摘  要:
以2002年和2006年TM遥感影像为数据源,在PCI 8.5和ARCGis 9.2遥感图像处理软件的支持下,获得了鄂托克前旗2个时期的森林资源图。通过计算机自动分类和分类后人工解译纠错相结合的图像分类提取方案,提高了图像分类提取的效率和精度。动态监测结果表明,从2002~2006年,面积增加的地类为灌木林和有林地,面积减少的地类为宜林地和裸沙地,农田和水体的面积基本保持不变,并对其变化结果进行了分析。

摘  要:
Taking 2002 and 2006 TM images of Etuoke Qianqi as data sources,forest resources maps in two periods were obtained supported by PCI 8.5 and ARCGis 9.2.The imagine classification efficiency and accuracy are increased by combining with automatic classification of computer and post-classification of manual interpretation.The results after dynamic monitoring show: from 2002 to 2006,the land types with increasing area are shrubland and woodland,the ones with decreasing area are suitable land for forest and sandy land,the area of farmland and water mass remains unchanging.And the variable result is analyzed and discussed.
