摘要: 使用1957-2013年艾比湖流域6个气象站点的平均大气压、平均气温、最高气温、最低气温、平均相对湿度、平均风速、日照百分率以及降水量资料,通过Penman-Monteith方程计算出各个站的月和年潜在蒸散量.利用线性倾向估计、累积距平法和Mann-Kendall法分析了该流域近57年的潜在蒸散量、气温及降水量变化特征.结果表明:近57年来艾比湖流域年潜在蒸散量以-25.05mm·(10a)-1的速度呈下降趋势.近7年的平均潜在蒸散量与过去50年相比较偏少77.36mm.年平均气温以0.33℃·(10a)-1的速度上升.近7年的平均气温比过去50年的平均气温增加了1℃.年降水量以7.97mm·(10a)-1的速度增多.近7年的平均降水量与过去50年的平均降水量相比增多32.45mm.

关键词: 艾比湖流域, Penman-Monteith方程, 潜在蒸散量, 气温, 降水量

Abstract: Meteorological data (average atmosphere pressure, average temperature, average maximum temperature, average minimum temperature, average relative humidity, average wind speed, percentage of sunshine and precipitation) from 1957-2013 were collected from six weather stations in Ebinur Lake basin. Monthly and annual potential evapotranspiration were calculated by Penman-Monteith model. The linear regression, cumulative anomaly and Mann-Kendall test were used to analyze the characteristics of potential evapotranspiration, temperature and precipitation changes. The results show that the annual average potential evapotranspiration had decreased with a rate of 25.05 mm·(10a)-1 during 1957-2013; the average potential evapotranspiration during the later seven years decreased 77.36 mm as compared with that in the former 50 years. Annual average temperature had increased with a rate of 0.33 ℃·(10a)-1 during 1957-2013; the average temperature during the later seven years increased 1.0 ℃ as compared with that in the former 50 years. Annual precipitation had increased too, with an increasing rate of 7.97 mm·(10a)-1, and average precipitation during the later seven years increased 32.45 mm as compared with that in the former 50 years.

Key words: Ebinur Lake basin, Penman-Monteith equation, potential evapotranspiration, air temperature, precipitation
