| 摘 要： | 在北京山区的13个自然保护区针对防护林优势群落进行植被调查,确认有维管植物86科261属454种(含栽培种),外来种有2科4属4种,野生维管植物有85科257属450种。野生维管植物以世界广布科最多,温带性质明显,中国特有属最少。野生植物的生活型以高位芽植物占优势,占总种数的48.45%,地面芽植物种占野生植物种的30.67%,一年生草本植物、地下芽植物和地上芽植物数量较少,分别占野生植物种的12.00%、6.00%和2.89%。基于北京山区防护林优势群落的植物区系分析可为今后北京市生物多样性保护和天然林经营提供科学依据。

| Abstract: | The dominant community of protection forests in 13 nature reserves in Beijing mountainous area included 454 fascicular plant species (including planting species), belonging to 86 families and 261 genera. In addition, there were 4 exotic species belonging to 2 families and 4 genera and 450 wild fascicular species belonging to 85 families and 257 genera. The families of wild fascicular plants distributed in world were the most. The temperate characteristics of the plant genera were very distinct. Not only the genera endemic to china were the least, but also the endemic characteristics of plant were not showed. The life form of wild plants in Beijing mountainous area was dominated by phanerophytes which account for 48.45% of total species. While hemi-cryptophytes were 30.67% of wild species. The first year-herbaceous plants, geophytes and chamaephytes were relative little and were 12.00%, 6.00% and 2.89% respectively. The research maybe could used for guiding biodiversity protection and management of natural forest. |
