摘要：

本文分析了由于人口增多,耕地面积减少,土壤严重退化及不协调的种养业结构使得四川粮食安全形势日趋严峻的基本情况,并阐述了粮草间套作的重要意义。通过分析认为，实行粮草间套作,能显著控制水土流失、改良土壤质地、提高土壤肥力，能够提高单位面积农业产出、增加农民收入，因此粮草间套作是适于四川丘陵区持续发展的种植模式。

Abstract:

This paper reviewed the population growing, farmland decreasing, serious soil degradation and inconsistent structure between breeding and planting, indicates that the food security tendency in Sichuan province was getting worse. Based on the reviewed results, the conclusions were: crop and forage intercropping could control soil erosion, improve soil texture and fertility, increase farmers' income and agricultural output of unit area. Therefore, the crop rotation of forage intercropping with crop was the sustainable crop rotation of hilly area of Sichuan province.
