对森林资源调查中合理区划小班的探讨

Survey on the Rational Division of Small Classes of Forest Resources

森林资源调查中,小班是很重要的的区划单位,也是森林区划的最小单位。区划的合理与否会直接影响到小班的调查精度和质量,从而影响整个外业调查精度,对指导林区的合理化经营起到至关重要的作用。本文通过对遥感影像(包括航空照片)上具有同一色调、纹理等一致性的影响特征的研究,提出了小班区划的合理性操作方法。

The small Class is the most important and smallest division unit in the survey of forest resources.Weather the division is rational or not may affect the accuracy and quality of the investigation,thus affecting the accuracy of the field investigation.The paper poses to divide small classes by the features of forest resources such as their colors and veins,based on the remote sensing techniques(including aerial photos).
