【摘要】 在森林资源二类调查中,分别采用地形图或航片的传统方法和航天遥感图像资料(TM)的方法进行对比分析,从森林资源二类调查中的林地小班区划调查,蓄积量实测调查,生长量、消耗量调查,图面资料绘制等步骤进行了分析,并从2种方法的工作量、费用及效率等多方面进行比较。结果表明,利用“3S”技术进行森林资源二类调查较传统方法工作量、劳动强度减少,费用减少,可以大幅度降低调查成本,提高效率,各地类界线准确,从而提高了调查精度。利用“3S”技术进行森林资源二类调查有着广阔的应用前景。更多还原

【Abstract】 The traditional method and the spaceflight and remote sensing technology method of the second type inventory of forest resources are contrasted in this paper. From the land bottom class investigation, store quantities investigation, growth quantity, the consumption investigation and pattern material plan and so on steps of the second type inventory of forest resources are analyzed. The two methods of the workload, costs and efficiency, and other aspects of are compared. Using the "3S" technology for the second type inventory of forest resources the workload, labor intensity and the cost are reduced than using traditional methods, It can large scale reduce the investigation cost, enhance the efficiency , various terminations line is accurate, thus increased the investigation precision. Using "3S" Technology carries on the second type inventory of forest resources have the widespread application prospect.更多还原
