本研究以陕北黄土高原大岭林场为研究对象,以1999和2006年两期TM/ETM＋影像为主要数据源,结合森林资源调查数据,分析了该林场森林资源时空动态变化。结果表明：1999～2006年间,耕地和疏林地分布面积减少,阔叶林地、针叶林地、混交林地和灌木林地面积比例均有增加,充分说明天然林保护工程有利于森林资源的更新和林场的可持续发展。通过马尔科夫预测,2006～2013年变化动态最大的是疏林地,其次是灌木林地、阔叶林地、混交林地、耕地和针叶林地。

Taking Daling forest farm as an example,this paper analyzed the spatial-temporal change of forest resources using TM in 1999 and ETM+ in 2006 as main data source,and survey data as assisted.The results showed that the farmland and open forest land decreased,and broad-leaved forest land,coniferous forest land,mixed forest land and shrub land increased during the period 1999-2006,indicating natural forest protection project benefiting the regeneration of natural forest resource and the sustainable development of forest farm.The biggest changes occur in open forest land,and followed by shrub land,broad-leaved forest land,mingled forest land,farm land and coniferous forest land.
