Abstract

Abstract: Many researches have proved that temperature has ascended. It is known that temperature is closely related with living beings. Because the amounts of plants and animals are reduced sharply, the trend of temperature becomes the research hotspot under the natural and human impacts. Based on the temperature data of 117 meteorological stations from 1970-2007 in Shandong Province, R/S analysis in fractal theory is adopted to research the changing trend in temperature. Then GIS technology is employed to study the characteristics of temperature change in recent 40 years. The results show that the chance in which H index is not equivalent to 0.5 is 100%, demonstrating the temperature of this province is changing trend. Temperatures of spring, summer and winter will keep a rising trend. The distribution of isothermals turns to be random and the local microclimates will develop which can be partly explained by human influence.

Key words: fractal theory, GIS technology, isothermals, Shandong Province
