| 摘 要： | 以TM影像为数据基础,以大庆、安达等8个县为例进行对比,利用归一化植被指数(NDVI)分析黑龙江省西部地区草场荒漠化在1996～2007年间的变化趋势。研究发现1996～2007年间,黑龙江省西部草场荒漠化面积有所增加,荒漠化程度日趋严重。研究表明:以卫星影像为基础使用遥感技术对荒漠化程度进行研究的方法,相比传统方法更加迅速、直观,对指定区域进行动态监测,优势更加明显。

| Abstract: | Based on TM image for data,compared the eight counties including Daqing,Anda,etc,using Normalized Difference Vegetation Index（NDVI）,it analyzed the trend of the pasture desertification in the western region of Heilongjiang Province from 1996 to 2007.It found that the area of desertification in Western Region of Heilongjiang province has increased,the levels of desertification had become increasingly severe from 1996 to 2007.The results showed that the method of remote sensing based on the satellite images was more convenient and intuitionistic comparing with the traditional method,and was more preponderant in dynamic monitoring of the designated region. |
