基于Landsat8影像的策勒县域典型时期日蒸散量时空分布格局分析
Analysis of Temporal and Spatial Distribution Pattern of Daily Evapotranspiration in Qira County Based on Landsat 8 Images
摘要
Abstract
[Objective] The estimation of surface evapotranspiration is beneficial to the rational allocation and management of water resources,which might provide the basis for the sustainable development of water resources.[Method] By using the Landsat 8 remote sensing data set,With the support of the ENVI remote sensing image processing software,combined with the air temperature,air pressure,wind speed,sunshine duration and other meteorological data,evapotranspiration was estimated by SEBS model in March 27th,May 21st,July 24th and September 10th 2016 in Xinjiang Qira County.[Result] The results could reflect season change;for instance,the results of farmland were 3.885,4.095,4.701,4.511 mm/day on four days respectively.The overall trend was the northern desert plain ＜ the southern mountains ＞ the central region.[Conclusion]The results of SEBS estimation are compared with those calculated by Penman formula,which shows that the results of SBES model are reasonable.关键词
