中文摘要	选取青海省、甘肃省、宁夏回族自治区、新疆维吾尔自治区、内蒙古自治区和西藏自治区19801995年和20102019年两段时间的逐日地面气象要素和逐月降水量等要素确定西北干旱荒漠区理论范围,基于该区域逐月降水量估算多年平均降水量,通过Penman-Monteith公式计算潜在蒸散量,获得湿润指数空间分布;最后将多年平均降水量与湿润指数进行叠加分析,识别西北干旱荒漠区的边界。结果表明:形成了南起昆仑山脉,北至阿尔泰山脉,西至贺兰山的西北干旱荒漠区范围,但天山北麓、乌鲁木齐绿洲、伊犁河谷和塔城部分地区除外;通过对研究区2个时间段数据的对比,明确了西北干旱荒漠区范围变化是由于降水量及潜在蒸散量低的地区明显减少和湿润指数高的地区明显增多导致的,发现干旱区分界线明显北移,半干旱区面积明显增大;区划结果与山系相结合将西北干旱荒漠区范围划分到区县级,为西北干旱荒漠区的资源开采利用、因地制宜的生态修复提供了一定的数据支撑。
英文摘要	Starting from the qualitative description of arid desert areas in northwest China, a quantitative and precise boundary is formed based on the daily surface meteorological elements and monthly precipitation in Qinghai Province, Gansu Province, Ningxia Hui Autonomous Region, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, and Tibet Autonomous Region in 19801995 and 20102019. The arid desert area in northwest China was determined, the potential evapotranspiration was calculated using the Penman- Monteith equation, and the spatial distribution of the wettability index was obtained. Finally, the average precipitation and wettability indexes were superimposed, and the boundaries of arid desert areas in the northwest were identified. The results showed that the arid desert areas range from Kunlun Mountains in the south to Altay Mountains in the north and the Helan Mountains in the west, except for the northern foot of Tianshan Mountains, Urumqi Oasis, Ili River Valley, and parts of Tacheng Prefecture. A comparison of the data of the two periods in the studied area clarified that the change in the scope of the arid desert area in northwest China is due to the obvious decrease in precipitation and potential evapotranspiration and the obvious increase in the area with a high humidity index. The dividing line of the arid region moved northward and the semiarid region increased evidently, and the arid desert region in northwest China was divided into districts and counties based on the results of the division and mountain system, providing data support for the exploitation and the utilization of resources and ecological restoration in the arid desert area of northwest China. This work is of great significance for regional refinement, exploitation, and utilization of resources; ecological restoration according to local conditions; the development of the northwest economy; and scientific research.
