摘要:

针对鸣沙山月牙泉景区南北沙山相向移动威胁月牙泉存续的问题,景区服务中心于2012年实施风道疏通工程,但截至目前尚未评估工程对区域风动力环境的影响。鉴于此,本文基于景区内布设全自动气象观测仪所获取的2009—2025年气象数据,统计平均风速及频次并计算输沙势,探讨景区风动力环境对风道疏通工程的响应。结果表明:(1)观测点年平均风速呈波动上升趋势,年平均起沙风速为下降趋势;(2)风向热力图表明近地表风速在空间上受疏通工程影响明显,风道疏通后对应风向年平均起沙风速增幅约为10%;(3)区域0~5 m·s-1风速区间占全年风速记录比例在90%以上,随着风速等级升高,对应比例下降;(4)风道疏通工程影响着对应方向输沙势,2013—2017年工程实施期间,对应风向输沙势增大。综上可知风道疏通工程对景区风动力环境恢复有着积极作用。

Abstract:

In response to the threat to the survival of Crescent Lake posed by the convergent movement of the southern and northern sand dunes in the Mingsha Mountain-Crescent Spring Scenic Area, the scenic area service center implemented a wind corridor dredging project in 2012. However, the impact of this project on the regional wind dynamic environment has not been evaluated to date. In view of this, based on meteorological data collected from 2009 to 2025 by the automatic meteorological observation instruments deployed within the scenic area, this study analyzes average wind speeds, wind frequency, and drift potential to evaluate how the local aeolian dynamics have responded to the wind corridor project. The results show that: 1) The annual average wind speed at observation sites exhibits a fluctuating upward trend, while the annual average sand-driving wind speed for sand entrainment shows a declining trend; 2) The wind direction heat maps indicate that the near-surface wind speed is significantly affected by the dredging project in terms of spatial distribution, with the annual average sand-moving wind speed in the corresponding wind direction increasing by approximately 10% after the implementation of the wind tunnel dredging; 3) The proportion of wind speed ranging from 0 to 5 m·s⁻¹ accounts for more than 90% of all recorded wind observations annually, and the proportion decreases as wind speed increases; 4) The wind corridor dredging project has an impact on the drift potential in the corresponding direction, with the drift potential in the corresponding wind direction increasing during the project implementation period from 2013 to 2017. Overall, the findings demonstrate that the wind corridor dredging project has positively contributed to restoring near-surface airflow patterns in the scenic area.
