Abstract:

The research was based on the data of the last six forest inventories Shandong Province conducted between 1992 and 2017.With the analysis of the changes of land use,tree species and age in the poplar sample plots,it was found that the land used for planting poplar trees was mainly non-forestry land,especially farmland.The stability of the poplar forest resources was poor because most of poplar trees were cut down within 10 years after they were planted.Consequently,the poplar forest land was mainly transformed into the non-forestry land,especially farmland.And the above-mentioned transformations happen very frequently.In this article,the influence on forestland stability with the forest renewing and felling is explored and it has important significance to scientifically guide the management and cultivation of forest resources.

Key words: poplar, resource stability, cutting and renewing, forest inventory, permanent sample plot
