摘要
The trend analysis method was adopted to study the spatial distribution and change trend of temperature,rain,rain days,extreme rain case and extreme temperature based on meteorology data of 48 ground stations in east of Inner Mongolia from 1951 to 2005.The results showed that temperature of east of Inner Mongolia was improving,and improving degree of extremely minimum temperature was higher than extremely maximum one.Rain of east of Hulunbuir and southwest of Chifeng was more markedly improving and was most markedly decreasing in Tongliao.Rain days were decreasing at majority area,while increasing at southwest,east and north of Hulunbuir.The one which was above 25 mm showed an increasing tendency.
