【摘要】 通过选取甘肃省景泰县两个时段的卫星影像并经过加工处理,分析比较两个时期该区域的植被变化情况和土地利用变化情况,并计算出两个时段的具体数据,从该县近年各项林业工程建设任务的角度分析土地利用变化和森林消长的原因,首次尝试应用美国TM遥感卫星影像和法国SPOT卫星影像结合调查三北防护林的监测管理。通过该例研究和分析,为在三北工程建设区大面积推广应用遥感数据进行工程监测和管理提供有益的探索和实践。更多还原

【Abstract】 By processing two selected time-phases images of Jingtai county,Gansu Province,the changing of vegetation and land utilization of target areas were analyzed, and the concrete data in the two time-phases were calculated.Meanwhile the causes of the change of land utilization and fluctuation of forest resource were analyzed from the construction tasks of various forestry projects in the county in recent years.The TM and SPOT remote sense images were first applied in monitoring and managing the "Three-North" Shelterbelt Program.This study provided useful exploration and practice for extending the application of RS data in monitoring and managing forestry activities in the construction area of "Three-North" program.更多还原
