With the analysis of the features of tree system,potential aspects which could influence tree classification results are studied,the factors that should be taken into consideration in modelling hibernal tree classification are proposed and are concluded to six main aspects of features,amongst them the most correlated contents and information for classification are picked up to set up hibernal trees classification model,and finally implements the classification model with Bayes,which accomplishes a hibernal tree classification system based on Bayes.

通过分析树木体系的特征，研究并分析了可能影响树木分类结果的几个方面，提出了树木分类建模时应该考虑的因素，并将其归纳为六个方面，从中抽取与分类最相关的内容和信息，构建了冬态树木分类的模型，最后用贝叶斯方法实现了该分类模型，完成了基于贝叶斯的冬态树木分类系统。

The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.

为建立植群亚模型，首先依「整合大量样区资料，由下而上的低阶植相聚类」之途径，设计建档程序及转档程式，成功整并不同来源之585个样区资料，但因样区数目不足且分布不均，分析结果未能显示出台湾完整的植群类型；故转循「预先设定植群类型，由上而下的高阶形相分类」之途径，经参考他国植群分类系统及台湾、东亚植群分类研究报告，订定分类原则及架构，提出4阶层之潜在植群形相分类方案：(1)寒原、森林2类群系纲；(2)亚寒带、冷温带、凉温带、暖温带、亚热带5类群系亚纲；(3) 8类群系组表徵优势植群之叶片的物候与形态；(4) 16类群系说明其水分境制及优势分类群；此方案统一处理了过去各种有关植群划分之纷岐名制，方案之各阶植群类型亦即本研究之植群亚模型。

The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study

城乡交错带地区的景观分类，在对城市地区和农村地区的土地利用类型研究的基础上建立了城乡交错带的分类体系，并在此基础上用ARC＼INFO软件分时段、分区、分要素建立研究区的景观图形数据库，对数据进行存储、修改和管理；2）利用多种景观结构、格局指数和斑块面积谱分析方法，从不同的侧面对各种景观组分的结构以及区域的景观格局特征进行了分析，并对其成因进行了探讨；3）利用相同的分析方法，分析了城乡交错带中的城市干道两侧的景观格局特征的空间和时间分异情况，初步掌握上海城市西南轴向扩张的基本过程和规律；4）对城乡交错带中非独立的景观要素-植被，研究其遥感图象信息的基本特征，建立适合区域特点的植被分类体系，并在样区中建立了植被图形数据库和计算机制图，分析了植被景观种类组成、斑块等级等特征以及与不同景观的相互关系；5）在上述研究的基础上，对研究区内的景观生态对策进行了研究。

Borges imagined the possibility of an animal classification system that was vastly different from our common classification system – that of kingdom, phylum, genus and species, or that of wild, domestic, hydrophytic and terricolous – to imply that the set representation system was just one among infinite possible systems, or to imply the existence of another episteme.

博尔赫斯想像着一种与我们常用的动物分类法——比如动物学的类、科、纲、目，或者野生的/家养的、水生的/陆生的——远远不同的另一种分类的可能，暗示着既定的表征系统只是无数可能的表征方式中的一种而已，或者另一种知识型的存在。
