Abstract

In continuous forest inventory (CFI), according to normal calculating method of unmeasured cut , it is considered that the unmeasured cut is affected by different psecies of tress and classes cut , but which ignored that the beginning foest stock of cut distrbutes with gradient on per-year and does unevenly before and after the growing season in a certain year .As a result of study , authors thought that the four factors should be considered together , then guided corresponding calcuating formula .From the result of examples , we can see the calculated unmeasured cut in different conditions is higher between 9.9 % to 37.4 % than it in the condition based on the four factors .
- forest resources,
- continuous forest inventory,
- forest stock,
- unmeasured cut
