新疆主要棉区光合有效辐射、光温生产潜力的估算、分析

Analysis and Evalution of PAR(Photosynthetically Active Radiation)and Light－ Temperature Productivity Potential

利用新疆 8个气象站近 30年的总辐射、直接辐射、散射辐射和日照时数的资料，分析了公式 Qp=aQ中比例系数 a的变化特征，按月给出了全疆光合有效辐射的计算公式，计算了主要棉区的光合有效辐射；并结合 6个气象站的温度资料估算了新疆主要棉区棉花的光温生产潜力。

： On the basis of the data of total radiation,direct radiation,scattering radiation and sunshine time from 8 meteorological stations in Xinjiang over thirty years,the feature of coefficient a is evaluated in Qp=aQ.The formula of PAR is given in every month in Xinjiang and PAR of main cotton area is also analyzed.With the help of temperature data from 6 meteorological stations,the productivity potential is evaluated in main cotton area in Xinjiang.
