现代黄河三角洲湿地时空变化及其保护对策

The Spatio-temporal Changes and Protection Measures of Wetlands in the Modern Yellow River Delta

现代黄河三角洲湿地在国际湿地研究中占有重要地位,然而近些年来,该地区湿地存在一定程度的退化.因此,以1985 ～2014年中的四期遥感影像为数据源,采用监督分类与目视解译相结合的方法获取现代黄河三角洲湿地分布状况;分析了现代黄河三角洲各湿地类型的变化趋势及存在的主要问题,并提出了相应的湿地保护对策.

The wetlands in the Modem Yellow River Delta occupy an important position in the world. However, the wetlands in the area have been degraded in some ways in recent years. Therefore, using a combination methods of supervised classification and visual interpretation, the wetland distribution in the Modem Yellow River Delta were extracted based on the 1985-2014 Landsat TM images. Moreover, the spatio-temporal change trends and the main problems of the wetlands were analyzed, and the corresponding wetland protection measures were proposed.
