The gradient observation data of microclimate measurement in a shorter period were analysed.The results are as follows:(1) The total solar radiation,net radiation,reflected global radiation,PAR and UV radiation have diurnal variation with high and low values,and the highest values have appeared at 14:00.All radiation have the same trends.The radio of net radiation,PAR,UV radiation to total solar radiation are 58%,20%,36%,and 14%,respectively.(2) The variation of heat flux in soil is lower,the variation in daytime is higher than that in the night.At the time from 07:00 to 17:00,the thermal energy is transferred from soil surface to deeper soil,and it is transferred from deeper soil to surface soil at the other times.The variations of G,H and λE is relative stable,they are about 20%,38%,42%,respectively.(3) In Haibei alpine meadow regions at Qilian mountain,the soil-air temperature varied very extremely in horizontal and vertical directions at the exact range;but at the another levels,the variation is relative stable.The inversion layer of atmosphere usually occured from 20:00 to next day 11:00.(4) The wind velocity has a stronger diurnal variation and short-term change.At the vertical direction,the wind velocity has an obvious time distribution.
