摘　　要：随着我国人口增长和人均资源的逐年减少,我们已直接面临到非常严峻的土壤、水和肥料资源问题,商品粮生产基地的东北地区出现了水分亏缺、养分亏缺等日益严重的问题。针对这些问题,我国自"八五"以来,把"旱地农田水肥交互作用及耦合模式研究"作为攻关重点专题,通过国内外的研究现状对未来的水肥耦合的研究趋势作出了宏观的分析。We have faced directly to the extremely stem question such as soil, water and fertilizer resources along with the growing of population in our country and reduce of the per capita of natural resources year by year. As a commodity grain base, northeast area appear some serious issue that water deficit and nutrient deficit and so on day by day. In view of these questions, our country take research on interaction between water and fertilizer and coupling model in arid farmland as a key topic, and has made the macroscopic analysis to the development trend of water and fertilizer and coupling in the future through the development of domestic and foreign.
