鄱阳湖湿地景观破碎化过程与恢复对策研究

Study on the Fragmentation Process and Restoration Countermeasures of Wetland Landscape of the Poyang Lake

鄱阳湖湿地是我国重要的自然资源,具有较强的生态作用,但近年来鄱阳湖湿地的保护现状却不容乐观。本文利用地理信息基础理论和遥感技术手段,基于2013年和2017年的遥感影像图对鄱阳湖湿地景观的面积、结构及时间变化进行研究,进而探索鄱阳湖湿地景观的破碎化过程。结果表明,鄱阳湖湿地的景观类型以建筑用地、水田和裸地为主,该区域主要受到人为因素和自然因素影响,导致湿地景观破碎化程度较高。为对湿地进行恢复,本文基于研究结果和现实情况提出了加强重点保护区建设、进行自然封育、进行适当退耕还湖、加强管理监督、重点突破与全面治理相结合和运动科技手段保护湿地等措施。

Poyang Lake wetland is an important natural resource in China and has a strong ecological role.However,the protection status of Poyang Lake wetland in recent years is not optimistic.This paper uses the basic theory of geographic information and remote sensing technology to study the area,structure and time change of Poyang Lake wetland landscape based on the remote sensing image maps of 2013 and 2017,and then explore the fragmentation process of Poyang Lake wetland landscape.The results show that the landscape types of Poyang Lake wetland are mainly construction land,paddy field and bare land.The area is mainly affected by human factors and natural factors,resulting in a high degree of fragmentation of wetland landscape.In order to restore the wetland,based on the research results and the actual situation,this paper proposes to strengthen the construction of key protected areas,carry out natural enclosure,carry out appropriate returning farmland to the lake,strengthen management supervision,combine key breakthroughs with comprehensive governance,and exercise scientific and technological means to protect wetlands.Measures.
