摘  要:
以焦作市2000年和2013年Landsat TM影像为基础,依据归一化植被指数和像元二分模型,对焦作市近13 a来植被覆盖度变化情况进行分析。研究表明,2000—2013年焦作市植被覆盖度总体比较低,其中修武县的植被覆盖度是所有区域中最高的;与2000年相比,2013年焦作市植被覆盖度总体增加,其中低及以下植被覆盖度区域面积明显减少,中低及以上植被覆盖度区域面积均有明显增加。

摘  要:
Based on the Landsat TM images of Jiaozuo city in 2000 and 2013,the change of vegetation coverage from 2000 to 2013 was studied using the normalized differential vegetation index(NDVI) and dimidiate pixel model. The results showed that the vegetation coverage of Jiaozuo was low in general,the vegetation coverage in Xiuwu county was the highest. Compared with 2000,the vegetation coverage increased in 2013,the low and under vegetation coverage areas decreased obviously,the low-medium and above vegetation coverage areas increased in 2013.
