352 37 ADVANCES IN MODELING AND APPLICATIONS OF SOIL SOLUTE TRANSPORT LI Bao-guo HU Ke-lin HUANG Yuan-fang LIU Gang ( College of Resources and Environmental Sciences, China Agricultural University, Beijing 100094 ) Abstract The research on the soil solute transport has been a fundamental and cutting-edge field in soil and water sciences, ecology and other relevant disciplines in association with resources and environmental studies. The paper systematically discussed the research advances in modeling for soil solute transport given by multiple scales as well as its applications in agricultural production, resource management and environmental protection. The paper finally provided an outlook for its development trend in future. Key words Soil, Solute transport, Model, Applications, Multiple scales
