优势种植被分类系统的逻辑分析与示例方案化

A logistic analysis on vegetation classification system based on dominant species with an illustrational scheme

逻辑学原理是各种分类系统科学性及规范性的必要检验工具。本文采用逻辑学原理检验基于优势种的《中国植被》的植被分类系统,结果发现目前常用的植被分类系统存在较多逻辑错误,需要予以纠正。于是,在强调植物生活型分类系统和植被分类系统一致性的基础上,依据逻辑学原理给出建立植被分类系统的步骤和方法,提出规范的植物生活型分类系统和植被分类系统示例方案。鉴于多建群种植被的客观存在及其存在形式多样,在分类系统中给出相应的位置——多建群种植被纲。同时,针对国内植被分类学界从未形成统一的植被命名规则,且又有多种命名方式并存的现状,提出了函数命名法。

This paper aims to introduce a method to test vegetation classification systems based on the dominant species, in order to evaluate the accuracy of the classification system. If the test shows that there are errors in commonly used vegetation classification system, corrections are needed. To correct the existing clas-sification system error, we must build a new system of classification. This paper presents a new vegetation classification system based on dominant species, and identifies the processes and methods to establish the classification system. Logic testing tools are the basis of examining the correctness of vegetation classifica- tion system. In this paper, we confirm that the principles of logic can be used for testing classification sys- tems. Steps and methods to establish the vegetation classification systems are given and the new plant life-form and vegetation classification system are established. We suggest the concept of multi-constructive species vegetation, set, the classified status and present a clear vegetation nomenclature.
