    Abstract:

    In order to evaluate the benefits of engineering measures for soil and water conservation in the black soil region,the novel large ridge,interval ridged-furrow(3°,5°),ridge and furrow subsoiling,change ridge,terrace field,field bund,grassland and forest were selected as experimental plots,and two conventional cultivation,longitudinal ridge(3°,5°),were selected as control treatment in project areas of"integrated control of erosion in black soil region of comprehensive agricultural development" in the Hailun City,Heilongjiang Province.Soil and water conservation were monitored during the rainy season from June to September in 2011.The results indicated that the engineering measures for soil and water conservation were superior to cultivation measures,and large ridge closing planting was the most benefit measures for soil and water conservation among all the measures of cultivation.The benefits for soil and water conversation under eight land use types were different,as grassland>forest>navel large ridge>change ridge>terrace field>field bund>3°interval ridged-furrow>5°interval ridge-furrow.Measures such as novel larger ridge,interval ridge-furrow and ridge and furrow subsoiling had the obvious timeliness.
