中文摘要：

自然环境组成要素中没有一个要素与地貌形态无相互影响,人类的任何一个生产活动也与地貌形态具有密切联系.以新疆开都河流域地貌形态为研究对象,探讨流域尺度地貌形态类型、不同地貌形态的空间变异特征.在开都河流域实地考察、制图分析、对地貌形态分类和测定不同地貌类型的面积和相对高度、各地貌类型相互影响的数据基础上,采用地貌类型学和地统计学的方法,对研究区的地貌形态进行了制图分类及其特征变异分析,并采用GIS定位测定方法,做出开都河流域的地貌类型空间数字地图.结果表明：开都河流域地貌形态复杂多样,虽然开都河流域是以天山山脉中段南麓的山间盆地——焉耆盆地为中心,但是在流域中陆地上的地貌类型均有分布.该流域是典型的封闭性盆地地貌为主,多种地貌形态并存而交叉分布;该流域由三个盆地地貌单元组成,表现出山间盆地地貌类型的环状分布特点.

英文摘要：

In natural environment,there is not a natural environmental element which is not interaction effect with landform; any production activity of human also has a close connection with landform. In this study,landform features in the Kaidu River basin of Xinjiang are taken as a research object,to investigate the landform types of basin scale and spatial variability of different landforms. On the basis of investigation,the classification of landform types,the measure of the area of different landform types and the mutual effect between landform types,using the geomorphic typology method and geo-statistics,the spatial variability characteristics of the study basin＇s landform are analyzed. Using the method of GIS positioning,a digital landform map of the Yanqi Basin is drawn. It is found that（ 1） the Yanqi Basin landform is very complicated. Although the Kaidu River basin is an intermountain basin,which is located in the middle part of the Tianshan Mountains,the basin possesses all the terrestrial landform types;（ 2） the basin is a typical closed basin with various landforms cross-distributed;（ 3）the basin is composed of three basin geomorphological units,showing an intermountain basin landform types,characterized by annular distribution.
