摘要
利用广西大青山单叶省藤和黄藤人工林多年固定样地调查和采收资料,选择Richards、Korf、Logistic、Gompertz和Mitscherlich等5种理论生长方程,分别建立藤林母茎长、萌茎长和萌蘖数与年龄的相关关系,并对拟合效果进行对比分析。结果表明:除Mitscherlich方程拟合单叶省藤萌茎长时相关指数小于0.90外,其它方程拟合的相关指数均高于0.92;Korf和Rich-ards方程的拟合最高,Gompertz方程次之,而Logistic和Mitscherlich方程的拟合效果最差;与Richards方程相比,Korf方程更能准确描述单叶省藤和黄藤林分的生长特性,更适合于建立单叶省藤和黄藤人工林的生长模型。
Based on the data collected from permanent plots and harvest trials in Calamus simplicifolius and Daemonorops margaritae plantations in Daqingshan, Guangxi Province, five growth equations were utilized to establish the correlation between age and growth factors including the length of mother stem, the length of sucker stem and the number of sucker shoot. The fitting effect of these equations was compared. It was found that ha of growth model established with each equation was more than 0. 92 except that of fit- ting the number of sucker shoot of C. simplicifolius and age with Mitscherlich equation, which was less than 0. 90; Korf and Rich- ards equations fitted the correlation between growth factor and age best, followed by Gompertz equation while Logistic and Mitscherli- ch eqations performed worst; Korf equation was more suitably used to describe the growth characteristic of two types of plantations than Richards equation, indicating its greater applicability to establishing growth models for C. simplicifolius and D. margaritae plantations.
