【摘要】 在信息技术高速发展的今天,我们认识到现代林业的发展需要计算机技术的支持,网络技术在现代园林事业中也同样扮演着重要的角色。园林树木体系庞大,树木种类繁多,如果要详细的了解树木信息,将树木得到合理的运用,对普通用户来说是具有一定难度的。在我国,对园林树木专家系统的研究起步较晚,该领域的专业技术人员也相对匮乏,相关的信息、资料普及度不够。基于Web的专家系统作为一种程序系统,它是借助于网络平台利用相关的专家知识和经验来解决现实中遇到的问题。利用现有技术建立的专家系统可以对相关园林知识进行查询,可以对相关病虫害进行简单推理,在很大程度上弥补了传统技术的不足。在网络平台运行下,使用者可以使用互联网随时随地使用该系统,用户使用起来更加便捷,大大提高了系统的使用率。通过多次与园林专家进行交流,进行实地调研、查阅大量相关文献等方法获得丰富的园林知识,将相关知识进行分析、归类,整理成为系统所需要的具有一定专家水平的信息,并将这些知识运用到该系统中。本文收录了大量的园林树木和相关病虫害信息,与之相对应的图片多达几百张。该系统在Windows 2003系统下,采用MySql数据库,结合Photoshop等图像处理工具,建立具有浏览、查询、知识库维护功能的系统,该专家系统主要由用户界面、包含园林信息的数据库、推理规则和知识库维护四部分组成。主要研究成果如下:(1)经过知识汇集与梳理,系统中共收录昌邑市常用园林树木种类162种,与之相对应的病虫害也多达几十种。(2)该系统对相关树木的基本属性、形态特征、生态习性、生长类型等进行合理组织,用户可以方便的对昌邑市常见园林树种进行查询。(3)系统采用正向推理与反向推理相结合的策略,根据用户掌握的一个或者几个相关特性,通过推理机作用,快速对相关树木的病虫害进行诊断。(4)用户可以根据实际需要,随时对知识库进行修改、扩充,不断增强系统的整体特性,满足用户的实际需要。更多还原

【Abstract】 As information technology is developing fast, we realize that the development of modern forestry needs the support of computer technology, and the Internet technology plays an important role in the modern forestry. In China, the research of garden specialist system started quite late. We have been lack of relative information, data and professional technicians.As a program system, the specialist system, based on the Web, makes full use of knowledge and experience of relative professors to solve the problems in the reality. At present, the research of the internet-based professor system is still on initial stage. Being built up on the existing technology, the professor system could offset the shortages of traditional technologies by inquiring garden knowledge and simply inferring plant diseases and insect pests. Through the network platform, users can apply the system anywhere anytime by the Internet conveniently, increasing the system’s utilization.All the systematic knowledge of gardening is collected and generalized before being installed in the expert system by communicating with gardening experts, investigating on the spot, referring to lots of professional books.The paper includes a large number of information about ornamental trees and shrubs, and information about plant diseases and insect pests with hundreds photos.Operated under Windows 2003, the system uses My Sql database and the image processing software like Photoshop. The functions of the system include browsing, inquiring, and maintaining the knowledge base. The system consists of 4 modules, namely, User Interface,database, Inference Rules and Knowledge Base Maintenance. The main research achievements are:1. After collecting and sorting out knowledge, the system includes 54 families, 162 species common ornamental trees and shrubs. Up to hundreds of corresponding plants diseases and insects pests.2. The system organizes rationally all knowledge and information on aspects of trees, including their basic attributes, morphological characteristics, ecological habits, growth type, and ecological habits. The user can inquire the common garden trees in Chang Yi conveniently.3. The system utilizes the strategy of forward reasoning. According to one or a few ofrelative symptoms, users can diagnose plant diseases and insects pests for the trees quickly.4. According to users’ actual needs, the knowledge base can be modified and expanded to strengthen the entire characters continually and to satisfy the need of users.更多还原
