ET0是国际通用的评价水资源和计算作物需水量的基础数据，也是制定水法及国际河流水资源分配的重要依据。准确地确定ET0值对指导节水灌溉、发展农业节水有着十分重要的现实意义。笔者通过对地表温度数据的分析，运用遥感技术对青海省东部农业区ET0进行单站和区域分析，获取青海省东部农业区面上的ET0值及其分布规律。绘出ET0与LST的相关关系图，发现在只有单因素的情况下，有些站的ET0和LST的相关关系不大，而有些站ET0与LST的相关关系显著。而在分析其综合因素的情况下，ET0与LST的相关关系显著。

ET0 is the basic data of international general evaluation of water resources and calculation of crop water requirements and it is also an im-portant basis of making water law and allocating international river water resources. Determining ET0 accurately will have very important realistic meaning and profound influence on guiding the development of water-saving irrigation. The purpose of this study is through LST data's analysis,u-sing remote sensing technology and its method to analyze single station and regional of the agricultural regional of ET0 . It will get the ET0 value and its distribution rule on agriculture of eastern part of Qinghai Province.
