| 中文摘要: |
| 利用内蒙古农牧交错区13个站点20a的土壤水分观测资料和常规气象资料,分析了前期不同时段降水量(R)和参考作物蒸散量(Eo)与春季实测底墒的关系,分别建立了不同生态气候经济类型地区0～50cm和0～20cm土层的底墒估算模型,并利用2001～2002年土壤湿度和相应的气象资料对模型进行了检验,预测准确率平均为91.1%。 |
| 英文摘要: |
| The paper uses the soil moisture data and the conventional meteorological data measured by thirteen experiment stations or points in 20 years to analyze the relationships of rainfalls and evapo-transpirations during different periods with soil moisture in spring, thereby establishing the estimation models of soil moisture in 0~50 cm and 0~20 cm soil layers in the regions that belong to different economic and climatic types. Meanwhile, it also uses the soil moisture data and the meteorological data collected in 2001~2002 to test the models and shows that that have average estimation accuracy rate of 91.1%. |
