摘要:: 围海造地是解决土地矛盾的重要途径. 大型围填海工程不仅对海洋生境造成深远影响,围垦区内景观生态格局变化更是直接影响着区域的生态变化. 本文选取江苏条子泥垦区为研究对象,采用2010、2015、2018和2020年4期遥感影像和环境生态调查等数据,研究垦区内景观格局演变,结合景观指数变化,采用面积转移矩阵模型分析驱动因素,进而提出生态保护措施. 研究结果表明:建设初期各类景观面积变化快速,破碎化增大,修复期景观破碎化趋势降低. 开发与生态保护修复是围垦区景观格局演变的主导驱动力,协调好围垦区开发与生态保护,可以优化改善景观格局,大幅度提升垦区生态功能.

Abstract:: Land reclamation is an important way to resolve land conflicts. Large-scale reclamation projects not only have a profound impact on the marine habitat,but also the changes in the landscape ecological pattern in the reclamation area directly affect the regional ecological changes. This paper selects Tiaozi mud reclamation area in Jiangsu as the research object,and uses data such as remote sensing images and environmental and ecological surveys in 2010,2015,2018 and 2020 to study the evolution of landscape pattern in the reclamation area,combined with landscape index changes,using the area transfer matrix model to analyze the driving factors,and then put forward ecological protection measures. The research results show that in the early stage of construction,the area of various landscapes has changed rapidly,fragmentation has increased,and the trend of landscape fragmentation has decreased during the restoration period. Development and ecological protection are the leading driving forces for the evolution of the landscape pattern in the reclamation area. Coordinating the development and ecological protection of the reclamation area can optimize and improve the landscape pattern and greatly enhance the ecological function of the reclamation area.
