山西宁武天池是我国珍贵的高山湖泊和地质历史遗迹。近年来,天池湖泊水量衰减日趋严重,水量衰减原因可归为自然因素与人类活动两类。水文分析计算表明:自然因素中降水量与蒸发量并非天池水量衰竭的主要因素,天池水量减少的主要原因是人类活动影响,造成天池底部隔水底板发生不同程度的裂隙,从而使天池水资源沿基岩裂隙下渗排出,并破坏区域地下水流动规律,导致地下水补给减少及渗漏量增大,进而造成天池储蓄水量减少和水面不断收缩。
Ningwu Tianchi in Shanxi Province is a precious mountain lake and geological history of China. In recent years, Tianchi lake water attenuation increasingly serious, water attenuation causes can be classified as natural factors and human activities in two categories. Hydrological analysis shows that precipitation and evaporation in natural factors are not the main factors of Tianchi’s water exhaustion. The main reason for the decrease of water in Tianchi is the human activities, resulting in different degrees of cracks in the bottom of Tianchi, so that the water resources along Tianchi Infiltration and infiltration of bedrock fissures and undermine the regularity of groundwater flow in the area, resulting in the reduction of groundwater recharge and the increase of seepage leakage, which in turn caused the reduction of water storage and water storage in Tianchi.
