摘要
本文以杉木、马尾松人工林为例,根据在福建省南平、三明等地区收集的标准地和树干解析资料,选用Richards函数为树木生长曲线模型,推导出适合南方杉木、马尾松人工林的多形地位指数曲线综合模型,并对单形和多形地位指数曲线进行了对比研究,结果表明多形地位指数曲线的拟合精度明显高于单形地位指数曲线。
Taking Cunninghamia lanceolata and Pinus massoniana plantations as examples and according tothe sample plot and stem analysis materials collected in the prefectures of Nanping,sanming,etc. in FujianProvince,this paper selected Richards functions as tree growth curve models to derive the multiple-form siteindex curve comprehensive models suitable for C. lanceolata and P. massoniana plantations in Fujian Province,
