山东杨树资源变化及原因分析
|
摘要
利用山东省第四至第九次森林资源清查固定样地数据,通过对比分析其杨树样地前期清查和后期清查之地类、树种及其年龄等的变化,研究得出山东省杨树造林地主要来源于非林地特别是耕地,且杨树资源稳定性差,多数树龄不到10a就已经采伐更新,或转变为非林地、耕地,林地、耕地间隔转移变化频繁。探索了更新和采伐规律对林地稳定性的影响,对科学指导森林资源经营和培育有重要意义。
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.
