【 摘 要 】

In the last few years the vegetation areas in Bekaa region of Lebanon are decreasing against urban sprawl, from here it came the idea of the application of available remote sensing indices, to distinguish bare-soil areas from urban region which plays an important role in the ecosystem. This paper introduces and use a set of new indices for mapping built-up and bare land areas and able to map and distinguish built-up and bare land areas and was tested by mapping these indices in Bekaa valley. In this study we applied 3 remote sensing indexes instead of automatic bare soil extractions existing methods, using Landsat OLI/TIRS of July 2014. Bare soil Index (BI), Normalized Difference Bareness Index (NDBaI) and The Enhanced Built-Up and Bareness Index (EBBI). Contrary to bare land indices we applied 3 urban indices, Difference Built-Up Index (NDBI), Index-based Built-Up Index (IBI), Urban Index (UI) and providing a comparison between them to conclude a degree of effectiveness of them in order to mapping bare-soil areas of Bekaa valley The results of this study could be in the future a remote sensing practical method for monitoring Bekaa valley land use.
