The aesthetic and environmental values of a street are greatly influenced by the selection of an appropriate arboreal species and the relation between its planted trees with the different engineering elements of a street . Street trees play a significant role in forming the architectural and aesthetic texture of the city. They, forther more, enhance material, environmental and cultural aspects of the city. This paper aimes to analyze arboreal rows in HALAB Street and to study their relation with the service and structural engineering components Of that street . Moreover, the optimal situation of these street trees was evaluated using (Li et al, 2011) equation.Results of this paper revealed prominent breaks in the arboreal rows, and that these rows contain four tree species (Jacaranda mimosaefolia Don., Ficus nitida L., Eucalyptus rostrata S., Melia azedrach L.), which served to furnish the street with monotonic beauty and humility in botanic diversity. Findings showed decrease in the optimal value of the two used botanic species where (Jacaranda) attained a mark of 6.22/10 and (Ficus nitidia) 7/10 and (Eucalyptus) 7.28/10 and (Melia) 7.53/10. Corresponding to the relation of trees to some street engineering elements, results indicated inobservance of standard dimensions between planted trees and service elements. which negatively influenced the aesthetic and position value of buildings’ and stores’ facets and guiding signs and billboards on the one hand, and risk increase on pedestrians and vehicles due to blocking vision of traffic signs and overlap of tree crowns with electricity and lighting posts on the other hand.

Research summary
تتناول الدراسة تقييم الأنواع الشجرية المزروعة في شارع حلب بمدينة اللاذقية وتأثيرها على العناصر الهندسية والخدمية للشارع. تم استخدام معادلة لي وآخرون (2011) لتقدير الحالة المثالية للأنواع الشجرية المزروعة. أظهرت النتائج وجود تقطعات بارزة في الصفوف الشجرية، واحتواء الشارع على أربعة أنواع شجرية: الجاكرندا، التين اللامع، الأوكاليبتوس، والإزدرخت. تبين أن هذه الأنواع تسببت في تشوه جمالية الشارع وتواضع التنوع النباتي. كما أظهرت النتائج عدم مراعاة الأبعاد القياسية بين الأشجار والعناصر الخدمية، مما أثر سلباً على القيمة الجمالية والوظيفية للشارع وزاد من مخاطر الحوادث المرورية. توصي الدراسة بضرورة اختيار الأنواع النباتية المحلية المناسبة، مراعاة النسب المثالية من الوحدات التصنيفية، والاهتمام بعمليات الرعاية والتقليم لتحسين البيئة العمرانية والجمالية للشارع.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً لتقييم الوضع الراهن للأشجار في شارع حلب، إلا أنها تفتقر إلى بعض الجوانب التي قد تعزز من قوتها العلمية. أولاً، كان من الأفضل تضمين مقارنة مع شوارع أخرى في المدينة أو في مدن أخرى لتقديم رؤية أشمل. ثانياً، لم تتطرق الدراسة بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل التلوث والازدحام المروري على صحة الأشجار. ثالثاً، كان يمكن تعزيز الدراسة باستخدام تقنيات حديثة مثل الاستشعار عن بعد لتحليل البيانات بشكل أكثر دقة. وأخيراً، يجب أن تتضمن التوصيات خطة تنفيذية واضحة ومحددة لتحسين الوضع القائم.

This study was conducted in Syria Street, which connects between Yemen Square and Republic Square in Latakia City. This paper cares to analyze arboreal rows in SYRIA Street and to study their relation with the service and structural engineering com ponents Of that street . Moreover, the ideal state of these street trees was evaluated .Results of this paper revealed, that the arboreal rows contain two botanic species (Ficus nitida L, Jacaranda mimosaefolia Don.), which served to furnish the street with monotonic beauty and humility in botanic diversity,and prominent breaks in these rows. Findings showed an ideal decrease in the value of the two used botanic species where (Ficus nitidia) attained a mark of 6.8/10 and (Jacaranda mimosaefolia) 6.34/10 . Corresponding to the relation of trees to some street engineering elements, results indicated inobservance of standard dimensions between planted trees and service elements. which negatively influenced the aesthetic and position value of buildings’ and stores’ facets and guiding signs and billboards on the one hand, and risk increase on pedestrians and vehicles due to blocking vision of traffic signs and overlap of tree crowns with electricity and lighting posts on the other hand.
The paper proceeds to review the concept of Residential Urban Spaces and their classification, and to limit the variables affecting the performance of the spaces and identify the ways to measure these variables. Then, it conducts a field survey of a variety of spaces in the City of Lattakia. The paper also proceeds to conduct a questionnaire to the urban spaces users and the residents of the surrounding segments of the population in order to identify the users’ opinions and reviews on the current status of the space performance and identify the most important needs and activities favored by the users within the space. It also identifies the reasons behind selecting certain spaces rather than others. After that, the paper proceeds to analyze the data in order to develop a mathematical model that determines the most important variables that affect the performance of the space, positively or negatively. Consequently, a mechanism will be set up to boost the performance of the Residential Urban Spaces by influencing the most powerful variables affecting the spaces and rejecting the weaker ones. Finally, making recommendations to activate the spaces and make it a safe interactive human, socio- cultural environment.
The Study focuses on the contemporary planning applications in shaping the urban structure of the residential areas in general and the spatial formation in particular, according to a schematic structure that depends on classification of these space s by kind, function of these special formation and their distinguished characteristics. The study focuses on the gradual scales of the formed spaces within the urban residential structure according to their functions, starting with the external courtyards surrounded by residential buildings whose construction in open space differs from the one in closed space, according to the predominant climatic conditions, then we move to the spaces of motorcar streets and pedestrians roads that have the dynamic and vitality characteristic by the multiplicity of uses, the functions, and the changes of its design structure. Spaces surrounding the public and service buildings form some special distinctive structural points especially when they complement each other with the surrounding buildings in architecture and volume. The formation of aesthetic-visual image in the urban spaces and the visual recognition mechanism divides the urban spaces into three principal types and discusses the relationship between shapes, volumes and colors of the building that form the space and visual sensation with the homogeneity and extension of space. Then the research studies various samples of the urban residential structure of Lattakia city and the spatial formation by performing general classifications of the urban spaces forming this structure according to the type and function of each. Then, we conclude the advantages and disadvantages of the schematic solution and understand the reasons of the negative aspect to be avoided in future.
the research aims to know the methods of Landscape Architecture, and to choose the green elements appropriate for them, this can be achieved after knowing the climatic conditions that prevail in different regional in general and in the Syrian Arab Republic in Particular.
The experiment of high rise buildings in Amman with commercial buildings is a leading experience in urban development of high rise buildings. The purpose of this research is to look at the effect of these buildings from a human dimension point of view. This paper sheds light on the commercial building within Amman Great Municipality with a case study focusing on Al-Hussein Mountain Area with special attention to these buildings as invited landmark; also as an open urban spaces scape element and to find out the impact of such structure on the local people and their behavior within Amman.
