摘要
基于2024年广州市地下水动态监测数据,对地下水水位动态特征及其主要影响因素进行了分析。结果表明:广州市地下水年均水位埋深为3.65 m,空间上呈现北部丘陵区埋深较大、南部滨海平原区埋深较小的分布规律;年内动态与降水量高度相关,呈现“雨季快速响应—旱季缓慢下降”的特征。研究共识别出3种典型地下水动态类型(渗入—蒸发型、气象—人工型、渗入—径流型)及其主控因素。该研究揭示了广州市地下水水位动态变化规律,为区域地下水资源管理与保护提供了科学依据。
Based on the 2024 Guangzhou groundwater dynamic monitoring data,the dynamic characteristics of groundwater level and its main influencing factors were analyzed.The results show that the annual average depth of groundwater in Guangzhou is 3.65m,with a spatial distribution pattern of higher depth in the northern hilly areas and shallower depth in the southern coastal plain areas;The temporal dynamics of water level within a year are highly correlated with rainfall,exhibiting a characteristic of"rapid response during the rainy seasons and slow decline during the dry seasons".Further research has identified three typical types of groundwater dynamics(infiltration evaporation types,meteorological artificial types and infiltration runoff types)and their main controlling factors.This study reveals the dynamic changes in groundwater levels in Guangzhou,providing a scientific basis for regional groundwater resource management and protection.
