Paper Abstract

Normalized Difference Vegetation Index (NDVI) is a widely used indicator of vegetation status. In this study, Moderate Resolution Imaging Spectroradiometer (MODIS) data was used to calculate NDVI, and then the data from NDVI combined with ground sampling are used to conduct the soil organic carbon (SOC) and nitrogen (N) research, which analyze the SOC and N contents in the surface soil of Huolin River Wetland in northeast China. The results show that NDVI, SOC and N are highly related, and NDVI can be used to study C and N spatial distribution in this wetland. It also demonstrates that herbaceous vegetation is a better indicator of wetland nutrient enrichment.
