摘要
地表蒸散是水量平衡和地表能量平衡的主要组成部分,目前已经发展多种估算地表蒸散量的方法,对比分析各种蒸散估算方法,遥感方法被认为是目前估算蒸散的最佳方法.通过总结遥感方法估算地表蒸散研究进展,对比遥感估算蒸散常用的3种方法:统计经验法、数值方法和理论方法,介绍常用遥感估算地表蒸散模型,并简要探讨遥感方法估算地表蒸散存在的问题.
Land surface evapotranspiration (LSE)is the main component of water balance and land surface energy balance,and which has developed a variety of land surface evapotranspiration estimation methods at present.Contrasting analysis of various evapotranspiration estimation methods,remote sensing method is considered as the best method to estimating land surface evapotranspiration currently.Through summarized the research progress of land surface evapotranspiration estimation methods based on the remote sensing t...
