基于"国家地理基础信息数据库"和《中国历史地图集—隋唐、北宋》为主信息源,生成隋唐(公元581-907年)和北宋(公元960-1127年)时期淮河流域湿地系统宏观格局分布图,结合淮河流域的相关历史地理文献,分析了隋唐和北宋时期淮河流域湿地系统的宏观格局变化,探讨了该历史时期淮水流域湿地系统的主要湿地类型的变化趋势、驱动与效应。研究表明:隋唐和北宋时,淮水流域湿地系统的宏观格局变化不大,隋唐时处在稳定阶段,北宋时处在较稳定阶段。河流和湖沼等自然湿地宏观分布格局变化小,是当时流域湿地系统保持宏观格局稳定的基本原因。流域湿地系统变化主要来自于以运渠、库塘和灌溉沟渠等为主的人工湿地的发展和演变,隋唐王朝的宏观政策促进了当时流域各类人工湿地的发展;唐末—北宋熙宁元年,流域各类人工湿地因战争等政治原因大量荒废;北宋中期后因系列新政实施,流域人工湿地又得以再次发展。隋唐—北宋时淮河流域人工湿地的变化与历代王朝的政治、经济和文化的发展存在一定程度上的关联影响。
