| 摘 要： | 以1993年、2001年和2006年的TM遥感影像图为信息源，基于NDVI和植被覆盖度定量模型，利用ENVI4．2、ARCGIS等软件获取了鞍山市千山风景区归一化植被指数差值变化图及覆盖度等级图，并进行了定量对比分析．结果表明：2001年与1993年相比，低覆盖与高覆盖面积均有增加，而中高覆盖地区其质量有所下降，局部生态退化．2006年与2001年相比，大部分地区高覆盖增加，质量上升，生态环境向良好方向发展． |

| Abstract: | The TM images in the years of 1993,2001 and 2006 were taken as information source to be analyzed,The coverage grade map and vegetation index dynamic map were obtained based on NDVI and quantitative model of vegetation coverage,by means of ENV14.2 software and ARCGIS.The quantitative analysis revealed that both areas of low coverage and high coverage in 2001 had increased than those in 1993.While the quality of middle and high grade vegetation had degraded,and ecological regression had happened in partial ar... |
