气候变化情景下的地下水潜在补给变化影响分析--以栾城试验站为例
The effects of climate change on potential groundwater recharge-A case study of Luancheng experimental station
摘要
Abstract
Understanding the effects of climate change on potential groundwater recharge is considerably vital for the scientific management and evaluation of groundwater resources.This study combined the climate generator (ClimGen) with groundwater recharge model (Visual HELP) to assess the potential groundwater recharge rate under 3 assumed future climate scenarios (10% decrease in precipitation (P),2 ℃ increase in temperature (T),and both occurring simultaneously (P&T)) in Luancheng ecological experimental station.The results indicated that the future (2011-2040) multi-year mean recharge rates in these three scenarios would decrease by 23.33%,4.42%,and 26.01% respectively compared to the baseline (in 1961-1990).The reduction in precipitation had an especially significant effect on groundwater infiltration recharge.This study has important significance in guiding the management and sustainable exploitation of groundwater resources.关键词
