摘要
基于2013年国产资源遥感卫星数据和Google Earth高分数据,利用ArcGIS9.3及Eardas9.2软件,对研究区域的遥感影像进行克里金插值分析,在此基础上得出研究区域遥感影像的植被指数NDVI,最后反演出该区域的植被覆盖度结果。通过与该区域的真实植被覆盖度进行比较分析,得出了基于克里金插值法的植被覆盖度分析方法,该方法对植被覆盖度分析有一定的实际性的参考意义。此次实验研究了黄河源头姊妹湖扎陵湖、鄂陵湖区域的植被覆盖度,同时也是三江源地理国情监测的一部分。
Based on resources remote sensing satellite data of China and the Google Earth high resolution data in 2013, using ArcGis9.3 and Eardas9.2 software, firstly, Kriging interpolation analysis of remote sensing images of the study area was conducted. On the basis of this, ND- VI from the remote sensing image was obtained, at last, the vegetation fraction was inversed. Concluding the vegetation fraction analysis meth- od based on Kriging interpolation method, this method has certain practical reference for vegetation fraction analysis. The experimental study on the vegetation fraction of the YellOw .Riversisters Lake Ztiling and Elirig Lake area, at the same time, it is also a part of the Sanjiangyuan of geographic conditions monitoring.
