Abstract

Abstract:

The occurrence and development of salty soil diseases mainly depends on the temperature and humidity in cold and arid regions. In order to comprehend the variation pattern of temperature and humidity for saline soil of Hexi corridor, Gobi saline soil in Guazhou, Gansu Province was selected to monitor by thermo-sensitive probe and time domain reflectometry (TDR) during winter and summer. Based on the monitoring data, we knew that the soil temperature presented as sinusoid variation by a daliy or annual cycle, and the shallow soil temperature varied greater than the deep soil. With the depth increasing, not only the temperature amplitude decayed exponentially, but also the hysteresis increased proportionally. At a certain depth, soil temperature came to almost constant, the depth for daily was 40-50 cm while the depth for annual was 500-600 cm. Because of the large evaporation precipitation ratio and distant groundwater, there was no water supplied or lost in soil, which brought about an invariable humidity for soil, only a microvariation in shallow by the rainfall. It was considered that there was a probability for the salty soil diseases occurred in depth of 100-150 cm, which depended on the humidity of soil largely, so the waterproof and drainage should be enhanced on ground surface.

Key words: Hexi Corridor, cold and arid regions, saline soil, temperature and humidity, variation pattern
