| 摘 要： | 为探求小面积人工绿地三维绿量的分布特征及快速有效的测算方法，以杭州市3家疗养院绿地为研究对象，从中筛选36个20 m 20 m的样地，通过调查并对数据进行处理得到14个群落指标。依据林木的分形原理，采用对群落指标进行Pearson相关显著性检验和逐步回归的方法，获得4个模拟方程。结果表明:样地总体三维绿量呈正态分布，其中乔木层三维绿量占总三维绿量的近90%。4个模拟方程决定系数R2为0.922~0.973，残差分析没有呈现明显图案，所得最优方程为y=2 679.155x11+77.620（y为模拟三维绿量，x11为胸高断面积）。根据模拟方程标准回归系数，14个因子中对小面积人工绿地三维绿量影响最大的因子为胸高断面积。图2表7参22

| Abstract: | This study was conducted to find a method for measurement and distribution of three-dimensional green biomass （TGB） in an artificial greenbelt of a small area. Thirty-six 20 m 20 m plots from artificial greenbelts of three sanatoriums in Hangzhou were chosen, and destructive measurements were used. According to a field vegetation survey，14 community indicators were selected, and then a stepwise regression and a Pearson correlation test were carried out to derive a total of 4 simulated equations for TGB. Results showed that overall，TGB had a normal distribution，and the tree layer took up nearly 90% of the total TGB. The coefficient of determination （R2） for the 4 simulated equations ranged from 0.922 to 0.973，but no evident pattern was shown in the residual analysis meaning that the simulated equations could be used to predict TGB of the artificial greenbelt. The most convenient simulated equation was y = 2 679.155x11 + 77.620，where y was simulated TGB and x11 was basal area at breast height. Thus，according to the standard regression coefficients for the simulated equations，basal area at breast height was the most important factor affecting TGB of a small area，artificial greenbelt. ［Ch，2 fig. 7 tab. 22 ref.］ |
