半湿润地区农田土壤粉尘释放的风洞模拟研究
, PP. 1364-1369
Keywords: 土壤风蚀,农田粉尘释放,风洞模拟,半湿润区
Abstract:
采用风洞模拟手段对地处半湿润区的北京市农田土壤风蚀中的粉尘释放规律进行研究。结果表明,研究区农田粉尘释放强度随风速增大呈指数规律增大,粉尘在风蚀物的含量随风速增大呈指数规律降低。近地表粉尘质量流量随高度增加呈幂函数规律降低,在风蚀物中的含量随高度增加呈线性增大。粉尘粒径随风速增大而变粗,之后达到稳定状态。近地表粉尘粒度组成沿垂直方向的变化可以划分为两段,0~20cm高度层的双峰态分布和20~60cm高度层的三峰态分布。随着高度增加,释尘粒度组成变细。
