Abstract
The purpose of this study is to make an attempt on establishing a method to assess water management for larger irrigated area using remote sensed information. Firstly, we analyzed the crop water consumption rule during the whole growing stage taking winter wheat as an example. Then the remote sensed assessment method of water use efficiency was established, which took remote sensed ET, biomass and observed precipitation as input data. Finally, the method was applied for the assessment of irrigation water use efficiency in Beijing Tongzhou district over the three growing seasons of 2003-2004, 2004-2005, 2005-2006 of winter wheat. In the end, the feasibility of this method is validated by comparison the results with year-to-year variation of statistical yields. The assessing results can be used for water managers and policy makers in improving irrigation water use efficiency.
