| Based on a typical period of Luoma Lake Landsat images, and using normalized difference vegetation index (NDVI), the aquatic vegetation classification research on Luoma Lake was carried out.Using the standard deviation and classification method, the Luoma Lake aquatic vegetation was divided into 5 grades. The results showed that, the images processed by this classification method could more accurately reflect the level of regional distribution and aquatic vegetation in Luoma Lake, more accurately position mining district and ecological protection areas, and improve ecological and environmental conservation work. |
