基于Landsat 7影像的骆马湖菹草时空分布研究

摘要

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 ac-curately 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.%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。
