Sustaining environmental flows (e-flows) is a basic requirement for river, lake and marsh management. Rivers, lakes and marshes have close hydrological and ecological connections in a river basin, and form river–lake-marsh systems. Any measure that is designed to address problems related to only one of these water bodies in isolation of the others may lead to unexpected, undesired and sub-optimal consequences for one or all of the water bodies. Papers were selected for this special issue ‘Environmental Flow Mechanism and Management for River-Lake-Marsh Systems’ to illustrate recent advances in revealing new mechanisms connecting hydrological and environmental/ecological processes, developing new methods for e-flow calculation, and establishing new measures for e-flow management.

河湖沼泽系统环境流动机制与管理

维持环境流量（电子流量）是河流、湖泊和沼泽管理的基本要求。河流、湖泊和沼泽在流域内具有密切的水文生态联系，形成河流-湖泊-沼泽系统。任何旨在解决仅与这些水体中的一个相关的问题而与其他水体相关的任何措施都可能导致对一个或所有水体产生意想不到的、不希望的和次优的后果。本期特刊“河流-湖泊-沼泽系统的环境流量机制和管理”入选论文，以说明在揭示连接水文和环境/生态过程的新机制、开发电子流量计算新方法以及制定新措施方面的最新进展用于电子流管理。
