摘　　要：以方塔流域为实例,讨论了退耕还林还草下的坝系及坝系农业发展问题,笔者认为淤地坝与退耕还林还草工程有机结合,构成了流域阻止泥沙出沟入黄的稳固屏障。建议在对流域生态经济问题调研的基础上,分析淤地坝建设及坝系农业发展的方向和规模。According to ecological and economic development of Fangta valley, the problems of dams construction and agricultural development of dams are discussed. The authors think the system of dams construction and the project of 'Converting Slope Cropland to Woodland and Grassland'is the steady barrier to preventing mud and sand from into Huanghe River,and suggest that the tendency of dams construction and agricultural development of dams are analysed in studying the ecological and economic problems of typical valley.
