| 摘 要： | 选取植被指数和温度作为湿地保护区划定的基本依据，采用感测范围广、获取信息方便的NOAA／AVHRR影像作为主要数据源，反演南中国海区域的归一化植被指数NDVI、海面温度和陆地表面温度。对反演结果进行分析，确定湿地保护区的NDVI阈值和温度阈值，再对各个参数的阈值进行空间分析，最终确定南中国海重要湿地地址和范围。最后把确定的保护区域与联合国环境署／全球环境基金确定的湿地示范区作对比研究，发现根据NDVI与温度确定的重要湿地包括了6个重要湿地示范区中的5个。

| Abstract: | In the paper,the demarcation of wetland protection area is based on the vegetation index and temperature.The RS data(NOAA/AVHRR) is used to calculate the normalized difference vegetation index(NDVI) of South China Sea and the temperature of the earth and sea surface.By analyzing these indexes the vegetation index threshold and temperature threshold of wetland protection area are made;then choose the protection area within the limit of these data and identify the range of the wetland protection area ultimately by using buffering and overlay analysis functions in GIS.By comparing these areas with the demonstrative areas made by UNEP/GEF,five of these areas based on the NDVI and temperature are among the six important demonstrative areas. |
