| 摘 要： | 研究参考作物腾发量的时空变化特征,有助于了解新疆维吾尔自治区农牧业及生态需水的分布与演变规律。选择新疆吾尔自治区范围68个气象站的气象观测资料,应用Penman-Monteith公式,计算得出不同气候分区的历年参照作物腾发量ET0,分析了不同气候分区不同年份ET0的变化情况。采用ArcGIS空间插值技术绘制新疆维吾尔自治区参考作物腾发量的分布图,结果表明:各站ET0变化在660~1 800mm,其空间分布总体表现为南疆大于北疆、东部大于西部、盆地大于山区的分布格局。

Temporal and Spatial Variability of Reference Evapotranspiration in Xinj iang |

| Abstract: | The research of the temporal and spatial characteristics of reference evapotranspiration is helpful to understand the distribu-tion and variability of the agricultural and ecological water requirement.Based on the daily meteorological data of than 68 stations all over Xinjiang,every year reference evapotranspiration was estimated by using the Penman-Monteith equation.Analyzed the different climate partitions different years the change of ET0 .The spatial distribution of ET0 was obtained by GIS and method was used for spatial interpolation.The results show that All stations ET0 variation in 660~1 800 mm,the spatial distribution of overall perform-ance for the southern Xinj iang is greater than the northern Xinj iang,the east is greater than the west,the distribution pattern of ba-sin is greater than the mountains. |
