| 摘 要： | 在平原微丘区,丘陵、平原界限的确定是地貌图制作的难点.本文首先指出,地貌的多样性和地区差异性决定了地貌分类的量化指标差异性,通过对比实验,制定一套合理、有效的丘陵、平原量化分类标准.在此基础上,以江苏省1:50 000比例尺25 m分辨率DEM为基本数据源,对全省平原、丘陵进行了划分.通过自动制图综合,完成了江苏省地貌类型图制作.实验结果显示,所提出的分类指标简单、实用,该方法大大提高了丘陵岗地划分效率与精度.

| Abstract: | The definition of the margin between plain and hill remains a difficult problem in the process of mapping in plain and micro hill regions.This paper proposes that both the diver-sity in geomorphology and discrepancy in different test areas determine the difference of quanti-tative indices in terrain classification.The paper proposes a reasonable and effective classifica-tion method in terrain classification based on DEM through compared experiments.Using 1:50 000 scale DEM data with 25m resolution as data s... |
