根据山东省17个气象站1970~2007年的气温资料,利用R/S分析法研究了气温的变化趋势.结果显示:近40a来,山东省十七城市气温呈现出明显的升温趋势,其中冬季气温趋势倾向率最大,其次为春季,夏秋两季气温趋势倾向率比较小.Hurst指数和气温趋势倾向率之间存在明显的线性相关关系.但城市化水平与年气温趋势倾向率之间并不是简单的线性相关关系.
THE ANALYSIS OF TEMPERATURE TREND IN PROCESS OF URBANIZATION
Based on the temperature data from 17 representative meteorological stations in Shandong Province from 1970 to 2007, the tends of the temperature change were analyzed by R / S analysis,. The results showed that the temperature of the 17 cities in Shandong Province increased clearly in recent 40 years. The rate of temperature trends in winter was the highest and then was followed by the spring. That of the summer and autumn was relatively lower. The linear relationship exists between the Hurst index and the rate of temperature trends.The relational model between the level of urbanization and the rate of the temperature trends was not the simple linear regression.
