【Abstract】 Limited rainwater in arid regions is accumulated in soil for crop growth with ridge and furrow rainwater harvesting system(RFRHS),which increases production obviously and has gradually developed into the main water-saving irrigation technology in arid regions in China.This paper briefly introduces the principle of rainwater harvesting,application effect of RFRHS,some classical rainwater harvesting models and agricultural ecosystem models.The three influence factors and the proposals are put forward based on the current research progress,and the future development direction is prospected,which aims to provide theoretical and technical guidance for RFRHS development in arid regions in China.更多还原
