图3 陡坡区采样偏移理论模型示意 注:依据斯特拉勒A.N.《自然地理学原理》,S>15%、α>35°为高能搬运区,偏移≤100 m可保障介质代表性(RD<20%)

Fig.3 Schematic diagram of the theoretical model of sampling bias in steep slope areas note: according to A.N. Strahler's "Principles of Physical Geography", S>15% and α>35° indicates a high=energy transport zone, and an offset ≤100 m ensures the represent-ativeness of the medium (RD<20%)
