摘要
2014年底,广东省新兴县借助遥感数据并结合造林作业设计、采伐作业设计,在外业核查的基础上完成了年度森林资源档案更新工作。文章将2014年成果数据与上一年度档案更新成果数据进行对比,分析结果认为,2013~2014年间林地面积、生态公益林面积不变,主要蓄积树种仍为湿地松、马尾松等针叶树种,成、过熟乔木林占乔木林总蓄积的65.3%,比例相对较高。藉此提出相应建议。
At the end of 2014, the annual forest resources archive updating of Xinxing County has been done by using remote sensing data and combined with afforestation and logging operations design, also based on the field work. The comparison results of 2013 and 2014 concluded that forest area and ecologi- cal forest area were same from 2013 to 2014, the dominated accumulation tree still were wetland pine, Masson pine and other conifer species. Mature and over mature tree species was arbor which accounted for 65. 3% of arbor total volume, the proportion was relatively higher. Whereby, recommendations have been put forward accordingly.
