The climate an important part of human survival environment and natural resources, it isclosely linked with the survival of mankind and social activities. In recent years, globalwarming, high temperature, extremely cold and heavy rain extreme weather events occurfrequently, and cause of the meteorological elements mutations, directly or indirectly, to thehuman life, production and human health a significant impact. In China’s coastal areas hasbeen considered a human settlement environment is one of the best climate comfort area. Inthe background of the global climate change, how to actively respond to climate change andconstruct a comfortable living climate environment has become a hot topic in the geographiccircles research area. Therefore, comment the city residential environment climate comfort,not only help building a comfortable living climate environment, but giving some suggestionfor the responding of global climate change.Take Liaoning coastal cities as an example. First of all, reviewed the domestic andforeign relevant research of climate change and habitat environment, and introduces thepurpose, content and related theory basis. On the basis of analyze the natural, social andeconomic conditions change of Liaoning coastal cities in recent years, select the climate datafrom1951to2010, using the method of anomaly, climate tend to rate, five-year movingaverage and Mann-Kendall test to analyze the basic climate change characteristics The resultsshowed: temperature changes grow a warming trend by the rate of0.311℃/10a, which isconsistent with global temperature change characteristics; Precipitation, wind speed andrelative humidity was a downward trend, tendency were-12.795mm/10a,-0.193m/s/10a,-0.678%/10a; The meteorological elements in the period1960-1980had evident mutations. Inthis climate context, carried out in Liaoning coastal urban climate comfort evaluation bycalculating human comfort index. The results showed that the living climate comfort inLiaoning coastal cities is good over the past60years, the BCMI showed a clear upward trendduring1951to2010, which is consistent with global warming. Most people feel comfortablefrom April to October, and the most comfortable months are from June to September.Predict the future climate comfort development trend in Liaoning coastal cities by themethod of R/S analysis. It was found that the Hurst values of elements were greater than0.5,indicating that in the future temperature will continue to raise, precipitation, wind speed andrelative humidity to maintain the current decreasing trend, the BCMI in Liaoning costal will increase The correlation analysis found that the temperature and wind speed are the mostimportant factors of climate comfort. According to interaction among urban development,climate change and habitat climate comfort, we should respond to the global climate changeactively and reduce the impact of human activities on climate.
