| 摘 要： | 以天津国家级盘山风景名胜区为研究区,利用2004-2007年覆盖天津国家级盘山风景区的中巴资源卫星数据,用主成分变换方法,对原始CCD影像进行提取,与归一化植被指数(NDVI)相结合,进行土地利用/土地覆盖(LULC)的提取。通过研究发现,2007年6月项目区植被面积为85 km2,9月为97 km2,与2004、2005年同期植被面积相比均有较大变化。

| Abstract: | Based on ZY01/ZY02 series images in 2004 and 2007,Principal Component Analysis(PCA) was used to transform the original to the new band combination.Due to the distinctive distribution of different land uses in NDVI space,NDVI was partitioned into the first three PCA components to classify land covers and LULC maps were created for each of the three studied years.The LULC maps showed that vegetation acreage was approximately 85 km2 in June,97 km2 in Sep.2007,had changed a lot during the study period(2004-2007... |
