摘要
对长春市广场树木生长状况和园林植物多样性之间的关系研究表明:广场树木生长状况的数量化值与用Shannon-Wiener指数表示的园林植物多样性之间有良好的相关关系,相关方程为:G=1.972 2+2.667 86Ht-0.644 7Ht2,相关系数R=0.908 57,估计可靠性P=99.9%。
The biodiversity is very important to an ecosystem. In order to know the correlation of growth condition of landscape trees and diversity of landscape plants, we investigated the growth condition of the landscape plants in squares in Changchun city. The results showed that the correlation of the growth condition of the landscape trees and the diversity of landscape plants is very good. The correlative equation is G=1.9722 ＋ 2.66786Ht -0.6447Ht^2 , the R and P are separately 0.90857 and 99.9%.
