摘要
实践表明，应用航片法进行土壤普查与制图可以加快土壤普查速度，减少野外工作量，降低成本，提高经济效益；提高土壤制图的精度；节省测制地形图，地块底图的工作量。但航片的判读需具备广泛的专业知识和丰富的判读经验，同时航片也缺少某些定量指标。本文着重剖析航片法进行土壤普查与制图的利弊。
In the course of explorratory soil survey,the aerial image can raise the velocity of mapping of soil and soil investigation,lighten field work,and it can reduce cost,raise economic efficiency,save some work of investigating the base map of land block,But the aerial photointer pretation short of exact scale,if need professional knowledge and experience.
