- Abstract:
- By Using statistical regression methods and analyzing soil moisture and weather data of 3 meteorological observation stations for agriculture and animal husbandry of Hulunbeier city from 1988 to 2007, results showed that annual precipitation of Hulunbeier city changes were decline trends significantly, annual change rate ranged 8.275~10.347 mm/a, the average annual temperature was not obvious on the rise. The soil moisture content of 0-50 cm soil depth declined sharply at the rate of 3.816 2~0.723 6 mm/a year by year, reaching to significant or very significant level in the agricultural area and forest area, soil drought degree increased. The soil moisture was negatively related to the temperature from April to October and positively related to the annual precipitation significantly. The effects of climate change on soil moisture concentrated in the summer and fall seasons, reaching significant levels.
