博斯腾湖生态输水对地下水的影响研究
|
摘要
为进一步研究博斯藤湖生态输水对周围地下水及其植物生长发育的影响,文章基于Visual MODFLOW模型和实测资料构建了博斯腾湖地下水流数值模型,并重点分析了生态输水期间地下水的动态变化规律。结果显示:河流入渗、地表水入渗以及降水入渗为博斯腾湖生态区地下水补给的主要来源,并且降水入渗补给受气象条件的影响较为显著;在输水面积不断扩大而输水总量不变的条件下,地下水入渗量呈增大趋势并达到1.65×104m3/d,补水效果十分显著,生态恢复区地下水位在入渗补给作用下不断提升,并最终趋于稳定。对地下水均衡影响最为显著的因素为气象水文条件,其中地下水的排泄、径流和补给过程在一定程度上可受到生态补水活动的影响作用。本研究可为博斯腾湖补水方案的优化及生态修复提供一定参考和决策依据。
ter area enlarged constantly and total amount of water conveyance unchanged, the groundwater infiltration is in increasing tend and reaches 1.65×104m3/d,the effect of water recharge is very significant,and the groundwater level in the ecological restoration area has been rising constantly affected by infiltration recharge,and gradually keeps a constant level. The most significant factor affecting groundwater balance is meteorological and hydrological conditions,in which the discharge,runoff and recharge process of groundwater can be affected by ecological recharge activities to a certain extent. This study can provide reference and decision-making basis for optimization of water recharge scheme and ecological restoration of Bosten Lake.
