四川省近20年天然林资源动态变化分析
|
摘要
利用四川省1997、2007、2012、2017年4期森林资源连续清查成果数据,以面积、蓄积、林分质量等为指标,从面积、蓄积结构,以及林分质量等方面研究了四川省天然林资源近20年间动态变化。分析表明:在过去的20多年间,四川省天然林资源无论从资源数量还是资源质量都整体呈现上升趋势,自1997年以来全省天然林面积增加152. 90万hm~2,蓄积增加2. 73亿m~3。天然林资源数量持续增加,质量持续提升,森林覆盖率大幅提升。
The dynamic changes of Sichuan natural forest resources in the past 20 years were studied on the basis of the aspects of area,accumulation and stand quality through the data of continuous forest resources inventory of 1997,2007,2012 and 2017. The analysis showed that the natural forest resources of Sichuan province presented an overall upward trend in terms of both the quantity and quality. Since 1997,the natural forest area has increased by 1. 529 million hectares and the volume has increased by 273 million cubic meters. The number and quality of natural forest resources are continuously to increase,and the forest coverage rate has significantly increased.
