摘要
鄂尔多斯风沙滩地区,常年干旱少雨,蒸发强烈,地下水资源消耗主要源于表土蒸发。而土壤凝结水的形成与转化又与表土蒸发之间存在着十分密切的关系。作者在内蒙古自治区乌审旗气象局院内,采用自制的笼屉式测渗仪进行土壤凝结水的观测试验研究,测量方法为称重法。并同步观测地表以上50cm处的空气温湿度以及地表和地表以下5cm、10cm、15cm、20cm、30cm、40cm、50cm处的土壤温度。通过试验,初步探明了该区土壤凝结水的形成与转化的基本过程,以及土壤凝结水的转化与气象因素之间的相关关系。
The windy beach area of Ordos is often arid, rainless, and intense evaporation. The consumption of groundwater resources is mainly evaporation of surface soil. Formation and conversion of soil dew is close relation with evaporation of surface soil. At weather bureau of Wushen County in Inner Mongolia municipality, the author did the observation experiment of soil dew by adopting self-made longti-microlysimeter, the measuring method is weighting one. Meantime, the author observed temperatures and humidity of 50cm、 100cm、 150cm、 200cm above the earth＇s surface ,and soil temperatures 5cm、10cm、15cm、20cm、 30cm、40cm、50cm below the earth＇s surface. Through the experiment, the basic process of formation and transform is primarily proved, and the relation between conversion of soil dew and weather factors provides some basic technique parameters for evaluation of the present groundwater resource.
