تتحدد القيمة الجمالية و البيئية لأي شارع إلى حد بعيد باختيار النوع الشجري المناسب و بعلاقة أشجاره المزروعة مع مختلف العناصر الهندسية للشارع . تلعب أشجار الشوارع دوراً هاماً في تشكيل النسيج العمراني و الجمالي للمدينة , كما تعمل على تعزيز الجوانب المادية و البيئية و الثقافية للمدينة. تناول البحث تحليل الصفوف الشجرية لشارع حلب و دراسة علاقة أشجاره مع المكونات الهندسية الإنشائية و الخدمية له. كما تمَّ تقدير الحالة المثالية للأنواع الشجرية المزروعة بهذا الشارع باستخدام معادلة لي و آخرون (Li et al,2011). أظهرت نتائج البحث وجود تقطعات بارزة في الصفوف الشجرية للشارع .كما بيَّنت أن الصفوف الشجرية في شارع حلب تحتوي على أربعة أنواع شجرية Ficus nitida L., Jacaranda mimosaefolia L. ,.S Eucalyptus rostrata ., Melia azedrach L , مما سبب تشوهاً لجمالية الشارع و تواضعاً في الغنى النباتي لهذه الصفوف . كما كشفت نتائج البحث عن تدني القيمة لدرجة مثالية بعض الأنواع المستخدمة بالشارع كالجاكرندا الذي حاز /6,22/درجة , في حين كانت هذه القيمة مقبولة في نوع التين اللامع /7/ درجة و نوع الأوكاليبتوس المنقاري 7.28 درجة و نوع الازدرخت 7.53 درجة من أصل /10/ درجات. فيما يخص علاقة الأشجار ببعض العناصر الهندسية للشارع , أظهرت النتائج عدم مراعاة الأبعاد القياسية بين الأشجار المزروعة و العناصر الخدمية. أثرت هذه الحالة سلباً على القيمة الجمالية لواجهات الأبنية و المحلات التجارية و على درجة وضوح اللوحات الإرشادية و الإعلانية من جهة , كما تزايدت المخاطر على المشاة و الآليات نتيجة حجب رؤية الإشارات المرورية و تداخل تيجان الأشجار مع أعمدة الإنارة و الكهرباء من جهةٍ أخرى .
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.

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.
