摘要: 根据1994年4月~10月青藏高原太阳分光辐射的实测资料,计算出太阳总辐射中,光合有效辐射(PAR)所占比例η=0.439±0.009,PAR每1J的能量含有4.43μmol的量子。在青藏高原的气候学计算中,可用下式估算旬平均的PAR能量日总量HPAR(MJ·m-2d-1)和量子日总量UPAR(mol·m-2d-1):HPAR=(0.399+0.036lgE*)·H UPAR=(1.768+0.159lgE*)·H式中H(MJ·m-2d-1)为总辐射旬平均日总量,E*=E·P0/P,P0(hpa)为标准大气压,P(hpa)为测点大气压,E(hpa)为地面水汽压。

Abstract: Based on the measured data of spectral radiation on Qinghai Xizang Plateau from April to October, 1994, ratio of photosynthetically active radiation ( PAR ) to global radiation was presented, i.e. η =0.439±0.009, and 1J energy of PAR is equivalent to 4.43 μmol quantum. In the climatological estimation of Qinghai Xizang Plateau, following equations can be used to estimate the averages for every ten days of daily total PAR energy HPAR(MJ·m-2d-1)and daily total quantum UPAR(mol·m-2d-1):HPAR=(0.399+0.036lgE*)·H UPAR=(1.768+0.159lgE*)·H H(MJ·m-2d-1) is the average daily global radiation for ten days. E*=E·P0/P,P0(hpa) is the standard atmospheric pressure, P (hpa) is the atmospheric pressure at the spot, E (hpa) is the water vapor pressure on the ground.

Key words: Qinghai Xizang Plateau, photosynthetically active quantum value, climatological estimation
