摘 要:利用可拓共存度分析法与线性约束分析法,探讨天然异龄林评估资产核查起测直径提高的理论可能性。结果表明:只要能保证平均每厘米起测直径升幅的蓄积量平均误差足够小,就存在提高起测直径的可能;并以丰富的样地数据资料证实了天然异龄林因其直径分布结构特点而具有提高起测直径的现实可能。In this paper the theoretical possibility of raising the minimum measured diameter among assets verification for natural uneven-aged forest was discussed through extension coexist degrees and linear con-straints method.The result showed that there was the possibility of raising the minimum measured diameter un-der this condition that average error of stock volume was sufficiently ensured as small as possible.And the real-ity of raising the minimum measured diameter for natural uneven-aged forest was confirmed,because of its di-ameter distribution characteristics,by using rich plot data.
