| 摘 要： | 通过综合分析"黄苔"、芦苇、明水体和陆地等地物在EOS/MODIS图像上不同波段的光谱特征,提出了利用EOS/MODIS可见光、近红外波段数据提取"黄苔"信息的方法.结合乌梁素海"黄苔"实地考察资料和高空间分辨率的中巴资源卫星CBERS/CCD数据对MODIS数据监测"黄苔"的结果进行了比对验证.研究结果表明,本文提出的方法可以对"黄苔"进行有效的监测.同时提出了简单可行的去除程辐射影响的大气校正方法,利用MODIS 2008年5-10月的数据对内蒙古乌梁素海的"黄苔"灾情进行了动态监测,获得了乌梁素海"黄苔"灾情发生发展的特征信息,乌梁素海在2008年5月初开始出现"黄苔",6-7月份发生大面积"黄苔"暴发,进入8月以后"黄苔"开始逐渐消退,10月份基本消失,并初步分析了"黄苔"暴发的原因.

| Abstract: | The spectral characteristics of the " Huang Tai" algae, reed, water body and land in the EOS/MODIS image of Lake Ul-ansuhai Inner Mongolia were analyzed and the method of extracting the algae information was put forward based on visible, near-infrared data of EOS/MODIS. Compared with the field measured data and CBERS/CCD data with 19.5m spatial resolution, EOS/ MODIS method was validated. At the same time, the simple and feasible method to remove the effects of path radiance was put forward in MODIS image's atmospheric correction process. The results of algae dynamically monitoring using MODIS data started from May to October, 2008 showed that "Huang Tai" algae began to appear in Lake Ulansuha in early May 2008. During the period June to July, the algae bloomed, and the algae began to subside in August and disappeared in October. |
