ESTIMATION OF ACACIA SENEGAL TREE BIOMASS USING ALLOMETRIC EQUATION AND REMOTE SENSING, NORTH KORDOFAN STATE, SUDAN

摘要

This paper trying to tackle the estimation of the woody biomass of Acacia Senegal tree by applying allometric equations for ground data combined with satellite data sets. The current study was conducted in Um Habila Forest (2.7 square Kilometres) which is located in El Rahad locality in North Kordofan State, Sudan. A primary data were obtained by application random sampling technique, counting a total of 27 tree. The tree coordinates, tree diameter/diameters, were recorded. Sensor data were acquired from SPOT-5 (08.11.2009) satellites and integrated with the in-situ data. The study findings revealed that the mean diameter of Acacia Senegal tree was 7.31 cm ± 1.68 cm. The tree above ground biomass (TAGB), tree below ground biomass (TBGB) and total tree biomass (TTB) of Acacia Senegal were found to be 15.15± 9.01 kg, 3.03 ±1.80 kg, and 18.18±10.81 kg, respectively. Remotely sensed data were integrated with the terrestrial method for creating and correlating the relationship between them. The application of allometric equations is useful as non destructive method for biomass and the application of remote sensing is recommended for biomass estimation in wide coverage area.
