Abstract

This paper aims to enhance the research on drought in Jiaodong Peninsula, to provide reference for local government to establish the policy of drought resistance and disaster reduction, and to reduce drought impact. According to analysis of temperature and precipitation data from 1971 to 2012 at 24 meteorological stations in Jiaodong Peninsula, the variation trends of meteorological factors are statistically analyzed and drought in Jiaodong Peninsula is evaluated by analyzing the De Martonne Aridity Index. The results show that the annual and the seasonal average temperatures are rising significantly, while precipitation variation is not significant, which shows an increase trend in spring and summer and a decrease trend in autumn and winter. The cases above cause that the number of occurrences of the middle drought will increase while that of the heavy drought will reduce. The De Martonne Aridity Index can be used to describe the drought in Jiaodong Peninsula in a certain extent, but it is not applicable in some cases.
