　　Vegetation water content is one of the important biophysical features of vegetation health,and its remote estimation can be utilized to real-timely monitor vegetation water stress.Here,we compared the responses of canopy water content(CWC),leaf equivalent water thickness(EWT),and live fuel moisture content(LFMC)to different water treatments and their estimations by using spectral vegetation indices(VIs)based on water stress experiments for summer maize during three consecutive growing seasons 2013-2015 in North Plain China.
