摘要 湿地的生态环境退化和可持续发展问题已成为当前湿地研究的焦点问题,有必要及时开展湿地动态变化监测研究。通过3期遥感影像解译,获得了海南东寨港湿地类型空间分布数据,并在此基础上分析了2002年、2008年和2013年东寨港保护区湿地类型及其动态变化。结果表明: 近12 a来海南岛东寨港湿地类型变化不大,滨海海域、红树林和养殖塘是保护区主要湿地类型; 保护区自然湿地面积呈下降趋势,但湿地总面积和斑块数量均呈增加趋势,其中潮沟面积增加比例最大,养殖塘斑块数增加显著; 保护区斑块数量和面积变化较大的地方多发生在陆地边缘,这也是人类活动较为频繁的区域。2002—2013年间,保护区各湿地类型变化动态度不大,其中滨海海域、潮沟和红树林湿地类型变化缓慢,是保护区内稳定少动的湿地类型,而水库、沙质潮间湿地及坑塘类型变化迅速,具有相对较大的动态度,是保护区湿地类型变化的快速变动类型。

Abstract:Ecological environment degradation and sustainable development of wetland has become the focus of the current wetland research, it is necessary to study on wetlands monitoring dynamic changes.The study investigated wetland type and dynamic changes in Hainan Dongzhai Reserve based on three high resolution remote sensing images recorded in 2002, 2008 and 2013, respectively. The results indicated that there was little change in wetland types during 2002 to 2013. Coastal water, mangrove and culture pond were the main types of wetland in this area. The area of natural wetland trended to decline, while the total area and the numbers of individual wetland to increase. The most increased wetland types were the area of tidal creek in proportion and the culture pond in individual numbers. The changes were discovered frequently in edges of landward edge in which human activities were extensive.In aspect of the area of wetland, the dynamic degrees of the wetland changes during 2002 to 2013 in this area were small. The types of coastal water mangrove and tidal creek mainly trended to be stable. While concentrated in the types of reservoir, sandy tidal wetlands and culture pond, the dynamic degrees were big, and they were the type of wetland with swift changes.
