| 摘要: |
| 对江西省三清山钩锥—山蜡梅群落进行了调查和分析。结果表明:(1)群落共有种子植物40科56属81种; 其中热带属占63.04%,温带成分占36.96%。(2)群落多样性指数D=0.85,H'=2.77,PIE=0.85,Jsw=0.68,Jsi=0.86,Ea=0.37。(3)群落优势科组成主要为壳斗科、蜡梅科、樟科,而以钩锥和山蜡梅占绝对优势。(4)生活型以高位芽植物占绝对优势,地上芽植物,地面芽植物和隐芽植物都较少,无一年生植物。(5)群落组成以双优势种为特征,六个优势种群的年龄结构图均为衰退种群。其频度规律为A>B>C>D<E,同Raunkiaer标准频度定律近似。(6)总体看来,该钩锥—山蜡梅群落是一个典型的亚热带地带性常绿阔叶林,并具有较丰富的热带成分。 |

| Abstract: |
| According to a filed survey and analysis of plot data,the characteristics of plant community of Castanopsis tibetana -Chimonanthus nitens in Sanqing Mountain in Jingxi province,China was studied.The results showed that:(1)There are 81 species spermatophyte form 56 genera belonging to 40 families,which the tropical genera is occupted 63.04%,and the temperate genera is occupted 36.96%.(2)In the community D=0.85,H'=2.77,PIE=0.85,Jsw=0.68,Jsi=0.86,Ea=0.37.(3)The community dominant families is mainly the Fagaceae,Calycanthaceae,Lauraceae,Castanopsis tibetana and Chimonanthus nitens are absolutely dominant.(4)The analysis of the life forum show that the phanerophytes are preponderant.There also have some chamaephytes,hemicryptophytes and cryptophytes,but have not annual plants.(5)The community composes is characteried by two-dominant species.The age forum show that the six dominant populations are declining.The frequency grades is A>B>C>D<E,which is similar to Ranukiaer's law of frequency.(6)As a whole,this community is a subtypical evergreen broad-leaved forest,which has abundant tropical elements. |
