Precision agriculture has the potential to improve crop yield and resource use efficiency while protecting the environment. Effective monitoring of crop biomass during the growing season is important for making in-season management decisions. One commonly used active crop canopy sensor for non-destructive estimation of crop biomass is the GreenSeeker sensor. The GreenSeeker normalized difference vegetation...
Grassland ecosystem is one of the most important terrestrial ecosystems in China. Grassland aboveground biomass (AGB) is not only the material base for maintaining grassland ecosystem, but also the most direct indicator to reflect grassland status. AGB determines the herbivore carrying capacity in grassland ecosystem. Therefore, it is important significance to retrieve AGB to study the regional carbon...
In this study, we evaluated the precision of different regression models correlating grasslands aboveground biomass (AGB) and its corresponding vegetable index (VI). We further identified changes in the size and distribution of AGB and explored the relationships between interannual AGB pattern and climatic factors in the eastern Inner Mongolia grasslands by integrating AGB data collected from 520...
In this paper, the response of ALOS (the Advanced Land Observing Satellite) PALSAR (the Phased Array type L-band Synthetic Aperture Radar) data to the forest biomass was analyzed in the Qilian Mountain area within Gansu province, western China. Due to not enough field biomass, the Light Detection and Ranging (LiDAR) data were used to extract biomass in a 20 m ?? 20 m cell. Then, the relationship between...
