Modelling Above ground net primary production of Sabalan rangelands using vegetation index and non-linear regression
Background and objectives: Alongside with the progresss in satellite sensors, their role on obtaining information and study of the environmental events and phenomena have become increasingly important. One of these precious data which is the basis for many planning and decision making in rangelands, is the above ground net primary production assements. The traditional method of estimating ANPP ...
متن کاملGround State Quarkonium Spectral Functions Above Deconfinement
We discuss the temperature-dependence of S-wave quarkonium spectral functions in a nonrelativistic Green’s function approach and compare these to lattice QCD results.
متن کاملRemote Sensing of Above-Ground Biomass
Accurate measurement and mapping of biomass is a critical component of carbon stock quantification, climate change impact assessment, suitability and location of bio-energy processing plants, assessing fuel for forest fires, and assessing merchandisable timber. While above-ground biomass includes both live and dead plant material, most of the recent research effort on biomass estimation has foc...
متن کاملAbove-ground biomass and structure of 260 African tropical forests
We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha⁻¹ (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha⁻¹) similar to...
متن کاملCost and Utilization of above Ground Biomass in Thinning
Billy Watson and Bryce Stokes ABSTRACT: The cost and utilization were compared for a thinning operation removing the stems as roundwood with a flail chipper operationThe flail chipper operation recovered an additional 4.2 tons of acceptable chips per acre which resulted in a higher return to the site. There was little difference in the cost of acceptable chips delivered to the digester between ...
