| 摘 要： | 根据对研究区多年的水文地质观测资料的分析和研究,建立了黑河中游典型灌区地下水水资源总均衡模型,选取了黑河干流具有代表性的平川、板桥、鸭暖和蓼泉灌区,对地下水均衡模型中的补给项及排泄项的主要变量分别进行了估算,结果表明:各灌区均衡期内地下水动态资料计算的均衡期始末地下水储存量变化与模型计算的均衡差基本相近,其相对误差为-17.6%,说明均衡模型对于估算内陆绿洲灌区地下水资源均衡是比较准确的。

| Abstract: | Based on the long-term hydrologic observations in study area,the model of the estimation of groundwater budget at the representative irrigation area in the middle reaches of the Heihe River was established in this paper.The recharge terms of groundwater in the model include: runoff,precipitation and condensation recharge to phreatic water,recharge from deliver and distribution canals,irrigation water infiltration and reservoir leakage;the discharge terms of groundwater include: effluent stream in the region,phreatic evaporation and groundwater mining.They were calculated respectively in the irrigated districts,such as Pingchuan,Banqiao,Yanuan and Liaoquan.Results from this model indicate that the difference between the volume of groundwater in storage at the beginning and at the end of groundwater budget period was equal to the volume difference calculate with the model,and the relative error between observed and calculated differences of groundwater budget is-17.6%,indicating that this model is valid in calculating the groundwater budget in oasis irrigation districts. |
