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。 Inner Mongolia obo small watershed belonged to the loess Bingling area, the characteristics of soil moisture in this area are: uniform soil texture and lighter texture, strong soil water holding capacity, more effective water content, deeper soil water storage, soil into the miserable ability Strong. The soil moisture content has obvious differences due to tillage measures, land use status, aspect and its location, thus affecting the productivity of the soil. It can effectively absorb rainfall by adopting measures such as constructing hilly land and terraced fields, intensive cultivation and loose surface soil Miserable, improve farmland water conditions and crop moisture conditions.
