Changes of Soil and Temperature and Humidity of Air among Various Types of Degradation in Daxing’an Mountains
Scrub and Quercus mongolica in south-facing slope and temperature and humidity of soil and air in north-facing slope in Daxing’an Mountains were determined by adopting soil and air automatic recorder.Result shows that the descending order of soil temperature is grass > bush-grass > Quercus mongolica forest > north-facing slope;average value of growing season in hassock is 6.01 degrees higher than that of the north-facing slope;the soil mois-ture is opposite to the soil temperature,which shows that the north-facing slope > Quercus mongolica forest >bush-grass> hassock,among of which north-facing slope is 78% higher than that of hassock;the difference of three kinds of temperature and humidity of air is small,these show that the change of temperature and humidity of soil are the important factors influencing the vegetation restoration of dry south-facing slope.
