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. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
