| 摘要: |
| 本文对土壤水分模拟方法进行了探讨,并通过对土壤—植被—大气生态系统的动态分析,建立了土壤水分的系统动态模拟模型。该模型仅需常规气象资料,即可模拟计算逐旬土壤水分均值。通对对比实测可模拟的结果,表明两者在变化趋势上有明显的一致性,模型可基本反映土壤水分的变化规律。 |

| Abstract: |
| The simulating method of soil moisture is discussed in this paper. After systematic analysis of water balance in soil-plant-atmosphere eco- system(SPAS),a dynamic model for simula(?)ing ten-day average soil moisture is proposed.The model is composed of three equations:infiltr- ation rate,evapotranspiration rate and soil moisture state equation.The- re is also a drainage equation in addition.The model need only standard meteorological data and is casy to be run.It is demonstrated that the model simulates the... |
