经验收获表及其在用材林资产评估中的应用

The experience yield table and its application in property evaluation for timber forest

采用 Schumacher方程描述平均胸径和平均树高的生长过程 ,并用平均胸径和平均树高建立株数预估模型 ,在此基础上 ,结合林分收获模型及有关公式编制了杉木人工林经验收获表 ,该表经检验证明适用 .

Base on combining the stand yield model with related equations,the experience yield table for Chinese fir plantation has been established by describing the growth process of average diameter and average height with Scbumacher equation as well as by making the individuals predicting model with average diameter and average height The table has been proved to be practical by test,then its application in predicting growth yield and evaluating forest property were probed further more
