2000—2020年花场湾红树林变化监测及驱动力分析

Monitoring changes of mangrove from 2000 to 2020 in Huaba Bay and its driving force analysis

本文选取海南省澄迈县的花场湾红树林湿地为研究对象,采用遥感技术中的人机交互方式,对2000年、2005年、2010年、2015年和2020年五个时段的Landsat影像数据进行提取分析,得出花场湾红树林湿地的自然分布状况及变化趋势。在此基础上,进一步选取六种景观指数并对花场湾红树林进行了定量分析,直观地反映其景观破碎化的过程。同时,对影响红树林变化的因子进行了特定分析,为花场湾红树林湿地区域的生态保护与管理提供了一定的科学依据。

In this paper,the mangrove wetland of Huaba bay in Chengmai county,Hainan province,is selected as the object of this study,and the human-computer interaction in remote sensing technology is used to extract and analyze Landsat image data for five time periods,including 2000,2005,2010,2015 and 2020,to derive the natural distribution of Huaba bay mangrove wetland and the trend of its changes.On this basis,six landscape indices have been further selected to quantitatively analyze the mangrove forest in Huaba bay,which visually reflects the process of its landscape fragmentation,and at the same time,specific analysis is conducted on the factors affecting the changes of mangrove forest,thus providing a certain scientific basis for the ecological protection and management of Huaba bay mangrove wetland area.
