基于ASTER遥感影像植被信息的提取--以青海湖地区为例

草地植被是我国最重要的植被类型之一,是重要的可更新资源和畜牧业的原料基地,又是地球表面天然的绿色屏障,对于人类的生存和发展起着重要的作用。青海湖及湖周丰茂的草地植被不仅对湖区生态环境有着举足轻重的控制及调节作用,而且对保护东部生态环境具有重要作用。所以及时有效的对植被变化进行准确的检测,将不仅直接关系到该区畜牧业的发展,而且关系到青海湖生态环境的状况,以及生态需水量的检测。本文对ASTER遥感图像进行解译,提取植被指数进行比较分析,希冀对青海湖地区的可持续发展提供一些帮助。

Extraction of Vegetation Information Based on the ASTER Remote Sensing Image--taking the Qinghai Lake area as the example

The lawn is one of the most important vegetation types,it is the renewable resource and raw material of husbandry in our country.It is also,the natural green protective blockade of the earth which plays an important role to human being.The water and the lush lawn around the Qinghai lake play the key role in control and regulation note only of the lake's ecological environment,but also to the eastern part.Therefore,the accurate prompt and effective examination on the vegetation change play an important role in the animal husbandry development,the Qinghai Lake ecological environment condition,and the ecology water demanding in this area.In this paper,the authors use the ASTER remote sensing image to extract vegetation index information and carry on the comparative analysis.
