Abstract

This paper chooses precipitation and temperature data from 106 stations in the Northeast of China from 1951 to 2007.By using time series analysis, Kriging analysis and other mathematical methods, combined with geographic information system technology, we analyzed precipitation and temperature change on a time and space of this region during nearly 60 years. The results show that the average temperature in the northeastern region exhibits an increasing tendency during nearly 60 years. The average temperature has stage characteristics. Temperature fluctuation was greater between 1951 and 1970. The temperature was mainly on the rise between 1971 and 1988 but the change range was relatively small. Since 1989, there appeared significant warming process and the trend was obvious. On the precipitation change, precipitation was decreasing tendency on this area and had bigger fluctuation. The period (1951-1970) is rainy period. The period (1971-1988) is less rain period and annual fluctuation range of precipitation is not big. Since 1989, annual fluctuation range of precipitation was relatively large. The period since 2000 was obvious less rain period. In the spatial distribution, the temperature change range was gradually strengthened from the southwest to the northeast between prophase and middle. Changes of precipitation have different degree decrease in most northeast area except northern mountain area. The temperature change range was gradually strengthened from the southeast to the northwest between middle and late. Precipitation changes range in the northern mountain of the area is smaller, while the western and south-western plain areas have larger precipitation change range.
