Abstract

Based on meteorological data in the past 53 years (1966-2018), this paper analyzes the climate comfort changes in Qinhuangdao by using the method of climate comfort evaluation and trend analysis. The results show that the climate comfort changes in the northern mountainous area of Qinhuangdao, the central plain and the southeastern coastal areas are consistent, and there are spatial differences. In general, Qinhuangdao's climate comfort is mainly comfortable to cool, the comfort and relative comfort levels of each region account for 47% to 49%, and the cold discomfort level accounts for 34% to 37%,the hot and hotter discomfort levels are rare. In the past 53 years, the climate comfort in summer and winter shows a warming trend, and the warming range in winter was larger than that in summer. In the past 53 years, the number of hot uncomfortable days has increased sharply since the 1990s, and the number of cold uncomfortable days has decreased year by year. The number of hot uncomfortable days increases with the decrease of altitude and latitude of the station in space, while the number of cold uncomfortable days is the opposite. The climate is comfortable or relatively comfortable from May to October. The whole area of Qinhuangdao is suitable for tourism and recuperation from May to October. There is no intense hot in July and August. The “slightly hot” weather provides favorable weather conditions for people to swim in the sea, the relative cold climate in March, April and November is a good time for outdoor mountain climbing, the climate is cold and uncomfortable from December to February, not suitable for mass tourism, but suitable for ice and snow tourism activities. Therefore, it can be considered that Qinhuangdao is suitable for tourism all seasons. This provides a basis for tourism development and planning in Qinhuangdao and for studying the impact of climate change on tourism, and provides life and travel weather service guidance for the Kangyang group that came to "Qinhuangshanhai, Kangyangfudi".
