| 摘 要： | 陆面蒸散是陆面水分平衡的主要分量,也是地球系统水分消耗的主要途径,但陆面蒸散量测量技术一直没有得到很好地解决.利用LOPEX试验区内陇中黄土高原定西陆面过程综合观测站的历史观测资料,在参考对照蒸发皿观测的水面蒸发量的基础上,对蒸渗计法、涡动相关法、彭曼方法等3种方法观测的陆面蒸散量的年变化特征进行了比较分析,发现各观测... |

| Abstract: | Evapotranspiration process is the principal componet of hydrological budget on land surface and is the main form of earth system′s water consumption.However,the land surface evapotranspiration on the measurement and estimation problem has never been a very good solution.In this paper,by using the historical observation data from DIXI land surface′s comprehensive observation station in LOPEX experimental area,the annual variation and integral total amount of the land surface evapotranspiration of lysimeter,eddy correlation method,Penman method,and evaporation pan observation of four methods are compared and analyzed to find that different observational methods in measurement of evapotranspiration have quite different results.The annual variation and seasonal variation of the ratio of eddy correlation method and lysimeter、the ratio of Penman and pan,as well as the ratio of Penman method and lysimeter method are studied.At the same time,the ralation of the ratio of the different methods and local micro-meteorological characteristics are discussed. |
