摘要:

摘 要:本文以道孚县甲斯孔林场为例,基于1989年、1999年TM影像和2007年SPOT5影像数据,研究了遥感技术在川西天然林资源监测中的应用,分析了1989年至2007年甲斯孔林场天然林的动态变化过程。结果表明:1989年至1999年间,因天然林被大规模采伐,森林资源遭到严重破坏,森林覆盖率下降了3.52%;1999年到2007年间,由于天然林保护工程的实施,天然林资源有所增加,森林覆盖率上升了4.15%。由此说明,在天然林保护工程的驱动下,川西地区的天然林资源有逐步回升的趋势。关键词:遥感 天然林资源 天然林保护工程 甲斯孔林场中文分类号:S757.2 文献标识码:A

Abstract:

Abstract:The application of remote sensing in monitoring the natural forest resources in western Sichuan was researched with the case study of Jiasikong Forest Farm in Daofu county. The dynamic changes of forest resources in the farm were analyzed based on the TM images(1989,1999)and the SPOT5 image(2007).The results demonstrated that the forest resources had been seriously damaged and the forest coverage rate had dropped down by 3.52% since 1999 to 2007, as a result of the large-scale cut of the natural forest. While it had been remarkably restored with a rise of 4.15% of the forest coverage rate reported in 2007, because of the implement of the Natural Forest Protection Project(NFPP) started in 1998. It showed that the natural forest resources in western Sichuan province appeared to be restoring by the promotion of NFPP.
