昆明昙华寺公园园林植物群落结构分析

Structural Analysis on Landscaping Plant Communities of Tanhuasi Temp Garden.

采用典型抽样的方法对昆明昙华寺公园中的前园与中园、后园的园林植物群落进行物种结构、水平结构、垂直结构和季相的调查与分析。前园共有植物73种，分属于40科、63属。中园共有植物73种，分属于38科、53属。前园树种丰富度为6．32。树种多样性指数为3．45。中园树种丰富度为5．56，树种多样性指数为3．39。后园树种丰富度为5．94，树种多样性指数为3．34。中园胸径超过3cm。冠幅超过9m所占总数的百分比远比其它园区多的多。前园与中园乔木树高主要集中在10．7m以上，后园树高在4．6～10．7m的最多。3个园区的园林植物群落季相变化都不是很明显。

The species structure,lateral and vertical structures and the seasonal aspects were investigated and analyzed on landscaping plant communities in New Garden and Old Garden of Tanhuasi Temp Garden. There were 73 plant species belonging to 40 genera and 63 families in Forward Garden. There were 73 plant species belonging to 38 genera and 53 families in Middle Garden and 77 plant species belonging to 33 genera and 47 families in the Back Garden. The trees richness is 6.32 and the trees diversity indices is 3.45 in Forward Garden. The trees richness is 5.56 and the trees diversity indices is 3.39 in Middle Garden. The trees richness is 5.94 and the trees diversity indices is 3.34 in Back Garden. The diameter at breast height of trees percent and the diameter at coronal of trees percent are far more than other gardens. The height of trees concentrates over 10.7m in Forward Garden and Middle Garden. The height of trees concentrates at 4.6m～ 10.7m in Back Garden. Seasonal changes of landscape plant community are not obvious in both gardens.
