دراسة التمدد العمراني باستخدام الاستشعار عن بعد و نظم المعلومات الجغرافية (GIS)‎ : حالة تطبيقية على الضاحية الجنوبية لبيروت

الملخص EN

The urban expansion has negative consequences like the increase in built-up areas and those allocated by roads, the decrease of green areas and the quality of existing public services and the increase of violence towards public and private property.

This study aims to analyze the urban expansion in Beirut southern suburb as a case for more than 50 years using Remote Sensing (RS) and Geographic information system (GIS) in order to treat the actual situation and limit the future extension.

This study analyzes urban expansion between 1963 and 2016 according to two main factors: Land-use and road network expansion.

To study those factors, a comparison has been done between the land-use map and the road networks map using areal and satellite images for the study area.

This study shows the increase in built area to accommodate the population increase, the regression of green areas, the spread of spontaneous grouping, building violations and violence towards public and private property as a result of the increased numbers of arrivals to the region and the increase of non-permeable areas (roads and built areas) which increase the flooding probability during winter.

In order to limit the urban expansion, it was supposed to modify the building law in the study area.
