The paper examines the characteristics of runoff yield and erosion and sediment yield of sloped land in earth-rock low mountainous area in the west of Liaoning through setting runoff plots of natural slope, analyzing observation datas of runoff and silt from the plots and establishing mathematical model by taking 7 kind of land use types of Erdaoling small watershed in Erdaoling village, Guohua township of Fuxin county in the west of Liaoning as a research object. The research shows that there is better correlation between the amount of runoff and sediment, showing logarithmic relationship; the sequence of soil conservation of different soil and water conservation measures is as follows: leveled pit (95.16%) > leveled terraced (87.11%) > ridge plant zone (83.99%) > horizontal ridge cultivation (40.23%) > ecological rehabilitation (29.07%) > vertical ridge cultivation (18.22%). 5°～15° sloped land in the earth-rock low mountainous area in the west of Liaoning should use leveled pit and leveled terraced as the main measures and the mountainous area where has less population, more land and poor natural conditions should take ecological rehabilitation as the main.%以辽西地区阜新县国华乡二道岭村的二道岭小流域7种土地利用类型为研究对象,通过布设自然坡面径流小区、分析小区径流泥沙观测数据、建立数学模型,探索了辽西土石质低山区坡地产流与侵蚀产沙的特征.研究表明:径流量与侵蚀量有着较好的相关性,二者呈对数函数关系;各种水保措施保土率的排序为水平坑(95.16%)＞水平梯田(87.11%)＞地埂植物带(83.99%)＞横垄耕作(40.23%)＞生态修复(29.07%)＞顺垄耕作(18.22%).辽西土石质低山丘陵区5°～15°的坡耕地应以修筑水平坑和水平梯田为主,人少地多、自然条件差的山区应以生态修复为主.
