摘　　要：为建立新型的节水型灌区,科学用水、计划用水,利用山西省中心试验站蒸渗仪,进行了长达10年的试验研究,充分利用马氏瓶调控地下水浅埋区的水位动态变化,得出了最佳地下水埋深范围,建立了动态模拟的作物生育期内潜水蒸发模型。本模型适用于6种地下水埋深情况,可对相似或相近水文地质条件的灌区提供参考依据,为指导当地农业生产和灌区调控地下水埋深提供科学的依据。This paper researches phreatic evaporation rule being influenced by different groundwater table, climatic factor and crop growing, and builds dynamic phreatic evaporation model during crop growing period, which will provide theoretical foundation for new irrigation district, scientific water use, planned water use. With special equipments of Central Equipment Station in Shanxi province, this model was established on basis of the results of the optimal groundwater level range which was measured by taking full advantage of high sci-tech way to regulate groundwater table change after more than ten years＇ research. The model could be applied to the situation of 6 kinds of groundwater level, and provides reference to other irrigation districts which are under the condition of similar hydrological geology. The results are widely used to direct local agricultural production and achieve better benefits of society and ecology, and would give scientific foundation of sustainable development for agriculture and water conservancy.
