柴达木盆地东南部雅丹地貌形态参数研究
Morphological Parameters of Yardangs in Southeastern Qaidam Basin
摘要
Abstract
The external morphology of Yardangs reflects the settings they exist.Therefore,through the study of Yardangs＇ morphological parameters,the interior and exterior forces that affect the Yardangs can be speculated.This paper mainly studied the morphological parameters of the Yardangs that distributes in the southeastern Qaidam Basin with data from the high resolution remote sensing images of the study area,and found that the correlation index between length and width was 0.882 4,a strongly positive correlation;the ratio of length/width calculated by least square fitting was 3.04.What＇s more,the worldwide Yardangs＇ morphological parameters shared the same strong positive correlation,while the ratio of length/width showed a regional difference.This phenomenon was tried to be explained on the basis of the forming factors of the Yardangs.It is believed that the similarity of the forming factors determined the similarity of the external morphology of the yardang body,which was reflected by the strong positive correlation between the length and width.At the same time,because of the regional differences of the Yardangs＇ forming factors,the ratio of length/width had different values in different places.关键词
