| As an important component of the nature environment, climate is vital to human survival. Every change of the climate can make an effect on nature eco-system and social economy. The effect will be multi-scale and multi-level. As an important nature resource, also climate is the main component of nature environment. Therefore the effect on social economy system will be from two aspects. At different degrees, climate-change has affect on every aspect of global and regional social economy. Varying with the location, time, society development levels and the environment condition, the social system is sensitive and vulnerable to climate change. Thus the study on regional climate change and its character should be reinforced. It is vital to the making of region development policy and the eco-construction.Taking the Huaibei region of Anhui province for study area, this paper makes use of data of the weather stations in Huaibei region from 1953-2000.From aspect of space and time, the paper makes a comprehensive analysis on the climate change of Huaibei region with the help of GIS and mathematics methods such as wavelets, Kriging and so on. Also this paper points out the changing trends. From the latest 50 years, the development of the average of the annual temperature in Huaibei region has three stages. They are the periods of 1953-1971, 1971-1986, 1986-2001.In the first stage, the trend of the annul temperature decreases. In the second stage, the trend of the annul temperature increases. In the third stage, the trend of the annul temperature increases at high speed.Based on the latest 50 years air temperature of Huaibei region, a list of time-sequence is built. The list points out that the annual temperature of the latest 50 years is increasing at speed of 0.2℃/10a, and the spring temperature is increasing more fast at speed of 0.31℃/10a, for the winter is 0.45℃/10a.The autumn temperature is increasing at speed of 0.22℃/10a, and the summer...
