摘要
鄱阳湖是长江流域的典型通江湖泊,也是我国面积最大的浅水湖泊和国际重要湿地。2003年来,受长江与鄱阳湖之间"江湖关系"变化影响,加之流域区域人类活动干扰,鄱阳湖湿地退化特征明显。以习近平总书记关于"长江大保护"的重要论述为根本遵循,综述国内外研究文献并统计分析相关数据,梳理了鄱阳湖湿地保护研究的关键问题及研究思路。从确立恢复和保护目标、揭示湿地演替驱动机制,构建系统恢复和保护体系等方面提出未来需关注的关键科学问题;从宏观与微观结合、过程与格局结合、结构与功能结合、热点与空缺结合等角度提出关键科学问题的研究思路,以期为鄱阳湖湿地保护提供科学参考。
Lake Poyang is a typical river-connecting lake in the Yangtze River basin,the largest shallow lake in China,and an internationally important wetland providing habitats for a large number of rare spe⁃cies.Since 2003,Lake Poyang has been showing obvious degradation characteristics due to the combina⁃tion of"river-lake relationship"between the Yangtze River and Lake Poyang,and the severe disturbance of human activities at the watershed and regional scale.Following the spirit of General Secretary Xi Jin⁃ping's series of speeches on"the Great Protection of the Yangtze River",related references were reviewed and data statistical analysis was conducted to reveal key questions and research thinking for protection of Lake Poyang wetland.This paper focuses on three key questions such as the status of wetlands,the driv⁃ing mechanism of wetland succession considering the“river-lake”relationship,and how to construct a sys⁃tematic restoration and protection system.In this paper,four key mechanisms were finally proposed,such as making a close connection between the ecological indicators at macro-scale and micro-scale,between ecological process and landscape pattern,between ecological structure and function,between hot spots and vacancies,in order to provide reference for effective scientific research on river-connecting wetlands.
