萍乡市2018~2024年地下水动态变化分析

Analysis of Groundwater Dynamics Change in Pingxiang City (2018~2024)

摘要: 萍乡市作为全国首批海绵城市建设试点之一，其地下水系统对城市生态调节与雨洪管理具有重要影响。本文描述性统计分析了2018~2024年萍乡市6个水利部门国家级地下水监测站实测水位资料。结果表明，全市地下水水位基本稳定，且年均水位呈上升趋势；地下水主要补给来源为降水入渗，受地下水类型影响，不同区域水位对降水的响应存在滞后性差异；地下水总体空间分布规律为安源区、湘东区水位较低，其余三县水位较高。研究结果可为萍乡市进一步加强地下水资源的合理开发和监管保护，保障地下水可持续利用提供数据支撑。

Abstract: Pingxiang City, as one of the first pilot sponge cities in China, has a groundwater system that plays a significant role in urban ecological regulation and stormwater management. This study descriptively and statistically analyzes observed water level data from six national groundwater monitoring stations managed by water conservancy departments in Pingxiang City from 2018 to 2024. The results indicate that the groundwater levels in the city remained generally stable, with an overall rising trend in the annual average water level. The primary recharge source of groundwater is precipitation infiltration. Depending on the groundwater type, different regions exhibit varying lag times in water level response to precipitation. Spatially, groundwater levels are relatively lower in Anyuan District and Xiangdong District, while higher levels are observed in the other three counties. The findings provide data support for Pingxiang City to further strengthen the rational development, regulatory protection, and sustainable utilization of groundwater resources.
