| 摘 要： | 探讨了利用ETM+数据得到NDVI数据进行植被变化监测的方法,并以京津源风沙治理试点延庆县为例,利用1999、2002、2006年3期ETM+数据,分析了该区1999～2006年植被指数的变化情况.研究表明,延庆县7年间(1999～2006年)植被变化十分明显,由于退耕还林等工程使弃耕的面积远大于开荒的面积:植被恢复远高于植被退化的面积,延庆县的植被总体上得到了恢复.

| Abstract: | The method of dynamic monitoring of the vegetation by NDVI data obtained from ETM+ data was discussed in this paper.Taking the Yanqing County which was the Experimental Unit for Combating Sandstorm afecting Beijing-Tianjin metropolitan region as an example,the changes of vegetation index from 1999 to 2006 in the Yanqing County had been analyzed with the ETM+ data in 1999,2002 and 2006.The results revealed that the area of vegetation changed obviously from 1999 to 2006.Because of returning farmland to forest... |
