中文摘要：

利用GEWEX-SRB数据对新疆地区1984-2007年的辐照度进行分析,得到新疆地区近24 a的太阳辐射时空变化趋势.研究表明,该地区辐照度在空间上从东南部向西北部逐渐减小,从春季到冬季,辐照度逐步由经向分布向纬向分布转变.季节平均值夏季最大,春秋次之,冬季最小.年变化呈单峰趋势,接近正态分布,最大值出现在6月份.日变化表现为14时最大,17时、11时、20时、8时依次减小.24 a整体呈现增大趋势,但增大缓慢,夏季变化呈减小趋势,其余各季节均呈增大趋势.

英文摘要：

The spatial and temporal distribution of about 24 years＇ solar radiation in Xinjiang area was obtained by analyzing 1984-2007 solar radiation in Xinjiang area based on GEWEX-SRB data. The results show that the spatial distribution of solar radiation reduces from southeast to northwest gradually, the spatial distribution of solar radiation changes gradually from warp direction distribution to latitude direction distribution from spring to winter. The season average of solar radiation is the highest in summer, followed annually variation shows single peak trend, close to the normal by autumn and spring, and the lowest in winter. The distribution with the maximum value appearing in June. The daily mean solar radiation is the highest at 14：00, and then reduces in turn by 17：00, 11：00, 20：00 and 08：00. The average value of solar radiation flux for 24 a rises gradually and slowly. The change trend decreases in summer and increases in the rest seasons.
