据研究秦岭火地塘林场的气候要素中，太阳的直接辐射、总辐射、净辐射和风速均随海拔高度的升高而增大，其中直接辐射和总辐射随海拔高度的升高按指数规律增大。散射辐射、地面有效辐射、气温、水汽压、降水量和蒸发力随海拔高度的升高而减小．其中散射辐射和水汽压是随海拔高度的升高按指数规律减小。地面有效辐射和降水量随海拔高度的升高呈抛物型变化，即最初随海拔高度的升高而增大，到一定高度后转为随高度的升高而减小。最大有效辐射出现的海拔高度为２５００ｍ，最大降水量出现的海拔高度为２０００ｍ（相对高度１２００ｍ）。
According to the study of the climate elements of the Huoditang Forest Farm in Qinling, the direct radiation, total radiation, net radiation and wind speed of the sun all increased with the altitude increasing, and the direct radiation and total radiation increased exponentially with altitude Increase. Scattering radiation, effective radiation from the ground, temperature, vapor pressure, precipitation and evapotranspiration decrease with altitude. The scattering radiation and vapor pressure decrease with exponential law as the altitude increases. The effective radiation and precipitation in the ground presented a parabolic change with altitude, which initially increased with the elevation above sea level, but decreased to a certain altitude and then decreased with altitude. The maximum effective radiation appears at an altitude of 2500m and the maximum precipitation appears at an altitude of 2000m (relative height 1200m).
