摘　　要：以吐鲁番市高昌区为例,根据实测数据及遥感影像,综合应用Envi5.0、Arc GIS10.4.1等软件,通过空间分析与统计相结合的方式,从地形地貌蓄水能力、高程,坡度、耕地面积、土质等5个方面,系统分析了坎儿井空间分布格局的影响机制,得到如下结论:(1)地形地貌蓄水能力的强弱、耕地面积的大小,土壤质地都对坎儿井的分布数量及长度有影响;(2)吐鲁番市高昌区坎儿井以艾丁湖为中心呈扇形分布,坎儿井走向均指向艾丁湖方向;(3)坎儿井的高程、坡度则与数量、长度、流量成反比。In this paper, Gauchang District of Turpan City is the research area, according to the measured data and remote sensing images. Integrated application Envi5.0, AreGIS10.4. land other software tools, combined with the combination of spatial analysis and statistics. Based on terrain and geomorphic water storage capacity, elevation, slope, cultivated area and soil texture, the influence mechanism of the spatial distribution pattern of Karez is analyzed systematically. The results are as follows： The topographic and horizontal water storage capacity , the size of cultivated land and the texture of soil have effect on the number and length of the distribution of the Karez. Turpan City, Gaoehang District Karez regards Aiding Lake as the center assuming the shape of fans. The direction of the Karez is pointing to the direction of Lake Aiding. The elevation and slope of the Karez is inversely proportional to the quantity, length, and flow rate.
