Study on The Relationship between Vegetation Index And Bird Diversity in Beidagang Wetland

Abstract Birds are an important part of wetland ecosystem. With the development urbanization, bird vegetation is destroyed seriously, threatening diversity. In view this, this paper studied dynamic changes NDVI (Normalized Difference Vegetation Index) and three diversity indexes (Shannon-Wiener index, Simpson Pielou index), explored relationship between two, based on survey data Landsat 8 remote sensing images from 2015 to 2019 in Beidagang Wetland. The results showed that: Although growth condition plants changed poor better due ecological water rehydration measures adopted later period, leveled off except 2018. Spearman correlation analysis that Shannon-Wiener index was highly negatively correlated with NDVI, slightly indicating Wetland had much less impact than other habitat factors, could not play a leading role.
