滇川干热河谷植被布朗布朗喀群落分类单位的植物群落学分类

The Phytosociological Classification of Braun Blangute'sSyntaxa for the Dry-Hot Valley Vegetationin Yunnan-Sichuan Region

按布朗布朗喀群落分类单位，即从群丛、群属、群目至群纲，用植物群落学的或植物区系－群落学的分类方法，建立了滇川干热河谷植被群纲－群目－群属－群丛分类系统表。表上有元江、怒江和金沙江三江河谷型半萨王纳植被的１个群纲、４个群目、１０个群属和６４个群丛，均由５２３个样地记录归类而成。本系统表是一个简略形式的表，它分别来自三江的３张群纲级的群落分类综合表。本系统表反映滇川干热河谷植被的每个群落分类单位及其植物种类组成的多样性特征和独特结构。

Based on Braun-Blanquet's syntaxa of phytosociological or floristic-sociological classification methods, the classification system table of Class-Order-Alliance-Association of the dry-hot valley vegetation in Yunnan-Sichuan region has been established. In this system table,there are 1 Class, 4 Orders, 10 Alliances and 64 Assciations in the semi-savanna vegetation of valley type of 3 Rivers (Yuanjiang, Nujiang, Jinshajiang), sorted out from 523 releves. This system table is a simple form, it is made from 3 synoptic-syntaxon table (Class table) each for 3 Rivers. The system table reflects the diversity, characeristics and unique structure of every syntaxa and their floristic component, especially character species of the dry-hot vegetation in Yunnan-Sichuan region.
