摘　　要：郑州地下水均衡试验场的改建,是中国地质环境监测院主持的国家地下水监测工程中地下水均衡试验场的改建项目之一,由河南省地质环境监测院具体负责实施。针对场地尺度均衡试验资料推广至野外生产实践核心问题,采用确定型模型(水分运移方程)和随机模型(区域性包气带参数)相结合的研究方法。拟选黄河南冲洪积区24 km^2作为野外试验场地,通过场地上有限数量的采样,标定该场地包气带参数变异性特征,并借助于区域气象资料,结合地下水均衡试验场所建土壤水分运移数学模型成果,计算区域降雨入渗补给量与潜水蒸发,为地下水资源评价、地质环境评价及地下水资源可持续开发利用提供科学依据。同时也为大范围土壤面状污染评价工作奠定基础。The reconstruction project of groundwater balance experiment site of Zhenzhou was rebuilded by Geo-environmental Monitoring Institute of Henan Province, belongs to one of the national groundwater monitoring projects,which is performed by China of Institute Geol-Environment Monitoring. In view of the key application problems of extending site-scale equilibrium test data to field production practice,this paper considers the combination of deterministic model( water transport equation) and stochastic model( regional vadose zone parameters). It is proposed to select 24 km^2 of the alluvial-producing area of the South Yellow River as a field test site to carry out regional variability study of the parameters of the vadose zone. Through limited sampling in the site,the parameter variability characteristics of vadose zone at any point in the site can be calibrated. With the help of regional meteorological data and the result of the established soil water transport mathematical model in the groundwater balance test site,the infiltration recharge of precipitation and the evaporation of phreatic water in the site are calculated,which can provide scientific basis for groundwater resource evaluation,geological environment assessment and groundwater resource sustainable development and utilization. Meanwhile,also lays a foundation for large-scale soil surface pollution assessment.
