摘要
利用山东植物群落清查数据,选取山东常见树种为研究对象,分析其树高、胸径特征,采用单因素方差分析法比较树高、胸径在不同海拔区域是否存在显著差异,采用标准化主轴估计法研究不同海拔区域不同树种树高和胸径异速生长关系.研究发现,不同海拔区域间树木的树高、胸径及其生长关系存在显著差异,不同海拔区域各树种采取的异速生长模式有所差异.麻栎、刺槐、栓皮栎这 3 种阔叶树种在不同海拔区域树高-胸径生长关系均呈现异速生长模式,胸径的生长速率大于树高的生长速率.侧柏在低海拔区域胸径的生长速率大于树高的生长速率,而在中海拔区域树高的生长速率大于胸径的生长速率.油松在低海拔区域树高的生长速率较快,而在中海拔和高海拔区域胸径的生长速率较快.赤松和日本落叶松分别在高海拔和中海拔区域采取等速生长模式,在其他海拔区域采取异速生长模式,胸径的生长速率大于树高的生长速率.海拔带来的环境变化能够影响树木的生长过程,但不同树种生长的响应差异是其所处生境和物种遗传特性共同作用的结果.
Abstract
Based on the data of plant community inventory in Shandong Province,the common tree species were selected as the research objects to analyze the characteristics of diameter at breast height(DBH)and tree height.Single factor analysis of variance was used to compare whether DBH and tree height were significantly different at different altitudes.The allometric growth relationship between tree height and DBH of different tree species at different altitudes was studied by standardized major axis estimation.The study found that there were significant differences in DBH,tree height and their growth relationship at different altitudes,and height-DBH allometry of different tree species at different altitudes was different.The height-DBH growth relationship of three broad-leaved tree species,Quercus acutissima,Robinia pseudoacacia and Quercus variabilis,shows allometry growth at different altitudes,and the growth rate of DBH is greater than that of tree height.At low altitude,the growth rate of DBH of Platycladus orientalis was higher than that of tree height,while at middle altitude,the growth rate of tree height was higher than that of DBH.For Pinus tabulaeformis,the growth rate of tree hight is faster at low altitude areas,while the growth rate of DBH is faster in middle and high altitude areas.Pinus densiflora and Larix kaempferi have adopted isokinetic growth patterns in high and medium altitude areas.The environmental changes caused by altitude gradients can affect the growth process of trees,but the differences in growth response of different tree species are the result of the combined effects of habitat and genetic characteristics.
