【Abstract】 This paper focuses discussion on the mutual transformation relationship amongst metcoric water, surface water, soil water and groundwater in farmlands under different water-supply conditions with the exsitcnce of crops. It stresses the difference between precipitation permeation and phreatic-water evaporation with the exsitence and the absence of crops as well as the significance of soil water in the agricultural ecosystem. The research makes an exploration to the multipurpose developmcnt of water resources.更多还原
