【摘要】 松材线虫病是影响森林健康的主要因素之一。松材线虫病管理信息系统的研建对有效控制松材线虫害危害，保证林木的健康生长，巩固造林绿化成果，促进生态环境建设，充分发挥森林的生态、经济、社会效益有着重要的意义。随着空间信息技术的发展，作为地球空间信息核心技术--“3S”技术也正发展和完善。在松材线虫病管理信息系统中，应用“3S”技术具有广泛的研究前景。该系统建立在松材线虫病信息网络管理平台的基础上，综合运用了“3S”技术、网络技术、虚拟仿真技术，实现了松材线虫病信息的集成化管理。 林业从计划经济向市场经济转轨，信息管理的方式方法和技术手段都发生了变化，松材线虫病管理信息系统以广州市松材线虫病为管理对象，分析了松材线虫病的特点，比较了国内外对松材线虫病管理信息系统研究的发展状况，利用现代科学技术、航空录像技术提供的信息手段，在管理目标约束下，对广州市松材线虫病管理信息系统等问题进行了如下研究。 (1)论述了建立广州市松材线虫病管理信息系统的可行性，指出了建立该系统的理论基础和技术基础，构建了广州市松材线虫病管理信息系统的体系框架。 (2)通过航空录像获得航片信息，GPS技术采集地面信息，实现了实时获得松材线虫病的属性数据和空间数据功能。 (3)经过数据分析，监测松材线虫孳生地的分布以及松材线虫导致的森林损失情况、灾害程度分级，设计最佳的防治计划和最优防治路线。 (4)建立了适合广州市松材线虫病生命系统模型，对广州市松材线虫病发生、传播、迁移、扩散动态过程进行模拟，并建立相应的灾情损失评估模型，比较模型模拟得到的数据与实际调查得到的资料，对模型模拟结果进行评价。 (5)运用GIS的技术优势，根据松材线虫病发生和防治数据、松树资源及监测信息、气象信息等因素进行综合分析，应用灰色系统理论等预测预报模型实现对不同区域、不同时期发生和危害情况的松材线虫病的预测预报。 (6)研制了基于“3S”技术的广州市松材线虫病管理信息系统，构成了整体的、实时的和动态的松材线虫病的发生发展状态的监测、防治、预测预报系统，从而及时、有针对性的实现了松材线病的综合治理。 松材线虫病管理信息系统的集成是一个综合的概念，它需要应用信息技术等多种高新技术。本系统采用ArcGIS8.2作为地理信息平台，采用面向对象的设计方法，以Visual Foxpro 6.0、PowerBuilder 8.0为开发工具。后台采用ORACLE 9数据库，前端采用Windows 2000 Professional操作系统。更多还原

【Abstract】 Bursaphelenchus xylophilus Nickle disease is the one of major factor that affects the health of forest. Bursaphelenchus xylophilus Nickle Disease Management Information System grind build for effective control Bursaphelenchus xylophilus Nickle disease harmful harm, guarantee the healthy growth of woods , strengthen afforestation forestation accomplishment , promote the construction of ecological environment, develop economy and the ecology of forest fully , social benifit have important meaning. Along with the development of the technology of spatial information, as the key technology of the earth of spatial information -3S technical also straight development with perfect. In Bursaphelenchus xylophilus Nickle Disease Management Information System, apply the technology of 3S to have extensive research prospect. This system has synthesized on establishment Bursaphelenchus xylophilus Nickle disease foundation of ill information network management platform the integrated management that has realized Bursaphelenchus xylophilus Nickle disease information with 3S technology, network technology and fictitious emulation technology.Forestry turns rail, the ways and means of information management and technical means from planned economy to market economy, have occured change , Bursaphelenchus xylophilus Nickle Disease Management Information System is taking Guangzhou city Bursaphelenchus xylophilus Nickle disease as management, have analysed the characteristic of Bursaphelenchus xylophilus Nickle disease for elephant, have compared domestic and international for the Bursaphelenchus xylophilus Nickle disease research of management information system development condition, record using modern science and technology and aviation as technology offers , information means, under management goal restraint, for Guangzhou city Bursaphelenchus xylophilus Nickle disease, the problems such as management information system are as follows to study.(1) Have discussed establishment the Guangzhou city feasibility of Bursaphelenchus xylophilus Nickle Disease Management Information System, have pointed out establishment the theoretical basic and technical foundation of this system, have founded the system frame that Guangzhou city Bursaphelenchus xylophilus Nickle Disease Management Information System.(2)Through aerial record, picture gets navigation flat information and GPS technicalcollection ground information , really gets space data function and the property data of Bursaphelenchus xylophilus Nickle disease when realizing.(3) Via data analysis, inspection Bursaphelenchus xylophilus Nickle breeds the distribution of land as well as the forest loss condition that Bursaphelenchus xylophilus Nickle causes and calamity level to grade , designs the planned and optimum route of the best of prevention and cure of prevention and cure.(4) Have established to suit Guangzhou city Bursaphelenchus xylophilus Nickle disease life systematic model, for Guangzhou city Bursaphelenchus xylophilus Nickle disease, disease is occured and propagated , move and proliferation development course imitate , and establish the corresponding loss assessment model of the condition of a disaster , compare the model information and that data and actual investigation get that can be imitated , appraise for model simulated result.(5) With the technical advantage of CIS, according to Bursaphelenchus xylophilus Nickle disease occur with the data of prevention and cure, the resource of pine tree and inspection information , meteorology the factors such as information carry out integration analysis, the forecast forecast models such as application grey systematic theory realize , is for different area , not same time the forecast forecast that occurs the disease of the Bursaphelenchus xylophilus Nickle disease of and harm condition.(6) The Guangzhou city Bursaphelenchus xylophilus Nickle Disease Management Information System that has developed the technology based on 3S has formed overall, real time and dynamic Bursaphelenchus xylophilus Nickle disease, is ill to更多还原
