| 摘 要： | 利用四子王旗气象站1959—2010年月平均气象资料,在较长时间尺度上分析了植物生长季节(5—9月)月平均气温、降水量和日照百分率的变异度,以及降水与温度、降水与日照百分率之间的关系,评估了降水是否是影响温度和日照的主要因素。结果表明:①5月和9月降水量较少,日照百分率大,气温低;月降水量和平均气温的变异度较大,日照百分率的变异度相对较小;而7、8月降水较多、气温较高,气温和降水变异度都较小。②5月和9月温度受降水以外因子影响较大,其与降水的相关性较差;6—8月,温度与降水呈显著的负相关关系,降水量多则气温低,影响效果明显。③除6月外,各月降水量与日照百分率负相关关系显著,线性拟合效果优于气温,日照百分率随降水量的增加明显降低。盛夏,受夏季风影响,该地水汽条件好,云层厚且不易消散,导致光照少,是日照百分率较低的主要原因。

| Abstract: | Based on the month mean data from 1959 to 2010 of Siziwang Banner weather observing station,the variation of mean temperature,mean precipitation and percentage of sunshine during the growing season（May to September） on a relatively long temporal scale were analyzed,If the precipitation was major factor that influencing temperature and sunshine was estimated.The results showed that the precipitation was lesser in May and September,but high in percentage of sunshine,the temperature was low,and the variability of precipitation and temperature were large,but the variability of sunshine percentage was small,July and August have high temperature and large precipitation,but the variability of them are small.Temperature of May and September was mainly affected by the factors other than precipitation,and did not relate to precipitation well,in June to August,temperature shows an obvious negative correlativity to rainfall,and the more was the rainfall,the low was the temperature.Except June,percentage of sunshine showed a more obvious negative correlativity to precipitation in every month than temperature.As the rainfall increased,the sunshine percentage decreased sharply.In summer,influenced by the monsoon,this area had so much steam that the clouds were dense and not dissipate easily,which may be the reason of the low percentage of sunshine. |
