摘要
地位指数曲线模型应是林分优势高生长规律的客观反映。本研究根据大量的样地资料和树干解析数据,探讨了7种方法建模,并对个别模型作了必要的修正。最后,通过检验分析,确定了本研究区马尾松和杉木适宜的地位指数曲线模型为:马尾松:H=S(1-e^(-0.062364.A)/0.846018)~1.476699杉木:H=1.47804·S^0.95496(1-K^(A/20))1.9297.S^(-0.07974) K=1-(S/1.47804·S^0.95496)1/1.97297.S^(-0.07974)并运用模型分别编制了马尾松和杉木地位指数表,供生产部门参考使用。
The site index curve models ought to objectively reflect the height growth process of stand's dominant trees. This study, based on a number of plots and stem analysisdatum, explored seven mothods for founding suitable models,and improved individual modelsappropriately. Ultimately, by test and analysis, the flexible site index curve models of thestudy area were determined:Pinus massoniana: H = S ((1-e^(-0.062364.A))/(0.846018))^(1.476699)Cunninghamia lanceolata: H = 1. 47804 .S^(0.95490)(1 - K^(A /20) )1. 97297.S ^(0.07974) K = 1 - (S/1. 47804 .S^(0.95496))~1/1.97297.S^(-0.07974)And by the two models the site index tables of Pinus massoniana and Cunninghamia lanceolatawere drawn up respectively, giving reference and employment to production departments.
