基于NDVI指数的微山湖水生植被分级研究

Research on Weishan Lake aquatic vegetation classification based on NDVI Index

采用Landsat TM8影像,利用归一化植被指数(NDVI)方法,对微山湖水生植被进行分级研究。采用标准差分级方法,将水生植被分为5个等级,结果表明:处理后的图像能较准确反映水生植被区域分布和等级分区,提高湖区生态环境保护工作的有效性和针对性。

LandsatTM8 images, using the normalized difference vegetati on index （NDVI） method, Weishan lake vegetation Research on were graded. Using standard deviation classification method, the aquatic vegetation is divided into five levels, the results show that： the image can be more accurately reflect the post-processing of aquatic vegetation regional distribution and rank partition, enhance the effectiveness of the lake ecological environmental protection and targeted.
