摘要:
近年来,骆马湖湖区菹草(麦黄草)暴发性繁殖引发了一系列水质问题。通过研究,判读2012—2013年不同时间段的骆马湖landsat 7影像,可以发现,Landsat 7影像可以准确反映湖区菹草分布,区域化明显;同时发现菹草分布受多种因素影响,人类采砂和围网养殖等活动对其影响显著。

The Temporal and Spatial Distribution of Potamogeton Grispus in Luoma Lake Based on Landsat 7 Image
CAO Yi,WANG Hui
Abstract:
In recent years, lake of Potamogeton crispus (yellow wheat grass) explosive reproduction caused a series of water quality problems. By studying the Luoma Lake Landsat 7 image at different time in 2012-2013,we can find that Landsat 7 imaging can accurately reflect the lakes Potamogeton crispus distribution; at the same time,Potamogeton crispus distribution is affected by many factors, especially human activities such as mining and aquatic breeding.
