| 摘 要： | 植被覆盖度是反应地区生态环境的重要指标,利用1995,2007年的两期TM遥感数据,以归一化植被指数(NDVI)像元二分法为植被覆盖度估算模型,计算阜新地区不同时期的植被覆盖度并得出阜新地区植被覆盖度等级图以及阜新地区植被覆盖度变化等级图。得出如下结论:1995年到2007年阜新地区植被覆盖度退化面积为64.817%,好转面积为6.547%,基本无变化区域为28.636%,阜新地区植被覆盖度退化严重。

| Abstract: | The vegetation coverage is an important indicator to the ecological environment of the region.Using the TM remote sensing data of 1995,2007 year and Normalized Difference Vegetation Index(NDVI) for the pixel dichotomy as vegetation coverage estimation model,it calculated the vegetation coverage of Fuxin in different periods and came to the Fuxin region vegetation coverage level maps and the Fuxin region vegetation coverage changes level maps.The paper concluded that 64.817% area of Fuxin vegetation was degr... |
