Abstract
A remote-sensing-based temporal net exchange estimation method of a farmland ecological system is provided. The remote-sensing-based temporal net exchange estimation method includes: obtaining low-resolution LAI remote-sensing images and high-resolution NDVI remote-sensing images during the transit of same day in a growth period of crops and constructing, associating and generating multi-temporal LAI data; in combination with daily temperature and surface solar radiation data, obtaining an LAI temporal result by simulation; comparing model simulation with remote-sensing data result and performing parameter sensitivity analysis and model uncertainty analysis to determine localized model parameters; inputting these localized parameters into the model, assimilating the high-resolution LAI result and outputting a spatial distribution temporal result of the net exchange of the farmland ecological system.
