摘　　要：由于人类活动影响日益加剧,过去几十年我国水域空间发生了显著变化,全面掌握水域空间的分布格局及其演变规律,对于规划管理国土空间和水域岸线、促进生态系统健康稳定发展具有重要意义。基于30 m空间分辨率的土地利用数据,提取得到1980年、1990年、2000年、2010年和2018年我国水域空间分布情况,从面积和结构两个维度对其演变规律进行解析;基于全国十大水资源一级区水域空间演变的基本特征,将全国分为六大区域,针对不同分区存在的突出问题提出相应保护对策建议,为水域空间的保护修复提供参考。Due to the impact of intensified human activities in China, dramatic changes have taken place in space of water bodies for the past few decades. Understanding the law and pattern of distribution and evolution is of great significance for land space and shoreline planning and management, as well as health and stability of ecosystem. Based on the data of land use with 30 m spatial resolution, the spatial distribution patterns of space of water bodies in 1980,1990, 2000, 2010 and 2018 are collected. Its evolution law has been analyzed from two dimensions of area and structure. Based on basic features of evolution in the top ten grade-I water resources areas of China, six regions are divided with relevant measures and suggestions, which may provide insight for the protection and restoration of space of water bodies.
