湖泊潜流带水交换研究现状与思考

Research status and consideration of water exchange in lake subsurface current zone

湖泊是湿地系统的重要组成部分,在维持当地水源、调节局部气候、保护生物多样性和生态环境等方面具有不可替代的地位。作为湖泊湿地系统的重要组成部分,湖水和地下水在以往的研究中常被视作独立的子系统分别调查,这极可能造成水资源评价的较大误差,导致水资源调配不合理、利用不充分。本文基于对湖泊潜流带水交换的研究现状的分析,梳理总结了定量研究该水交换过程的不同研究方法,主要包括直接测量法、水量平衡法、水动力学法、温度示踪法、水化学/同位素法、数值模拟法等;综合叙述了研究方法的发展动态,并对湖泊潜流带水交换研究进行了思考和展望。

As an important part of wetland system,lakes play an irreplaceable role in maintaining local water sources,regulating local climate,and protecting biodiversity and ecological environment. As an important part of lakewetland system,lake water and groundwater are often regarded as independent subsystems to be investigated separately in previous studies,which is likely to cause large errors in water resource evaluation,resulting in unreasonable allocation and inadequate utilization of water resources. Based on the analysis of the current research status of water exchange in the lake subsurface current zone,different research methods for quantitative study of the water exchange process are summarized,including direct measurement method,water balance method,hydrodynamic method,temperature tracer method,hydrochemistry/isotope method,numerical simulation method,etc. In this paper,the development trend of research methods is summarized,and the research on water exchange in lake subsurface current zone is considered and prospected.
