摘  要:
草地资源遥感开拓了草地科学的一个新领域,应用电子计算机数字图象处理技术进行草地资源管理将是今后的发展方向,但目前尚难在生产中大量使用,因此,提高目视解译技术,将其由定性分类发展到定量分析是提高和普及草地资源遥感技术的重要任务。1983年,我们在河北省和内蒙古自治区应用陆地卫星影象目视解译抽样技术进行了草地资源调查,编绘了草地类型图,计算了各类型草地的面积,估测了草地生产力,取得了较好的效果。

摘  要:
A study of application of landsatimagery to grassland resource surveys was carried out on the Inner Mongolia Antonomous and Hebei Province in 1983.The total area was 34225 sq.km.,and it was covered by《Guyan Landsat Imagery》.The interpretation symbols of landsat imagery was been set up,and the map of grassland types was been reaped by useing visual interpretation techniques.Frequecy sampling in 95% of Veliability and 90& of accuracy were carried out in the landsat imagery survey of grassland resources.The area of different types was been calculated.combining the interpretation resuhs of landsat imagery with plots of measured on ground,the density of stocking on grassland was been estimated.
