Study on ET management concept-based integrated technical system of water resources management in Yellow River Basin

Based on the new concept of ET for water resources management,an integrated technical system of water resources management in the Yellow River Basin combined with ET management concept is established from the regional water balance equation on the basis of the deep analysis and discussion made on the shortcomings that need to be complemented and improved from the current surface water management system;which includes a surface water resources management system,an ET management system and a ground water resources management system,and then some problems to be resolved for establishing and improving the ET management system and some feasible approaches to solve them are discussed and proposed herein as well.
