摘要：当小班调查得到各组成树种的平均高、平均直径以及小班的年龄、每公顷株数、郁闭度、散生木蓄积等因子后 ,应用天然林分生长模型可以实现无人为干预小班数据的全面更新和连续预测。这些模型应用于小班数据更新时的特点是分别组成树种 ,以地位级指数评价立地质量 ,以预估间隔期代替年龄 ,更适用于天然混交异龄林小班数据的更新。通过吉林省汪清林业局 1 0 8块复位样地的验证 。
Given the stand factors of subcompartment, such as mean height and mean diameter of various tree species composed stand, age, number of stems per hectare, crown density, volume of open grown tree, the forest resource data of subcompartment without human disturbance could be updated completely and predicted continually by using natural stand growth models. These models were of taking composing tree species as updating basis, with site class index representing site quality of a subcompartment, with prediction interval substituting age, and more suitable for updating the data in the natural mixed\|species and uneven\|aged subcompartment. Based on 108 permanent plots from Wangqing Forest Bureau in Jilin Province, the test results showed that the predictions by using the natural stand growth models were better than those by using growth rate in production units at present.
