陕西省旅游气候舒适度评价

Evaluation of Tourism Climate Comfortableness in Shaanxi Province

气候舒适的程度及持续时间的长短，是影响旅游地旅游季节长短的重要因素。本文利用陕西省30年气候资料，采用温湿指数、风寒指数和着衣指数指标，对陕西省各地区各月旅游气候舒适度进行了分析。结果显示，陕北各地区旅游舒适期在5月～9月，关中各地区的旅游舒适期多在4月、5月、9月和10月，汉中和安康舒适期在4月、5月、9月和10月，商洛的旅游舒适期在4月、5月、6月、8月和9月，不舒适期以榆林最长为4个月，以汉中和安康最短为O个月。由于地理位置和海拔高度的不同，陕西省内各个地区的旅游气候舒适度有相当的差异，在南北方向上差异尤其明显。冬季南北差异性表现尤为突出，舒适指数随纬度的升高而降低。全省可以分为陕南、关中、陕北、秦岭4个旅游气候区。

The comfortable degree of climate is very important to the development of tourism and it is also a major factor which affect duration of tOUrism season. Based on 30-year climatic data in Shaanxi Province, the climate comfortable degree of each month in Shaanxi Province is analyzed by the way of the THI, WCI, ICL as well as the comprehensive comfort index. The three comfort indexes are quantified in order to calculate them, and we stipulate that the climate is comfortable when Z （the sum of THI, WCI, ICL） ≥ 6, the climate is fairly comfortable when 3 〈 Z 〈 6, the climate is relatively uncomfortable when 0 〈 Z ≤ 3, the climate is uncomfortable when Z ≤ 0. The results show that, in Northern part of Shaanxi, the climate is comfortable from May to September, and climate in January, February and December is uncomfortable. In Guanzhong area, the climate in April, May, September and October is comfortable, and climate in January, February is uncomfortable. Climate in April, May, September and October is comfortable in Hanzhong and Ankang, there is no uncomfortable climate in Hanzhong and Ankang. In Shangluo, climate in April, May, August and September is comfortable, and uncomfortable in January.The comfortable climate in Yulin, Yanan, Tongchuan, Xianyang and Shangluo lasts for five months, which is the longest in Shaanxi. The comfortable climate in Huayin lasts for a very short time, only three months. The uncomfortable climate in Yulin lasts for four months, which is the longest in Shaanxi. There is no uncomfortable climate in Hanzhong and Ankang. In winter the climate is uncomfortable in most areas in Shaanxi, besides Yulin, Yanan, Tongchuan and Shangluo. The climate in spring and autumn is the most comfortable in a year. The differences of geographical location and the sea level lead to the different comfortable index of each area in Shaanxi Province, especially obvious in the direction of North to South in winter. The annual sum of the index of Ankang is the highest, and the annual sum of the index of Yulin is the lowest. Climate comfortable degree is decreasing as the latitude rising. The best places for tourism in July and August are Yulin and Tongchuan. In the cold December and January, your wise choice for tour is Hanzhong and Ankang. Shaanxi can be divided into four parts, such as the Southern, Guanzhong, Northern and Qinling based on Climate comfortable degree. This provides a scientific theory for planning the development of tourism in Shaanxi province and a reference for tourists to decide where and when they should have a trip.
