| 摘 要： | 基于蒸发的物理机制,分析晋西黄土残塬区影响坡面蒸发的主导因子,提出了可以在不饱和土壤水分情况下应用的坡面土壤蒸发模型。认为坡度、坡向、土壤含水量、最高气温及植被盖度是影响坡面蒸发的主导因子。该模型对精确定量黄土残塬区小流域的生态需水及指导小流域水土保持生态环境建设具有重要意义。

| Abstract: | Based on the physical mechanism of evaportranspiration, this paper analyzed main factors affecting slope e-vaportranspiration in loess gully area of Western Shanxi province; put forward evaportranspiration models of slope soil in the condition of unsaturated soil moisture. It is shown that the slope gradient, aspect, soil moisture, maximum temperature , vegetation coverage are the major factors affecting slope evaportranspiration. The models may be used well in precise computing ecological water requirement and guiding of soil and water conservation in small watershed. |
