مع ازدياد عدد السكان و ارتفاع مستوى المعيشة و التقدم الصناعي و التقني السريع تنوعت و ازدادت كميات النفايات الصلبة الناتجة من الأنشطة البشرية المختلفة و أصبحت عملية التخلص منها من ابرز المشاكل التي تواجه المدن و التجمعات البشرية نظراً لما تشكله هذه النفايات من أخطار على البيئة و مواردها الطبيعية و على صحة الإنسان و سلامته. لذلك فإن وضع نظام إدارة متكامل للنفايات الصلبة اصبح من أهم عناصر استراتيجيات تطوير المدن .
تتضمن الإدارة التقليدية للتخلص من النفايات البلدية الصلبة عمليات جمع النفايات و نقلها و ردمها أو حرقها و قد تطور مفهوم التخلص من النفايات الصلبة خلال العقود السابقة و بدأت برامج إدارة النفايات تركز على استخدام البرامج الحاسوبية مثل برنامج نظم المعلومات الجغرافي الذي يساعد في عملية التخطيط البيئي للمدن و اختيار الحلول المثلى و الاكثر اقتصادية .
و تتضمن هذه الدراسة استخدام تقنية برنامج نظم المعلومات الجغرافية في تخطيط و اختيار المسارات المثلى لجمع و ترحيل المخلفات الصلبة من حاويات مدينة اللاذقية حيث يخضع اختيار هذه المسارات على معادلتي الطول و الزمن فيتم اختيار المسار الاقصر بالنسبة للطول مع الاخذ بعين الاعتبار القواعد المرورية و اتجاهات السير ضمن الطرقات أما بالنسبة للزمن فيأخذ المسار ذو المسافة الاقصر وفقا للسرعات المحددة لكل طريق.
With the increasing population, the rising standards of living, industrial progress and
rapid technological advancement, solid waste has varied and increased in amount as a
result of various human activities. Thus, waste disposal has become one of the main
problems facing cities and human populations because of the dangers posed by this waste
to the environment and natural resources and health. Therefore, the development of an
integrated management system for solid waste has become one of the most important
elements of urban development strategies.
Traditional management of municipal solid waste disposal, which includes
collection, transfer and backfilling or burning operations, has evolved the concept of
disposal of solid waste during the previous decades and begun waste management
programs that focus on the use of computer programs such as geographic information
systems, which help environmental planning for cities, and selection of the most optimal
and economical solutions and.
This study includes the use of geographic information systems software technology
in the planning and selection of the optimal paths to collect and relay solid waste
containers in the city of Latakia. In fact, selecting these routes undergoes the equations of
length and time as to choose the shortest path, taking into account traffic regulations and
diesctions in the streets. As for time, it takes the shortest path in terms of speeds specified
for each road.
