摘要
根据1984~2015年间4景TM、ETM遥感影像图,利用ENVI软件输出4幅不同时期杭州湾滨海湿地的分类图,分析其变化规律,建立杭州湾滨海湿地质量评价体系。结果表明,30 a间杭州湾滨海湿地中的自然湿地逐步向人工湿地转变,必须加强滨海湿地保护措施。
Based on the four phases of remote sensing images(1984~2015),we used ENVI software to get four Hangzhou Bay coastal wetland classification figures.And then,we analyzed the relative change rules,and established a Hangzhou Bay coastal wetland quality evaluation system.The results show that natural wetlands are turning to constructed wetlands in the past 30 years.It's important to strengthen the consciousness of protecting coastal wetland.
