雾霾及地下水土壤污染的地质作用

Effects of Geological Factors on the Formation of Fog and Haze and the Pollution of Underground Water and Soil

导致雾霾、地下水和土壤污染的机理复杂,且影响因素较多。不同行业和学科研究的成果各有说法和道理,并且取得了一定的成效。但是,就目前的研究成果和实际情况来看依然存在着许多不攻自破的"漏洞"和片面性。通过2年来的野外调查研究和大量文献资料分析认为:雾霾的产生和土壤、地下水体污染主要由地质作用(构造活动和地球深部气体释放、煤田火区)、人类活动(地表到大气对流层空间)和气候气象(湿度、风力和降雨强度)3大因素造成。其中,地质作用是不可忽略的重要因素,也是难以预测和治理难度最大的。华北平原正好同时满足上述3个条件,处于雾霾严重区域。

The mechanisms are complicated in the formation of fog ＆ haze and the pollution of groundwater ＆ soil with many influence factors, the different viewpoints and arguments from different industries coexist; however, some of the views are of obviously one-sidedness. In this paper, with the field investigation in the past 2 years and based on a large number of reference literatures, the analysis shows that the formation of fog ＆ haze and the pollution of groundwater ＆ soil are caused mainly by 3 factors： geological processes （the tectonic activity, gas release from the deep earth and coalfield fire area） , human activities （from the surface to atmospheric troposphere） and meteorology ＆ climate （humidity, wind and rainfall in- tensity）. Among them, the important geological processes cannot be ignored, which are difficult to be predicted and con- trolled. With the above 3 influence factors, North China plain is just in severe fog area.
