摘要:对鸡公山、大岗山和洪雅种源试验的调查材料,用随机效应检查和固定效应检查两种方法检验和比较了同一地区不同种源对断面积生长模型的影响。结果表明,种源试验中采用随机效应检查较好,固定效应检查容易造成差异显著的误判。随机效应检查的结果表明,同一地区不同种源的断面积模型相同。
Two methods for testing the impact of Chinese fir provenances planted on the same region on their basal area growth models,random effects test and fixed effects test,were compared with the data from three forest farms,Jigongshan,Dagangshan and Hongya.The result showed that random effects test was better while fixed effects test tended to refuse wrong the null hypothesis of no significant difference in parameters of basal area models among Chinese fir provenances.Meanwhile,the result showed by random effects test demonstrated that basal area models of provenances planted on the same region was of no significant difference.
