中文摘要	通过研究不同时期半干旱地区农田地表粉尘释放特征,采用野外观测对比分析的方法,分析不同地表特征与地表空气动力学粗糙度的相关性、不同季节和不同地表土壤类型与地表粉尘释放的相关性,得到了半干旱地区农田粉尘释放通量.结果表明,半干旱地区裸露的农田中沙壤土农田地表粉尘释放通量最大,地表粉尘释放通量为 21-39mum·~(-2)·S~(-1);其次是壤土农田,地表粉尘释放通量为12 - 19mugmum~(-2)muS~(-1);黏壤土农田地表粉尘释放通量最小,在5-8mug·m~(-2)·S~(-1)
英文摘要	The present paper intends to introduce our study results on the dust emission of semi-arid area in China’s northwest. As is known,in recent years there has come a burgeoning interest in the study of atmospheric dust, most of which is generated by the deserts in the world. However, there has existed a huge uncertainty of the characteristic features of such emission and the relationship between the atmospheric mineral dust aerosol level and its radioactive intensity in addition to the likely influence of such dust emission on the human health. In order to know the situation of dust emission flux of semiarid farmland areas more accurately, this paper has made a detailed investigation over such dust emission in different times. Besides,we have calculated and analyzed the connection between different surface features and aerodynamic roughness by tracing and observing the correlation of such dust emission in different seasons and the different soil types in the region with the emission flux. The results of experimental research show that: the sandy loam soil proves to be the greatest source of exposed farmland surface dust flux in such areas. The actual emission flux lies in the range of 21 - 39 mug·m~(-2)·S~(-1), which is followed by the loam field, whose dust emission flux is in the range of 12 - 19 mug·m~(-2)·S~(-1); whereas the clay loam has the smallest ux, which is 5 - 8mug·m~(-2)·S~(-1)
