研究了齐齐哈尔市龙沙公园乔木、灌木树木群落的组成、分布和结构特征。通过对20个样方727株树种调查,结果表明,龙沙公园内共有树木11科18属25种。乔木胸径大多集中在8～24 cm,约占调查乔木总量的80%;冠幅小于0.5 m的占40%以上,其他冠幅分布比较均匀;各树种重要值比较均衡,由于气候、地域原因和人为干扰,种群丰富度较低。

The composition,distribution structural characteristics of communities of trees shrubs in Longsha park of Qiqihar City were studied.Through investigations on 727 species in 20 quadrats,result shows that： Longsha Park have a total of 11 families,18 genera 25 species of trees.DBH of tall trees are mostly concentrated in 8-24 cm,constituting 80% of the total trees;crown（less than 0.5 m） account for more than 40%;other crowns are more evenly distributed;the important value of each species is more balanced;as a result of climate,geography causes human disturbance,species richness is low.
