地貌基本形态的位差分类法

The Position and Altitude Classification of Geomorpholgic forms

针对现有地貌基本形态分类法的欠缺,本文提出了“地貌基本形态的位差分类法”。本分类法是一种以相对高度为主绝对高度为副的地貌分类法,它首先根据相对高度将地貌基本形态分平原、丘陵、低山、中山、高山等,然后再按绝对高度把这些形态再分别划分为低位、中位、高位三种类型。该地貌分类法的优点在于:①该分类法符合人们对于山地的高、中、低的观念,避免了现有地貌分类法中出现的那种与人们固有观念相冲突的高山不高、低山不低的现象;②统一了地貌基本形态的划分标准,避免了平原、丘陵按相对高度划分、山地按绝对高度划分的不一致性;③有利于地貌知识的科学普及和地貌的生产利用。

According to the fact of shortcoming in existing geomorphologic classitic-tion, the paper puts forward the 'position and altitude classification of geomorphoiogic forms. ' It is a kind of classification which takes the relative altitude as a main element and the absolute altitude as a subelement. It uses the relative altitude dividing the geomorphoiogic forms into plain. hills, low mountain, middle mountain, high mountain at first, and then uses the absolute altitude dividing these forms into low position middle position and high position respectively. This geomorphoiogic classification there are more advantage :①The clas-sificaton is keeping with the people's concept of looking on mountains;②It standardizes the standard of the geomorphoiogic classification; ③It is favourable to popularize and utilize the geomorphoiogic knowledge.
