摘 要: | 利用EOS/MODIS卫星遥感数据,对鄂尔多斯市2002-2012年地表植被指数及变化成因进行了分析。鄂尔多斯市近11年来NDVI虽具有一定的波动性,但整体呈明显的增长趋势,与降水量呈现显著的正相关关系。NDVI大于0.4以上的面积逐年增加,表明该地区植被覆盖率逐年增加,生态环境得到有效改善。分析其主要原因,在于生态建设政策及资金投入力度的大幅增加。

Abstract: | The surface vegetation index and its variation causes from 2002 to 2012 of Ordos are ana-lyzed in this paper, using the EOS/MODIS satellite remote sensing data. The results show that: in recent 11 years, although NDVI has some volatility in Ordos, overall shows an obvious growth trend,which is a significant positive correlation with precipitation, area of NDVI more than 0.4 increasing year by year. So the area of a substantial increase in the ecological construction policies and capital investment, ecological environment has been effectively improved. |
