The Influence of Lanzhou Reach of Yellow River to Temperature-Humidity Effect on Surrounding Lawn and Brick Underlying Surface

The temperature and humidity on the lawn and brick underlying surface at differnet distances from the bank of Yellow River in Lanzhou, Gansu province, China (Lanzhou reach of Yellow River) were continuously monitored from 6 a.m. to 8 p.m. for 5 days in August and September 2013, respectively. With increasing distance, the temperature gradually increased, but the humidity remarkablely declined. The influence of Lanzhou reach of Yellow River on the temperature-humidity effect on the two underlying surfaces was dependent on the distance from the bank of Yellow River. The relationship between the temperature on the lawn or brick underlying surface and the distance was a significant positive correlation, but the humidity in this thesis and the distance showed the remarkable negative correlation relationship. The maximum distance of the temperature and humidity effect from the water of Lanzhou reach of Yellow River was calculated, and their range was 236.4-317.1 m and 248.8-289.2 m, respectively,
