كشف التغير للغطاء النباتي لحوض وادي الحيسية و وادي بوضة (بشمال مدينة الرياض)‎ باستخدام بيانات spot5 عالية الوضوح المكاني خلال الفترة الزمنية (2005م)‎ و (2015م)‎

Abstract EN

The study has aimed at monitoring the change on the vegetation in Al-Haysia valley basin and Boudha valley basin.

To achieve this study, the change on the vegetation in both basins was monitored through using the high-definition spatial satellite data (spot5) for the years (2005) and (2015) and through using the (NDVI) index to calculate the density of the vegetation in the study area as well.

The study has found that there is an increase in the density of the vegetation between the years of 2005 and 2015 in both basins.

That such increasing reached to (1.59)km2 in Al-Haysia valley basin and (1.42)km2 in Boudha valley basin, respectively.

Also, the study has come out with many recommendations.

That the most important one is to tighten control over the exceedings that committed by somebodies in the dry basins.

Such exceedings are represented in dumping the construction waste and pollutants; establishing industrial projects and drilling projects; and planting on the banks of the basins.

That such doings cause a change in the streams of tributaries and torrents; and also a change in the properties of the soil and plants that affect the entire basins environment over time.
