| 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。 |

| 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. |
