Abstract:
The Mann-Kendall method was used to analyze the trend variations and mutations of annual average temperature and precipitation based on the meteorological data of Xinmi City from 1971 to 2000. The anthropogenic driving forces affecting the variations of temperature and precipitation were determined by the socio-economic data collected from 1981 to 2008. The gray relational analysis was used to characterize the interannual variability of impact strength of human activities and the temporal variations of anthropogenic driving factors before and after the temperature mutation. , and therefore the anthropogenic driving factors affecting the climate change can be analyzed and identified. The results indicated that the annual and seasonal atmospheric temperatures increase with a temperature mutation in 1993 while the annual precipitation has significant increasing or decreasing trends. The rapid growth of population density is the primary driving force of the temperature change in Xinmi, and followed by the agricultural development and energy consumption.
