敦煌鸣沙山月牙泉景区风沙环境分析

摘要/Abstract

摘要： 基于月牙泉周边7个气象站点同步风况资料,探讨月牙泉周边起沙风况、输沙势以及主导输沙方向的空间分布特征。结合月牙泉周边沙山、建筑物、树木等的方位特点,剖析了近年来月牙泉受沙害困扰的缘由。由于受南北两高大沙山的夹击,该区北风相对较少,西风和南风较强,南侧沙山的北移最为突出,直接威胁月牙泉的存亡。

Abstract: Based on wind data in a scenic spot of the Singing Sand Mountain & Crescent Moon Spring, the spatial patterns of sand-laden wind, drift potential and dominant sand-transporting orientation were investigated. Together with the spatial pattern characteristics of sand mountains, buildings and trees around the Crescent Moon Spring, the reason of sand encroaching to the Crescent Moon Spring was revealed. North wind was relatively scarce in the Crescent Moon Spring because of blocking of sand mountains to the south and north of the Crescent Moon Spring, and the dominant winds were from west and south. Sand mountains to the south of the Crescent Moon Spring moved toward north obviously. The results are useful to reveal the characteristics of sand damage to the Crescent Moon Spring and to provide theoretic base for controlling sand damage to the Crescent Moon Spring.

Key words: sand-laden wind, drift potential, sand-laden wind rose, the Crescent Moon Spring
