东北红豆杉连年生长量初步分析
|
摘要
在东北红豆杉主要分布区选择有代表性的林分,确定树龄相近的单株(30～40 a)调查连年生长量,分析不同林分间连年生长量的变异规律及生长与气候因子的相关性.结果表明:不同林分间连年生长量差异显著,变异系数为43.6%,呈现出随着纬度升高生长量降低的变异规律;同一林分内个体间变异系数为23.5%～44.7%;主枝长度生长量与积温、无霜期和降雨呈正相关,相关系数分别为0.728 5*,0.717 9*,0.639 8;侧枝长度与积温和降雨的相关性很弱,与无霜期呈不显著负相关;针叶长度与积温、无霜期、降雨呈不显著负相关;针叶宽度与积温、无霜期、降雨呈正相关;枝条伸长生长与针叶长度、宽度和叶面积呈极显著正相关.
In the main distribution area of Taxus cuspidata,a representative stand was selected to determine the single tree( 30 ～ 40 a) of the tree age,and annual growth was investigated. Annual growth variation of different stands and correlation between growth and climatic factors were analyzed.The difference of annual growth between different stands was significant.The coefficient of variation among the stands was 43.6%.The higher the latitude,the lower the growth.The coefficient of variation between individuals in the same stand ranged from 23.5%to 44.7%.There was positively correlated among the growth of main branch length of Taxus cuspidata and accumulated temperature,frost-free period and rainfall,and the correlation coefficients were 0.728 5*,0.717 9*and 0.639 8,respectively.The correlation among lateral branch length and accumulated temperature and rainfall is weak.There was no significant negative correlation with frost-free period. Needle length and temperature,frost free period,rainfall was not a significant negative correlation. There was no significant negative correlation among needle length and accumulated temperature,frost-free period,rainfall. It was positively correlation among needle width and accumulated temperature,frost-free period,rainfall. It was extremely significant positive correlation among branches straight growth and needles length,width and leaf area.
