摘 要:
【Objective】To clarify the species composition and flora characteristics of rare and endangered protected seed plants in the Daqingshan National Nature Reserve,and provide references for the effective protection and rational development and utilization of seed plant resources in the reserve. 【Methods】Based on field survey data and literature,a list of rare and endangered protected seed plants in the Daqingshan National Nature Reserve was formed. And the floristic research method was used to study the flora geographical components. 【Results】There were 53 species of rare and endangered protected seed plants in the Daqingshan National Nature Reserve,belonging to 24 families and 38 genera. Among them,there were 12 species of national secondary key protected wild plants,22 species of Inner Mongolia rare and endangered protected plants,and 29 species of Inner Mongolia rare forest trees. The life form of seed plants was mainly woody plants,with a total of 29 species,accounting for 54.7% of the total number of rare and endangered protected seed plants in the Daqingshan National Nature Reserve;23 species of herbaceous plants,accounting for 43.4% of the total. The water ecotype was dominated by mesophyte,with 43 species,accounting for 81.1% of the total. The flora was dominated by North China and East Asian distribution species. 【Conclusion】The flora of the Daqingshan National Nature Reserve was rich in geographical elements and had obvious temperate properties,reflecting the flora characteristics of Daqingshan.
