Estimation Study on Agriculture Water Requirement in Irrigation Area for Careful Regulation of Water Resources of the Yellow River
The four irrigation areas, Ningxia, Inn-Mongolia, Henan and Shandong Provinces (municipality), are the main agriculture farmland for fine regulation of water resources of the Yellow River. It is important to establish water requirement evaluation model for predicting agriculture water requirement in the irrigation areas during water dispatching in the Yellow River. Water requirement analysis during growth of paddy and drought-crop was given in this paper and main effecting factors were discussed for water demand of irrigation area. An evaluation model was proposed integrating with calculation of crop water requirement, soil surface water content and soil moisture distribution on vertical aspect for synthetically considering the factors of account weather, crop and land hydrology course, irrigation requirement and soil moisture status to predict water requirement in the irrigation areas under different weather condition and different irrigated flux. Furthermore, water regulation of the Yellow River can be calculated and simulated combining with the analysis of weather condition and crop water requirement of irrigated area in the future. This paper will provide a method for calculating irrigation requirement for water regulation of the Yellow River based on remote sensing monitoring technology.
