This is the information obtained by the reporter at today's "Liupanshui, Du Liang, China" demonstration achievement conference. \ x0d \ x0d \ Liupanshui average altitude 1750m, annual average temperature 13℃- 14℃.

The average temperature in July, August and September with the highest temperature is 19.8℃, and the historical extreme maximum temperature is only 3 1.2℃. According to the domestic prevailing human comfort standards, the climate data of Liupanshui city center 197 1 to 2000 are analyzed in detail. The results show that people feel cool and comfortable in Liupanshui city for more than 96% of the time. According to the relevant personnel of Liupanshui Meteorological Bureau, Liupanshui is located at the intersection of water vapor circulation in the Bay of Bengal, cold air circulation in Siberia and subtropical high circulation in the Pacific Ocean, with abundant rain and suitable temperature. Although it is located in the plateau above 1800 meters above sea level, the ultraviolet radiation is weakened by the atmospheric clouds with a thickness of 1000 meters and a humidity of 70%, which makes the ultraviolet radiation milder. \ x0d \ x0d \ At present, Liupanshui can receive 3,000 to 4,000 tourists at the same time, but the level is not high. In order to improve the reception level, Liupanshui is going to develop hotel construction in the middle and high-end direction, and strive to build three four-star hotels in about three years and five-star hotels in five years. In terms of highways, there are 20 kilometers long and 40 meters wide Zhongshan Road, Duliang Avenue and Renmin Road being rebuilt, and Wumeng Avenue to be built soon.
