Abstract:It is studied that,among the climatic element at Huoditang forest farm in Qinling moun-tain range,increase of direct solar radiation ,gross solar radiation,net radiation and wind speed areaccompanied by the progressive going up of elevation,and direct solar radiation and gross radiatlonincrease with elevation by the law of exponential function。 However, scattered radiation,ground ef-fective radiation,temperature,moisture pressure precipitation and evaporation capacity are goingdown with the increase of altitude。Scattered radiation and moisture Pressure decrease exponentiallywith the elevation going up,while ground effective radiation and precipilaion vary parabolically withthe elevation,which means when elevatton goes up both elements increase at the begining,but turnto decrease in a certain elevation later.The elevation is 2500 m when the maxium effective radiationappears,2 000 m when the maxium precipitation emerges.
