| 摘 要： | 采用成数抽样方法，利用平顺县１∶１万地形图，对平顺县典型的２１９条沟叉（每个沟叉为一封闭的小集水区）进行了不同土层厚度的地块面积比例调查。将调查资料，按海拔梯度进行分组，统计每个沟叉不同土层厚度不同坡向地块的面积。用加权平均法，计算了同一土层厚度同一坡向地块占沟叉总面积的百分比。进而求算了各海拔梯度组合立地的面积，并对此次调查精度做了验算

| Abstract: | Areas of hilly lands with different thickness of soil from 219 typical gullies in Pingshun county were investigated with percentage sampling method on a topographic map(1:10000),classfied on elevation,and then counted up on different soil thickness and slope aspect for each gully.The weight average percentage of areas of sites with same soil thickness and same slope aspect to the gully's area,and the areas of sites for each elevation were counted The precision for this investigation was given at last. |

| Keywords: | limestone mountainous region site groups gully sampling for percentage |
