Use of Remote Sensing to Assess the Water-Saving Effect of Winter Wheat Fallow
Winter wheat fallow policy has a greater effect on water resource management, and the water-saving effect in the fallow process of winter wheat can provide data support for precise water resource utilization planning. In order to evaluate the water resource consumption of winter wheat and the relate...
