| 摘 要： | 针对干旱地区平原绿洲水土资源利用的特点,建立了以农区土壤水为中心的干旱区平原绿洲散耗型水文模型。散耗型模型考虑了水在不同介质和不同形态之间的交换或转化,并重点考虑人类活动如引水灌溉、地下水的开采等对水平衡的影响。模型把研究区划分为河段、泉井、水库湖泊、农区和非农区五类水均衡模块,水均衡模块之间通过地表渠系、地下水侧渗进行水量交换。应用模型可以对研究区农区、非农区各自的蒸发量、农区向非农区地下水迁移量等干旱区主要水分散耗项进行分析。

| Abstract: | According to the characteristics of the water and land resources utilization of arid plain oasis, a hydrological model based on agriculture area soil water movement is established. The water movement and exchange in deferent media and phases are investigated, and the influences of human activities such as irrigation, exploiting groundwater are also taken into consideration. The model divides the research area into five water balance modules: river module, spring-well module, reservoir-lake module, agriculture area module and non-agriculture area module, and the water exchanges between these modules are made through surface channel and groundwater movement. The model can analyze the main runoff-evaporation in an oasis such as the evaporation or evapotranspiration in agriculture area, non-agriculture area, and the groundwater transfer between agriculture area and non-agriculture area. |
