| Abstract: | The survival rate, mean age and expectation of both non-timber forest and other forests (all kinds of forests except the non-timber forest) are calculated based on the data of the two recent measures of the Continuous Forest Inventory System of 16 provinces. The comparison shows that the non-timber forest is much unstable than other forests. |
