摘要
以数值模拟与大规模网络观测的对比结果为基础,通过对“去除”已经沙化土地获得的近地面层粉尘浓度的进一步分析,结合已获得的亚洲沙尘暴各源区粉尘释放量结果,提出我国的人为沙漠化因素对亚洲沙尘暴的贡献约为6%的观点。
On the basis of simulations of emissions and surface concentrations for Asian dust along with validations from a network observation, the anthropogenic related desertification areas within China contribute only about 6% increasing to Asian dust storm. This idea is also derived from the re-assessment of sensitivity test for dust concentration reduction by removing the desertification areas, and simulated dust emission fractions from different Asian dust sources.
