Research On The Tourism Climate Comfortable Degree Of Major Cities In The Loess Plateau Region

This paper is based on the study of the tourism climate comfort at home and abroad, choose the loess plateau area as the research object, according to the average temperature in the 20 cities in the past 30 years,such as the average humidity, average wind speed, sunshine time of the month value data.Then through temperature humidity index, wind cold index, dressing index, comprehensive climate comfort index of major cities tourism climate comfort evaluation analy the temporal variation characteristics and optimum of tourism and dividedinto climatic regionalization. In the end several tourist activities related to climate comfort on this are analyzed.In this paper,the main research results are as following:1.For many years the distribution of major cities’temperature of years is inverted U shape.Follow from January to July basically shows ascendant trend, from July to December, basically shows a downward trend.The distribution of major cities’ an average relative humidity of the year is peak and valley type distribution for many years. From April to September, the average relative humidity is on the rise, in April after September the year average relative humidity is the obvious downward trend.In general on the loess plateau region average temperature has obvious descending trend from southeast to northwest. For many years major cities’the average wind speed distribution is basically unimodal.From.January to may, the wind speed is on the rise.then falling to around November wind speed is on the rise again.For many years in all major cities the average sunshine numerical time is obviously different, but its basic trend is consistent. the sunshine time is abundant in this area, the sunshine hours were greater than 2000 hours.2. If we choose more comfortable and comfortable as a basis for selection of suitable tour of the city, for major cities in Loess Plateau area, then from December to January are not suitable for tourism; Apart from Wuqiaoling,all cities is suitable for tourism inApril and May. There are mang cities is is suitable for tourism, the choice is flexible.3. The spatial distribution characteristics of the main urban tourism climate comfort degree in the Loess Plateau:the central area is the most comfortable month. The tourism climate comfort degree of spatial difference is small, but the seasonal tourism climate comfortable degree of spatial difference is large, spring, summer, autumn three quarters of the comprehensive climate comfortable degree index to higher than winter comprehensive climate comfortable degree index. In the spring and autumn of the two seasons, the trend of climate comfort index change is basically the same, with the increase of the dimension, the comprehensive climate comfort index is declining. In summer and spring and autumn, the overall climate comfort index change trend is just the opposite, with the rise of the dimension, the overall climate comfort index is rising.4. The climate regionalization of 20 cities in the Loess Plateau is divided into two types:the type of summer and autumn.In the Loess Plateau, the climate of summer is the most typical type of tourism climate.,It is basically distributed in the northern and western regions of the region. Comprehensive climate comfortable degree developed a"U" type structure, comfort index is the highest in summer, spring and autumn, winter comfort index is the lowest. The most typical features of this type of tourism climate types are as follows:spring and autumn fitness is cold in winter and hot in summer, Only the spring and autumn season tourism climate comfort index is the highest, Change of comfortable degree in city comprehensive climate of this type was "M" type structure, comfort index in spring and autumn comfort index was the highest,But in summer and winter is lowest.5. Summer doline in loess plateau area development is mainly concentrated in the northwest and north of this area. Optimum in developing ice-snow tourism in this area is suitable from December to February next year. The best development of the recreational type of tourism comfort from May to September.The best suitable for the development of forest recreation type tourism comfort from May to September. The forest recreational tourism can be carried out in May and September. In the southern minority city because of high temperature and moisture from June to August, It is not suitable for developing forest tourism.
