Based on the meteorological data in China in the last 50 years (including the complete data for Xiong'an New Area since 1974), this paper studies and analyzes the climate change and the climate ecological characteristics in China, especially, in Xiong'an in recent decades. Xiong'an is in the zone of the warm temperate semi-humid monsoon climate, with a climate background similar to that of Beijing and Tianjin. In recent decades, temperature, precipitation and other meteorological elements take an obvious change trend but with a weak amplitude, the annual average temperature is increased by 0.2℃ per decade, and the number of hot days is increased by 0.8 days per decade, the number of heavy rain days shows a trend of decrease, the change ranges of elements are all lower than those in China as a whole and in the surrounding cities, as the results of the effects of climate change on Xiong'an. The number of extreme weather events is also increased, such as the heavy rainfall return period is shortened, the number of extreme strong rainfalls is increased obviously and so on. This is as shown in the IPCC's report, and the trend in most regions in China. Based on the analysis of the disaster historical data and the climate model prediction, it is pointed out that under the background of the global warming, Xiong'an will face increasing meteorological disasters and climate risks caused by the climate change in its development, and some suggestions are made.
