【摘要】 以空间技术、网络技术、数据库技术以及虚拟现实技术的发展为基础的决策支持系统(DSS),与地理信息系统(GIS)和人工智能技术(AI)相结合,正向着高度的交互性以及高度的集成化方向发展,针对其可视化技术的研究也越来也受到广泛的重视。DSS中的可视化技术应用主要包括人机界面的设计与优化、视频编辑、计算机辅助制图以及三维虚拟飞行等方面,其中重点是计算机辅助制图以及三维虚拟飞行。 生态规划工作需要依据科学的自然生态规律,实现人与自然和谐的可持续发展,因此,迫切需要研究生态城市规划决策支持系统(ECPDSS)的可视化技术应用,实现生态规划的定量化设计和管理。可视化技术的应用,可以有效解决可视化手段单一的问题,使决策者和ECPDSS的人机交互程度更加充分,从而提高ECPDSS的决策支持效率;可以直观方便的对现状以及ECPDSS优化方案进行展示,从而提高ECPDSS的易用性和可理解性;可以辅助规划图件的制作,提高规划图件制作的制作精度、制作效率、美观程度和可复用程度;可以面向公众,提供界面友好的信息查询服务,并直观的展示出查询结果,能够有效增进公众参与和互动。 本文结合杭州生态市规划决策支持系统HZECP-DSS的建设工作,从三维虚拟飞行和规划图件辅助制作方面,对可视化技术在以3S技术(主要是地理信息系统技术和遥感技术)为基础的ECPDSS中的应用和集成进行了研究。对采用l:25万杭州市基础地理信息数据(2002年)和杭州市TM卫星遥感影像(1999年),在GIS平台软件Arc/Info 8.1和遥感影像处理软件ERDAS Imagine 8.6环境下进行了杭州市三维虚拟飞行制作的研究和探索,并对基础数据的选择、坐标投影的选择、其他信息的叠加以及中文注释的实现等具体问题进行了探讨。在GIS平台软件Arc/Info 8.1和平面设计软件CorelDraw 11.0环境下,从纸质图件的数字化、规划现状图/定量分析结果图/概念图的制作方面对规划图件辅助制作进行了研究,并对地貌晕渲的制作、透明颜色填充等特殊效果的制作以及符号系统的制作等具体问题进行了探讨。通过对ECPDSS的可视化技术应用的基本方法和集成方式的分析,结合HzECP一DSS的应用需求和设计情况,对HzECP一DSS的可视化技术应用需求进行了分析,提出了HZECP一DSS的可视化技术的应用目标,并从可视化技术应用方面对HZECP一DSS的相关子系统提出了设计要求,得出了可视化技术应用和集成的设计方案。

【Abstract】 Based on the development of spatial technology, networking technology, database technology, and virtual reality (VR), combining with geographic information systems (GIS) and artificial intelligence (AT), the study of decision support systems (DSS) is advancing towards high interactivity and high level of integration. Recently, many attentions had been paid on the research of visual techniques of DSS, especially on computer aided mapping and 3D virtual flights.Ecocity Planning DSS (ECPDSS), integrated with spatial technology, networking technology and distribution technology, is an urgently requirement of China’s ecocity planning projects. The application of visual techniques in ECPDSS could improve the decision supporting efficiency of ECPDSS, improve the display methods and comprehension of current conditions and optimized scenarios, improve the accuracy, efficiency, beauty and reusability of planning maps, and improve the system interactivity with the public.Based on the research of Hangzhou Ecocity Planning DSS (HZECP-DSS), application and integration of visual techniques in 3S based ECPDSS were studied. Supported by Arc/Info 8.1 and CorelDraw 11.0, the research of planning maps automatic generation was studied. The drawing of topographical shading, the usage of special effects as interactive transparency and the design of symbol systems were also discussed. Supported by Arc/Info 8.1 and ERDAS Imagine 8.6, Hangzhou 3D virtual flight show was generated based on 1:250,000 geographic data (2002) and the TM image (1999) of Hangzhou. The choice of data types, coordinate and projections, the overlay of other information and the implementation of Chinese annotation were discussed.Routine methods and application demands of application and integration of visual techniques of ECPDSS were analyzed, and goals of the application were proposed consequently. The design of HZECP-DSS was argued, and therecommended methods of application and integration of visual techniques were proposed.
