摘要
根据福建省火炬松人工林林分优势木的树干解析数据 ,以 Richards函数为数学模型 ,用改进单纯形法拟合优势高生长曲线 ,推导出适合福建省火炬松人工林的多形地位指数曲线综合模型 .
Taking Loblolly Pine plantations as examples and according to the sample plot and steam analysis materials collected in Fujian Province, this paper selects adjusted Richards functions as tree growth curve models to derive the multiple form site index curve comprehensive models suitable for Loblolly Pine in Fujian Province, simulating the height growth curve of dominant tree by the improved pure form comprehensive models As a result, this multiple form site index curve comprehensive models are available in forestry production
