通辽地区水资源系统输入、输出信息的确定

DEFINITION ABOUT INPUT AND OUTPUT INFORMATION OF WATER RESOURCE SYSTEM IN TONG LIAO AREA

本文基于动态发展的观点 ,确立了通辽地区水资源系统有限元模拟模型中各单元逐时段系统输入输出信息的计算模型 ,诸如降雨入渗补给量、潜水蒸发量、河渠和水库引放水渠渗漏量、地下水净开采量及灌溉回归水量等信息都综合考虑了降雨量大小、潜水蒸发强度、河渠流量大小、开采量 (或灌溉量 )大小和地下水埋深的关系 ,还考虑了其随时间、空间位置的变化关系。

In this paper a computer model of system input and output at each element and time interval of ground water resource system in Tong Liao area is established in terms of dynamic development. Precipitation ,evaporation of phreatic water, water extraction (or irrigation water use ), relationship between canal flow rate and ground water depth and their variation in space and time are all considered in the information such as replenishment of precipitation infiltration, evaporation of phreatic water, irrigation return (or deep percolation ), canal percolation.
