摘要
内蒙古敖包小流域属于黄土兵陵区，该区土壤水分性质特点是：剖面土质均一且质地较轻，土壤持水能力较强，有效水含量较多，土壤深层贮水较丰富，土壤入惨能力强。土壤墒情因耕作措施、土地利用状况、坡向及其位置不同产生明显的差异，进而影响土壤生产力，采用修筑水平埝地和梯田，精耕细作，疏松表层土壤等措施，能有效地接纳降水就地入惨，改善农田水分状况和作物水分条件。
Aobao watershed in Inner Mongolia falls into the loessal hilly regionswhere sill water is characterized by uniform distribution but light texture in soil profile,more available water contents,richful water storage in deep layers abd better soil waterinfiltration ability,There is an obvious difference in soil moisture status caused by differ-ent cultivation measures,land use,directions and locations of slopes,thus,further affec-tiong soil productivity.A ccordingly,such measures as constructing level terrace lands,practising intensive farming and loosening upper soil layers to be adopted can hold rain-fall water and make it penetrate into soil effectively,which can improve water regime infarmlands and crop water conditions.
