摘要
选取北京市168个公园植物群落进行调查,于2015年夏季测量群落绿量,对群落的垂直结构进行分析,将绿量与群落结构参数进行了相关性分析。结果表明,样本中出现最多的群落垂直结构为乔+灌+草,其数量占样本总数的56%,这些群落的绿量值普遍较大。样本绿量值基本符合正态分布,其分布最多的区间为1.8~2.0。绿量与乔木层平均冠幅、乔木层平均树高、乔木层平均胸径、乔木层盖度、群落总盖度之间存在极显著的相关性。通过计算得出了绿量与群落结构之间的最优回归方程:y=1.297x_1+0.701x_3+1.262(y为群落绿量,x_1为乔木层平均胸径,x_3为乔木层盖度)。
168 plant communities from urban parks in Beijing were selected as samples for this study.This study were conducted in the summer of 2015.The vertical structure of the community was statistically analyzed,and the correlation between the vegetation quantity and community structure parameters was analyzed.The results showed that the vertical structure of the community in the sample was arbor + shrub + grass,accounted for 56%of the total number of samples.The values of the green values of these communities were generally larger.The vegetation quantity was significantly positively correlated with the average crown of tree layer,the average height of tree layer,the average diameter at breast height of tree layer,the coverage of the tree layer,the coverage of the plant communities.The multiple regression equation between the vegetation quantity and the plant community structure was estimated:y = 1.297x_1+0.701x_3+ 1.262(y is the vegetation quantity,x_1 is the average diameter at breast height of tree layer,x_3 is the coverage of the tree layer).
