Based on the snow data of seven weather stations of Chengde and the meteorological data of Weichang Weather Station from 1951 to 2011, the climate suitability, sustainability, and climate risk for the construction of a ski resort in Weichang are analyzed and evaluated through studying of the inter annual variation characteristics of meteorological factors such as snow, temperature, wind, precipitation, and weather disasters (including fog, dust, thunderstorms, and hail). The results show that Weichang is the best place to build the ski field in Chengde, where there exists snow cover mostly from November to the following March (the best time for skiing is November and December), and there are more than 20 comfortable days from June to August, which is suitable to carry out other tourism projects in the ski resort. The possibility of avalanche is very low in Weichang, but severe weather occurs frequently in off season of skiing, so the early warning and defense measures of 〖JP2〗weather disasters should be taken during this time. In order to ensure the sustainable development of the ski resort, it is recommended that the construction scale of the ski resort cannot be too large and the numbers of ski activities should be limited strictly.
