摘　　要：建立了实生杉木村间伐模型：ｃｗ＝１．５０６０＋１７２．５６７６ｏ１．３一０．００９３Ｈ１＋０．０５３９Ａ。该模型可利用全国杉木地位指数表按地位指数制定间伐密度指标，并可用以预估间伐期及间伐量。此外，本模型还可用角规测算胸高面积，以确定间伐密度指标，简化操作程序。Based on investigation ,analysis and compute,a thinning model of Cunninghamia lanceolataplatation was given in this paper:CW=1.5060+172.6576G1.3 0.0093H+0.0539A.According to nationwide cunnighamia lanceolata site index table and each site index,this model canbe used to define thinning density indicator and to eatimate the period and stock of thinning.Moreover,thinning density index can also be detemined by using angle gague to measure andcaJculate the total of basal-area ,which can simplify opration processes.
