Abstract:

 Based on the BraunBlanquet method of Relev é 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 families 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.
