摘　　要：【研究目的】地下水资源评价对地下水资源可持续利用管理和生态环境保护具有重要意义,地下水资源区划分是地下水资源评价的基础和关键。【研究方法】本文依托松辽流域水文地质调查工程,以水循环和地下水系统理论为指导,根据地下水的补给、径流、排泄特征和储存特征,采用水文地质特征与地表水流域相结合的方法,将松辽流域地下水资源区进行了重新划分。【研究结果】松辽流域由整体到局部,共划分为4个级别,其中一级区2个,二级区6个,三级区17个,四级区56个。一级区以地表水一级流域划分为松花江和辽河流域;二级区以大型平原(盆地)为中心,包含周边山区补给区进行划分,以此形成完整的地下水补径排系统;三级区将分别划分平原(盆地)和其周边山区补给区;四级区将山区按地表水四级流域划分,松嫩平原和辽河平原按地表水二级流域进行划分,三江平原和海拉尔盆地保持独立分区不再细分。【结论】松辽流域地下水资源区新划分方案,有效兼顾了地表水流域和地下水系统,完整地反映了地下水形成演化过程,是地下水系统理论的成功应用,为新一轮地下水资源评价提供了科学依据。This paper is the result of hydrogeological survey engineering.[Objective]Evaluation of groundwater resources is essential for the management and sustainable utilization groundwater resources as well as the preservation of the ecological environment.The groundwater resources division serves as the foundation for assessing groundwater resources.[Methods]Based on the groundwater survey engineering,the theory of water cycle and groundwater system and the features of recharge,runoff,discharge and storage,the groundwater resources area of the Songliao River Basin is redivided by combining hydrogeological characteristics with surface water basins.[Results]There are four division levels:2 first-level subareas,6 second-level subareas,17 third-level subareas,and 56 fourth-level subareas.The first-level subarea is divided into the Songhua River Basin and Liaohe River Basin based on the first-level drainage basin of surface water.The secondary zone is centered on a broad plain(basin)and includes nearby mountain recharge zones in order to create a unified groundwater recharge and drainage system.The plains(basins)and surrounding mountain recharge areas are separated in the tertiary division.The fourth level zones in mountainous regions are divided by the fourth surface water basins,the Songnen Plain and Liaohe Plain are divided by the secondary surface water basins,and the Sanjiang Plain and Hailaer Basin remain independent and undivided.[Conclusions]The division scheme of new groundwater resources area in the Songliao River Basin effectively takes into account the basin and groundwater system,and completely reflects the formation and evolution process of groundwater.It is an effective application of groundwater system theory that provides a scientific premise for the next round of groundwater resources evaluation.
