Just decades earlier, in the 1870s, the state had begun taking over parcels of cutover land forfeited for nonpayment of taxes.
就在几十年前，18世纪70年代，联邦政府开始接管那些因拖欠税款而丧失使用权的砍伐迹地。obvious dynamic change has been occurred, such as 55. 5% of cutting land was covered by Chinese pine and 21. 1% was covered by poplar.
林地类型之间发生了明显的动态变化，其中，55.5%的采伐迹地变成了油松林地，21.1%的采伐迹地变成了杨类林地。Study on the Morphological Characteristic of the Wind-damaged Slash in the Restorable Community of Jinyun Mountain Nature Reserve
