【摘要】：依据石嘴山和巴彦高勒水文站的输沙特性以及磴口站的水位变化,对乌兰布和沙漠风沙入黄量进行了评估,并基于沙漠风沙综合观测基地的长系列观测数据,计算了2013—2016年的风沙入黄量为53.78万~158.92万t/a;根据年平均风速估算了1954年以来的风沙入黄量过程,并设定未来情景模式,计算了2017—2036年的风沙入黄量。2014—2016年为1954年以来沙漠风沙入黄量的最小时期,在设定情景下,2017—2036年风沙入黄量仍有超过400万t的年份。随着沙漠治理力度的加大,2031—2036年风沙入黄量将下降至262.45万t/a。
[Abstract]:According to the sediment transport characteristics of Shizuishan and Bayangol hydrologic stations and the water level change of Dengkou station, the paper evaluates Wu Lan Buhe desert sand entering into Huang Liang, and based on the long series observation data of desert wind-sand comprehensive observation base,The sandstorm entering Huang Liang in 2013-2016 was calculated to be 537800 ~ 1.5892 million t / a. According to the annual average wind speed, the process of wind and sand entering Huang Liang since 1954 was estimated, and the future scenario model was set up.The paper calculates that the period 2017-2036 from the wind to Huang Liang. 2014-2016 is the minimum period of desert wind and sand coming into Huang Liang since 1954, and the year 2017-2036 is still more than 4 million tons.As desert control intensifies, wind and sand entry into Huang Liang will drop to 2.6245 million t / a in 2031-2036.
