The Analysis Of Climate Comfort In Western Liaoning Province

Habitat environmental assessment includes many aspects,and the most basic and important one is climatic factor.Climate change has led to the changes in the living environment,and it further affects the degree of comfort to the living environment.In recent years,the global climate is changing,and the main manifestation is rising temperatures.At the same time,the development of urbanization in China is rapid,which damaged the original ecological environment,and changed the local town's climate and affected the degree of comfort to the living environment.With the continuous progress of science and technology and the social improvement of living standards,people are increasingly concerned about the comfort of the living environment.Analyzing the climate comfort living environment can be analyzing of the impact of climate changein some degree,and the more important is that could help to provide suggestions for the construction of "livable city".Usingthe daily data of meteorological elementsin 1960-2014 from western Liaoning district eight meteorological offices and stations such as average temperature,wind speed,relative humidity and sunshine time and so on,and analyzing the main meteorological elements affecting the climate comfort,we describe the basic characteristics of each factor,and test the Mann-Kendall mutation;Using national standard residential environment comfort model to calculate the western Liaoning region climate comfort,and analyzingthe characteristics of various levels stay time and space distribution;Using Geographical probe method to detect the meteorological factors that affects the climate comfort,and analyzing the contribution amount of various meteorological elements to the climate environment comfort;Using the method of clustering analysis to analyze the spatial difference of western Liaoning region climate comfort.The conclusion is as follows:(1)Western Liaoning region almost 55 years meteorological data analysis shows below:From time perspective,almost 55 years western Liaoning a significant rise in the average temperature and average relative humidity,the temperature change was inverted u-shaped curve monthly,the average relative humidity is higherin summer,but lower in spring and winter;Average wind speed changes significantly monthly,the maximum speed is in April,the minimum is in August;The longest average sunshine time is in the spring,and the shortest is in winter.From Space perspective,the average temperatureand the average relative humidity in the coastal area are higher than inland,the average wind speed in western mountains is lower than the eastern plains,and sunshine time is decreasing from west to east.(2)Western Liaoning region different grades have significant different climate comfortable days in time and space.Level 1(very cold,uncomfortable)days are more,the most are 226 days in Zhangwu;but level 3(Comfortable)days are in about one-third of a year,and the most are 121 days in Jianping;Level 2(slants cold,less comfortable)and level 4(thermal,less comfortable)days are relatively less,and level 5(Sultry uncomfortable,uncomfortable)days rarely appear.As the change of climate,level 1 days gradually reduce,but level 3 days increase gradually,which means the western Liaoning region climate environment gets comfortable.According to the number of comfortable days in the western Liaoning region,we divided into three categories,respectively dry a comfort zone,cold and comfort zone and warm wet comfort zone.(3)The change of the climate comfort degree is the outcome of combined action of various meteorological elements,among them the most significant influence is temperature,which contributes more to the winter or summer.Winter half year was mainly affected by temperature,wind speed and sunshine,and summer half year was affected more by temperature and relative humidity.
