| 摘 要： | 利用中国100°E以东地区98站共11a的旬土壤湿度、降水和气温资料，对不同区域土壤温度、降水和气温的变化趋势、年际变率及它们之间的相互关系进行了详尽的分析。结果表明：土壤湿度、降水和气温有较明显的变化趋势；土壤中各厚度层土壤湿度和降水的关系呈正相关关系，与气温呈反相关关系，且可通过0．01的置信度检验。这也说明现有土壤湿度观测资料在研究气候变化中的有效性。

| Abstract: | 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 soll moisture, pre-cipitation 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. Al-so the results mean the data is useful for analyzing the relationship between soil mois-ture and climate change. |
