Effect of Soil Moisture Content in Farmland Surface on Dust Release
摘要
Abstract
In order to simulate accurately the farmland dust emission flux in Northwest of China, DPM model is made on the appropriate amendments. The relationship between the DPM model values and the field observations under different simulated water content is analyzed. The value of DPM model improved by the wet soil threshold friction velocity model is calculated and analysed. By comparing the values of DPM model improved by the wet soil threshold friction velocity model, the Shao Yaping threshold friction velocity model is more suitable for modified value of soil moisture to DPM model in northwest of China. Being amended, the DPM model simulate values and the observed values converge.关键词
