天山北坡绿洲空间运动的历史与现实模式

The Historical Mode of the Spatial Movement and the Transition Tendency of the Oasis at Northern Foot of the Tian Mountain—Also Discussing the Classification of Oasis in Xinjiang

以天山北坡绿洲为对象,研究了绿洲空间结构运动的历史模式,分析了现代空间结构运动特点,得出以下认识:①从原始绿洲到现代绿洲,绿洲空间运动的基本模式有空间位移、空间扩张和点—轴运动,均围绕“水轴”展开。②现代绿洲内部空间结构运动的轴线由纵向“水轴”与横向“陆桥轴”组成“十字坐标”“双轴”构型,空间结构的“支点”增多。③绿洲内部空间结构运动与外部临近绿洲运动具有协同特点。图2,参12。

Taking the oasis at the northern foot of the Tianshan mountain as a case, this paper studies the historical basic modes of the spatial structtrre by using history data, analyzes the character and the tendency of the contemporary spatial structural movement, then concludes as follows：（1）from the primeval oases to contemporary ones, there are three basic patterns of spatial movement,which include spatial displacement, spatial extendedness and node-axis structure.The primeval oases to contemporary ones, oases movements base on a basic middle axis-rivers, that is, water-axis. （2）In a contemporary individual oasis, the longitudinal ＂water-axis＂ and the horizontal ＂overpass axis＂ form together a new spatial structure termed＂ cross coordinate＂. And the fulcrums of economic spatial structure have increased.
