| 摘 要： | 为准确模拟陕西中北部地区农田地表粉尘释放通量，对DPM模型做了适当修正。对比分析了不同含水率下DPM模型模拟值和野外观测值的关系，计算分析了利用各湿土起动摩阻风速模型改进后的DPM模型模拟值。结果表明：使用邵亚平起动摩阻风速模型修正陕西中北部地区农田土壤含水率对DPM模型模拟值的影响较适合，修正后DPM模型模拟值和观测值趋于一致。

| 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 mode... |
