| 摘 要： | 在法瑞学派样地调查法的基础上，采用双向指示种分析（TWINSPAN）和趋势对应分析（DCA）对大山包黑颈鹤自然保护区草甸植被进行数量分类和排序研究。调查样地包含114个物种，分属31科72属，其中禾本科（14种）、菊科（13种）、蓼科（8种）、石竹科（6种）、玄参科（6种）等科所含物种较多。经TWINSPAN分类，106个样地分为20个聚组，根据其指示种确定为20个群丛。样地DCA和物种DCA排序结果反映了植物群丛与指示种之间的一致关系，排序轴的生态学意义说明水分和海拔两个环境因子同时影响该区草甸植被的分布。

| Abstract: | Based on the Braun-Blanquet method of Relev 6 synthesis, TWINSPAN quantitative classification and DCA ordination of meadow vegetation was studied in Dashanbao Black-necked Crane Nature Reserve. Finally, samples contained 114 species which belong to 31 fanlilies and 72 genus. The most abundant families were Poaceae, Asteraceae, Polygonaceae, Caryophyllaceae, and Scrophulariaceae. One hundred and six samples were categorized into 20 groups and divided into 20 associations according to the indicator species. The result of samples and species DCA ordination inflected the consistent relationship between the associations and indicator species. The ecological explanation of ordination axis illustratted that both of the soil moisture and elevation affected the distribution of meadow vegetation in this area. |
