摘　　要：本文依据土城子小流域水土流失情况,科学选定水土保持设计参数,对荒坡治理工程(截水沟)、坡式梯田、地埂植物带等关键工程给定设计参数,并针对经果林造林,合理选择坡式梯田整地或穴状整地模式,还依据保土耕作条件,确定耕作方案。经分析,设计措施生效后,直接经济效益每年可增加281.75万元。In the paper, soil and water conservation design parameters are selected scientifically according to soil and water loss condition of small watersheds in Tuchengzi. Design parameters are given in key projects such as waste slope treatment project （water drainage ditches）, slope terrace, ridge plant belt, etc. Slope terrace land preparation and cavernous land preparation modes are rationally selected aiming at economic fruit forestation. Cultivation plans are determined according to soil conservation cultivation conditions. After the design measures take effect, direct economic benefits can be increased by 2. 8175 million Yuan each year according to analysis.
