摘要
基于1998-2007年逐旬的SPOT-VEGETATION NDVI数据,采用最大值合成MVC(Maximum ValueComposites)技术生成了每年的最大化NDVI(MNDVI)影像,结合均值法、一元线性回归分析、影像差异分析等方法研究了海南岛植被变化情况,得出岛内近10 a植被变化总体趋势及时空分布.结果显示,近10 a来海南岛植被生长状况呈下降趋势,且从东部到西部呈现明显的衰退趋势.
Based on the ten-day interval SPOT-VEGETATION NDVI data from 1998 to 2007 of Hainan Island, MNDVI （maximum normalized difference vegetation index） images were obtained for each year. The vegetation temporal-spatial variability of Hainan Island was analyzed using Maximum Value Composites （MVC）, mean value analysis, linear regression, and image differencing. The results indicated a pronounced trend of degradation across the island from the east to the west during the last decade.
