Study on the Community Characteristics of Quercus mongolica Forest in Baihuashan National Nature Reserve

doi:10.13466/j.cnki.lyzygl.2021.03.013

Abstract

Abstract:

In order to effectively grasp the status quo of plant species diversity in Baihuashan National Nature Reserve,the Quercus mongolica community in Beijing Baihuashan National Nature Reserve was investigated.A total of 12 species of trees,29 species of shrubs and 49 species of herbs were investigated.Data analysis showed that Quercus mongolica was the dominant tree species in the community and dominated in the main forest layer;Rubus crataegifolius was the dominant species in the bush layer.The important dominant species in the herbaceous layer were Carex lanceolata and Deyeuxiaarundinacea.

Key words: Baihuashan, nature reserve, Quercus mongolica, species diversity
