【摘要】 本文选择了黑龙江省绿化工作较为突出且具区域代表性的五个城市为研究对象。通过对城市绿化树种的生长状况、观赏特性和生态适应性等进行全面的调查，拍摄近150种2200多张园林树木的图片，录像资料近六小时；对我省城市绿化树种的应用状况进行分析和总结；查阅了大量文献，收集整理出不同树种的相关资料，确定不同城市绿地的树种应用范围，并分别建立了五个城市七大类绿地的园林树种知识库。通过模拟园林专家的思维，研究探索园林树种应用的“产生式”推理规则，应用计算机程序设计，研究开发出“黑龙江省城市绿化树种专家系统”。 该系统由哈尔滨市、牡丹江市、佳木斯市、七台河市和大庆市五个子系统组成，具有代表性、直观性、方便快捷性、经济合理性，以及良好的扩容性和创新性。系统不仅形象直观，而且操作简便，适合各个阶层的园林设计者使用。使用者可按树种的生长类型、主要观赏特性、土壤的酸碱度、光照强度、湿度条件、特殊生态功能和园林用途的需求任意选择，随机组合，可方便快捷地搜索出应用的树种名称、相关特性资料及具观赏性的图片。 随着计算机技术的发展，专家系统已经应用于工业、农业、环境保护以及国防军事等各个领域中。但在园林树种方面专家系统的应用尚未见报导。这个专家系统的建立，将为适地适树、科学地选择树种提供依据；同时可大大提高工作效率，降低成本。对黑龙江省的城市绿化乃至绿地生态系统的建设有重要实际应用价值。本文的研究结果，填补了这项研究的空白，也为探索更为复杂庞大的城市绿化专家系统奠定了重要基础。更多还原

【Abstract】 The test selected five representative cities as the study objects. Those cities are stand out at their virescence work. This paper investigated the living conditions, ornamental characters, ecological adaptability of the trees species in the five cities. It analyzed and summarized the applications of the garden trees, took more than 2200 photos of almost 150 kinds of trees and finished almost 6 hours’ video material. By consulting many documents, collecting and putting in order the relevant information of different kinds of trees, it determined the apply scope of different trees in different cities and Greenland, and built up 7 garden trees repository of the 5 cities. In the repository, by imitating the thought of garden experts, it researches the "produce style" reasoning rule in the use of the garden trees. By using the computer process planning, founds the "urban Garden Trees Expert System of Heilongjiang Province".The system composes of Harbin, Mudanjiang, Jiamusi. Qitaihe and Daqing five subsystems. It’s creative, representative, directly visual, convenient, economical, reasonable and easily extended. System is not only friendly and can be easily operated. It is adapted for the garden designers of every stage. The user can optional choose and randomly combine the trees’ living styles, the main ornamental characters, the soil acid value, the sunlight intensity, the humidity condition, the special ecological function and the needs for the trees. The system can search out the proper trees’ names, relevant character and ornamental pictures conveniently and quickly. With the development of computer technology, the Expert System has been used in many fields such as industry, agriculture, environmental protection and national defense, etc, but the using of an Expert System in garden trees has never be seen reported. This Expert System provides scientific basis for choosing the proper trees scientifically. It can heighten the work efficiency greatly and reduces the costs. It is of momentous significance for the virescence and ecological Greenland System of the cities in Heilongjiang Province. The research results can pad the vacancy in the research. And it will become the basis for the more conplicated and larger urban garden trees expert system.更多还原
