| 摘要: |
| 在2年初步试验的基础上，通过对山西寿阳县年雨量、气温与蒸散量的分析，建立了保护性耕作土壤水分模型及其相关子模型。用此模型能预测特定地区作物各生长阶段的土壤含水量、任意年的降水量、任一天的平均气温和年蒸散量与径流量。试验验证结果表明，此模型能较好地反映各种耕作处理下土壤水分的变化情况。 |

| Abstract: |
| On the base of two year,s experiments,through analysis of annual precipitation, temperature and evapotranspiration of Shouyang, Shanxi province, a main soil moisture model and submedels are developed. For a specific district,this model can simulate soil water content in any stage,annual precipitation,average temperature of a day,annual evapotranspiration and runoff. Verification with experiments shows that this model can be used to express the variation rules of soil water content,soil temperature,evapotranspiration, runoff and water loss for the fields with conservation tillage (inShouyang and similar districts). |
