    摘要:

    本文从研究耕作措施出发,提出了地表平坦或地表起伏不平时二维土壤蒸发过程的数值分析方法。作为应用举例,分析了沟种垄作对苗床土壤水分与温度分布的影响,并作了田间试验验证。这一研究为农业生态学提供了一种定量分析方法。

    Abstract:

    Soil moisture and temperature of the seed zone in dry land farming are mainly affected by the surface evaporation and the structure of seedbed . A two-dimensional numerical model of evaporation from the surface of flat or undulated heterogeneous soil was developed and validated by field experiment for the purpose of optimizing tillage operations.When the surface is flat, the different evaporation rate from each surface element can be ccalculated using finite element method based on one-dimensional evaporati...
