RELATIONSHIP BETWEEN REGIONAL SOIL MOISTURE VARIATION AND CLIMATIC VARIABILITY OVER EAST CHINA

Based on the data of soil moisture, precipitation and temperature every ten-day over the east of China from 1981 to 1991, their trend, interannual variability and relationship among them were analyzed. The results indicate the notable trend of soil moisture, precipitation and air temperature, positive correlation between soil moisture in every layer and precipitation, and negative correlation soil moisture and air temperature can be found, the correlation coefficient reaches the testing of degree of confidence of 0.01.Also the results mean the data is useful for analyzing the relationship between soil moisture and climate change.
