After having reviewed, analyzed and discussed the history and advances of research on theories and methods of landscape classification between our country and others, based on the basic theories, principles and foundations, The paper combined the current situations and characteristics of the rural landscape of our country, put forward a kind of method of rural landscape classification named the method of functional and configurational classification which served rural landscape planning of small scale.

本文总结了国内外景观分类理论与方法的发展现状，分析了目前景观分类中的优缺点，结合我国乡村景观的现状和特点，运用乡村景观分类的基本理论，依据乡村景观分类的原则和依据，提出了一种基于小尺度的服务于乡村景观规划的乡村景观分类方法，即乡村景观功能形态分类法。

The contents included the followings : Nomenclature of trees , History of dendrology taxonomy , System of classification , Influences and fruit , Terms of taxonomy , Classification of tree farms , Classification of Gymnosperm , Classification of Angiosperm.

其内容如下：树木的命名、树木分类的历史、分类系统、花序及果实、分类的术语、木本蕨类之分类、裸子植物之分类与被子植物之分类。

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。

By Llibre's algebraic invariant theory, at first on the basis of classification for quadric and quadric homogeneous binary polynomial, the plane linear and cubic homogeneous polynomial differential systems are classified.

利用Llibre的代数不变式理论，首先由二元二次和二元四次多项式的分类结果，对一次和三次齐次多项式微分系统进行代数分类，同时补充了已有结果中出现的漏洞；其次，由称共变张量空间的性质，对缺二次项的三次微分系统在保证轨线走向不变的前提下进行代数分类，使分类后同类系统的示性多项式有相同零点；最后通过讨论一类简单系统的有界性说明了分类的方便方处。

With the found of new Rhizobium resources and development of science and technology,Rhizobium taxonomy has transfer from tradition classification to modern systematic taxonomy.

随着根瘤菌资源的不断发现和科学技术的不断发展，根瘤菌分类从以互接种族为依据的传统分类逐步过渡到了以系统发育关系为依据的现代系统分类，特别是近十几年来，生物技术应用于根瘤菌系统发育及其分类的研究进一步促进了根瘤菌资源的开发利用，使得根瘤菌的分类及其系统发育研究有了突破性进展。

A new multiclass SVM algorithm based on binary tree was introduced on E-mail filtering. It could convert multiclass problem to binary classification by constructing binary tree. The idea of clustering first and classification later was adopted, and the largest similarity between testing sample and sub-category center and the separation measure of sub-categories were calculated, in oder to construct the optimal class hyperplane of decision-making nodes.

提出一种基于二叉树的多分类SVM算法用于电子邮件的分类与过滤，通过构建二叉树将多分类转化为二值分类，算法采用先聚类再分类的思想，计算测试样本与子类中心的最大相似度和子类间的分离度，以构造决策节点的最优分类超平面。
