| Abstract: | Based on the analysis of the diameter measurements of sample trees in Continuous Forest Inventory (CFI), it was pointed out that the large diameter class survivors with lower growth and higher measurement errors might cause the estimate of growth to be positively biased, and some examples were given for verification Finally, some suggestions were presented to avoid bias |
