佳木斯绿地常见灌木绿色量及叶面积指数的研究

Green Biomass and Leaf Area Index of Common Shrubs in Jiamusi City

该研究对佳木斯绿地常见灌木的绿色量及叶面积指数进行了测定,结果表明,绿色量与6种灌木的冠高、冠幅呈极显著正相关;通过冠幅、冠高、叶面积等参数的测算,拟合出6种灌木的最佳绿色量测算模型;通过拟合出的绿色量回归方程,对相同条件下不同树种的叶面积指数大小进行比较,在6种灌木中,辽东水蜡的叶面积指数最大,黄刺玫的最小。

The study on green biomass and leaf area index of common landscape shrubs in Jiamusi green space showed that the green biomass was positively correlated with the crown height and crown width of 6 shrubs.Throughthe calculation of parameters such as crown width,crown height,and leaf area,the best green amount measurementmodel for six kinds of shrubs was fitted.By fitting the regression equation of green biomass,the leaf area index of dif-ferent tree species under the same conditions was compared.Among the six shrubs,the leaf area index of Ligustrum obtusifolium was the largest,and that of Rosa xanthina was the smallest.
