Abstract

Summary

The purpose of the presented study is to investigate seasonal relationships between field-measured LAI and satellite-derived spectral vegetation index for oak communities on the example of the forest parks in Mykolaiv city. Furthermore, possibilities of quantitative mapping of vegetation amount in the investigated urban oak forests are explored. Data were collected during the vegetation period 2018 in a city park (in Mykolaiv, which is located in Ukraine's steppe. To cover the main stages of oak's seasonal development, LAI data were measured from the end of April until the end of October in 2018 at 21 installed sample plots. For estimating the LAI of the oak forest park six seasonal NDVI images obtained from Sentinel-2 time series data were used. It was foun that, the LAI-NDVI relationship is poor during periods of maximum LAI. Considering data obtained during the leaf production and leaf senescence periods for all years enables to achieve strong regressions, w hich character is non-linear. The LAI estimation for the study site is showing the good coefficient of determination (R2=0. 795), with RMSE=0. 196. The received regression relationship is could be proposed for LAI estimations and mapping of oak forest stands all over the region.
