中文摘要	针对北方干旱地区坡耕地严重的水土流失问题,采取垄向区田、深松、横坡种植、免耕播种等水土保持耕作措施,于2010年,以黑龙江省齐齐哈尔市东兴村5°坡耕地径流场为研究对象,研究了不同耕作措施对地表径流、土壤侵蚀和降雨入渗的影响。结果表明,这几种水土保持耕作措施均有不同程度的减流减沙作用,其中横坡种植效果最为明显,地表径流量和土壤流失量较常规耕作分别减少了92%和90%,稳定入渗率较常规耕作提高了41.2%。不同耕作措施的径流系数过程线的变化、径流含沙率变化以及产流量、产沙量的变化均符合横坡免耕>横坡种植>深松+区田>垄向区田>少耕深松>免耕>常规耕作>裸地这一变化规律。
英文摘要	Different tillage measures of soil and water conservation,such as ridge tillage,subsoiling,cross-slope cultivation,and no-tillage seeding,are taken to control serious soil erosion on sloping farmland in the arid areas of Northern China.In 2010,the effects of different conservation tillage measures on surface runoff,soil erosion,and rainfall infiltration were studied on a 5° farmland in Dongxing Village,Qiqihar City,Heilongjiang Province.Results showed that all the conservation tillage measures had a certain effect on the reduction in runoff and soil erosion.Cross-slope tillage had the most obvious effect,with which surface runoff and soil erosion were reduced by 92% and 90%,respectively,and stable infiltration rate was increased by 41.2% as contrasted with conventional tillage.Changes in runoff coefficient,sediment concentration in runoff,runoff generation,and sediment yield under the different conservation tillage measures were all consistent with the order of cross-slope no-tillage > cross-slope cultivation > subsoiling and ridge tillage > ridge tillage > less tillage and subsoiling > no-tillage> conventional tillage > bare land.
