| 摘 要： | Agro-chemical transport processes at different scales are discussed and relevant opening question are identified by literature review to make some suggestions concerning the improvement of research methods for filed scale solute transport by aid of evaluation of existing models,and examining transport behaviors of solute in vadose zones on different scales.The results indicate that present research progess and understanding on field scale solute transport have not yet been enough to guarantee the use of our models for the management of field soulte movement.Much more research work needs to be done,particularly,in aspects of high resolution of spatial structures relevant to the hydraulic and transport properties,explicit numerical simulation of actual structure on field scale and field measurement corroborated with model development.
