粤西及相邻地区太阳总辐射、光合有效辐射能量和光量子通量时空分布

应用普适全国的计算太阳辐射、光合有效辐射和光量子通量模型，系统地研究了粤西的高要、封开和临近地区梧州的太阳辐射、光合有效辐射和光量子通量的年总量、月总量以及相应的年平均日总量和日平均日总量。结果表明，太阳辐射、光合有效辐射和光量子通量的年变化有相似的规律；而地区变化有以下特点：梧州和封开明显类似，而高要与上两地差异稍大。

The Temporal and Spatial Distribution of Solar Radiation,Photosynthetically Active Radiation and Quantum Flux in Western Guangdong and Its Adjacent Area

Based on the collection of related weather records ,we adopted a non-linear regressionmodel for solar radiation,photosynthetically active radiation(PAR) and quantum flux,to cacu-late the annual solar radiation totals,the annual mean daily solar radiation totals,the monthlysolar radiation totals,the monthly mean daily solar radiation totals,the annual PAR totals,themonthly mean daily PAR total,and the correspoliding quantum flux totals in relation to the vari-ous PAR totals in Weastern Guangdong and adjacent arca.The annual changes of solar radiationtotals,the PAR totals and the quantum flux totals are similar.All of them are increased graduallyfrom January to July,then decreased from August to December,Geosraphically,fluctuations ofchanges of solar radiation totals,PAR totals and quantum flux total in Wuzhou District andFunkai County are slighty smaller than that in Gaoyao Gounty.
