摘  要：
根据塔里木灌区-阿拉尔垦区1961—2010年逐日地面气象要素值,采用Penman-Monteith模型、距平相关和回归分析方法比较分析了近50年塔里木灌区-阿拉尔垦区ET0与E变化特征、影响因素和相关关系。结果表明,1近50年塔里木灌区-阿拉尔垦区年E高于年ET0,温暖季节(4、5、6、7、8、9月)E高于ET0,寒冷季节(12、1、2、3月)E低于ET0,ET0最大值出现时间、转折时间均滞后于E。2塔里木灌区-阿拉尔垦区ET0和E变化是由多种气象因子共同作用的结果,年、秋季ET0和E变化受温度影响较小,冬季受温度影响较大。3塔里木灌区-阿拉尔垦区冬季ET0和E线性关系明显(p<0.01),可采用E值估算ET0;年、春、夏、秋季ET0和E线性关系不明显。

摘  要：
Based on the daily meteorological data from 1961 to 2010in Alar of Tarim irrigation area,the changing characteristics,influencing factors,correlation relationship between reference crop evapotranspiration(ET0)and pan evaporation(E)in recent 50 years in Alar of Tarim irrigation area were analyzed.The results showed that:1The annual pan evaporation was higher than ET0 in recent 50 years,and the pan evaporation was higher than ET0 in the warmer season,which contained April,May,June,July,August,September and October.And the pan evaporation was lower than ET0 in the colder season,which contained December,January,February and March.And the presentation time and turn time of maximum ET0 lagged far behind pan evaporation.2The changes of ET0 and pan evaporation were controlled by variety of meteorology factors in common,and pan evaporation and ET0 were not influenced relatively by temperature in annual and fall,but were influenced relatively in winter in Alar of Tarim irrigation area.3The linear correlation between ET0 and pan evaporation was highly significant(p<0.01),and pan evaporation could be used to estimate reference ET0 in winter;But the linear correlation between ET0 and pan evaporation was not significant in annual,spring,summer and autumn.
