal epidemic disease for Beijing.

随着天津市城市化进程的加快,城市建设中的水土流失问题日渐突出.根据<天津市城市总体规划>、<天津市城市防洪(潮)规划>与城市水土流失特点,从水土流失治理与预防监督角度出发,采用多种水土保持措施优化配置,综合规划,探讨了具有天津市特色的城市水土保持规划模式.

This paper described the currently instance of Beijing country renewable energy,and then suggested that Country Renewable Energy Management and Decision Support System of Beijing should be built.Based on the WebGIS technology,we studied about the system’s whole design,including database design and function design.

According to the requirements of quality and safety authentication and management of agricultural products in Beijing,an authentication and management system of non-polluted agricultural product,green food,and organic food in Beijing is put forward,combining with specific demands of production-sale service station for good-quality agricultural product in Beijing.Based on WebGIS and spatial-temporal database,the organization,database,functional design,and application of the system are completed.

Agricultural environment is the basis for the survival of agricultural production,whose advantage and disadvantage affects the quality and quantity of agricultural products directly.In this paper,agricultural environment monitoring system is established based on GIS with technologies including Cross positioning,Logical querying,Spatial analysis and Spatial database matching etc.This system realizes the management,quality assessment,alarm in advance and the management and assessment of agricultural products information and quality to agricultural soil environment monitoring stations,and achieves dynamic monitoring to agricultural environment and offer support for managers on macro-decision.The point of this paper is to expatiate the design and implementation of this system.
