摘要
"四水"是指大气水、地表水、土壤水和地下水,农灌区"四水"转化的定量关系是制定农业灌溉计划和调控田间土壤水及地下水的基础。根据淮北平原各项实验参数指标建立了农灌区"四水"转化模型,提出该模型在农田径流预报、土壤水消退及地下水位模拟等方面的应用,并提出该模型的作用和推广前景。
＂Four kinds of water＂ refer to atmosphere water,surface water,soil water and groundwater.The quantitative analysis of four kinds of water＇s transformation in agricultural irrigation is the basis of developing agricultural irrigation plans and controlling soil water and groundwater.This paper establishes the hydrological model of the four kinds of water＇s transformation based on the experimental parameters indicator of the Huaibei Plain,puts forward the application of this model in farmland runoff forecasting,soil water retreat and underground water level simulation and finally describes the function and popularization prospect of this transformation model.
