摘要
Abstract
A field rainfall simulation experiment was carried out to seek a way of reducing soil and water loss in sloped lands .The effects of slope ,soil bulk density and residue cover on runoff yield and sediment yield were also studied . The results showed that the effect of slope on sediment yield was greatest in the 3 factors .Runoff yield and Sediment yield increased with slope increasing within 15° .The rainfall infiltration could be effectively increased ,but the total sediment yield increased with the decrease of bulk density .When soil bulk density was 1.2 g・cm - 3 ,runoff reduced markedly with a little sediment yield increase .Residue cover could effectively decrease runoff yield and sediment yield , and the effect of sediment yield was more significant .Slope should choose small slope .Soil bulk density should choose 1.2 g・cm - 3 when slope less than 10° .Slope land should choose no‐tillage when slope more than 10° .We should in‐crease the straw mulching .But the straw mulching rate should not exceed 80% .关键词
