The nutrient status of Spartina Anglica should be monitored dynamically in order to manage scientifically it, enhance conserve level, and improve its productivity. The author chose leaf spectra of Spartina Anglica located in the same sample plot and tested leaf reflectance and extracted chlorophyll a, b, and chlorophyll a and b concentration for leaf, stem, and mixture of leaf and stem. Seven single...
Spartina Anglica has been widely used to protect tidal flat and clarify water quality, and studying its spectral reflectance characteristics would be helpful to understand its nutritional status, which usually help to improve and promote the halophyte's cultivation and protection. A total of 8 sample sites in the tidal flat, Lianyungang, had been selected to test their canopy reflectance spectra of...
Using the data of wheat spectrum and water content in 6th April and 23rd April, we figure out the values of NDVI, NDWI, GVMI, PVI and WI, which are among the most frequently used water indices, and make correlation and regression analyze between these indices and EWT and FMC, two indices indicate the water content of wheat leaves. Through analysis and comparison, we find that FMC has a better correlation...
The temporal evolution of decadal NDVI composition is regarded as an effective time window which is able to show the natural seasonal variations. In this study, a time series of SPOT-VEGETATION Normalized Difference Vegetation Index (NDVI) data with 1×1 km² spatial resolution are used to detect the vegetation cover change in west Songnen plain, Northeast China during the period of 1998 to 2006. Our...
