人工回灌对地下水年龄分布规律的影响
Effect of artificial recharge on groundwater age distribution
摘要
Abstract
Groundwater renewable capacity is a key indicator of the sustainability of groundwater development,and renewable capacity can be expressed quantitatively by groundwater age.Under the influence of human activities,the actual status of groundwater is quite different from that under natural conditions.Based on the status of underground reservoir construction and artificial recharge in the Tailan River Basin,the influence of infiltration basin location,recharge intensity and thickness of the unsaturated zone on the distribution of groundwater age is examined with the physical experiment and numerical simulation.The results show that the artificial recharge has reduced the regional mean groundwater age.The change of infiltration basin location and recharge intensity has a significant effect on the distribution of groundwater age.Increase of the thickness of the unsaturated zone increases the residence time of the recharge water and the mean age of the groundwater.This study can provide technical guidance for rational evaluation of the regional groundwater renewability capacity.关键词
