يعتبر التخطيط الإقليمي في الوقت الراهن أحد ركائز الدولة و مقياساً لتطورها، و ذلك لأن التخطيط يعمل على إظهار المشاكل الحالية أو المستقبلية و يضع الحلول المناسبة لها، و مما لاشك فيه أن السكان هم الهدف الرئيسي من أي عملية تخطيط، و ذلك بتأمين مختلف متطلبات الحياة للأعداد المتزايدة منهم عاماً بعد عام، و بالتالي فإن إيجاد المسكن الملائم يعد من أولى الخطوات في عملية التخطيط. تعد مشكلة النمو السكاني من أبرز المشاكل التي تعاني منها الدول في الوقت الراهن و يظهر هذا جلياً في مراكز المدن و الذي ينتج عنه مشاكل عديدة كالسكن العشوائي مثلاً. قمنا في هذا البحث بدراسة مكانية لتحديد الموقع الأفضل لإنشاء مدينة جديدة، و ذلك لاحتواء الأعداد المتزايدة من السكان ضمن محافظة اللاذقية التابعة للجمهورية العربية السورية، بالإضافة إلى إجراء دراسة سكانية لتحديد الزيادة المستقبلية في عدد السكان. و قد أثبتت تقنيات نظم المعلومات الجغرافية (GIS) كفاءتها في إدارة البيانات المكانية و الوصفية و تحليلها، لذا تم الاعتماد عليها للقيام بتحديد الأماكن الملائمة للتوسّع العمراني وفق مجموعة من المعايير التي تم تجميعها من مجموعة من الأبحاث و التي تؤثر في عملية اختيار هذه المناطق، و ذلك عن طريق أدوات التحليل المكاني الموجودة ضمن برامج الــ (GIS)، للوصول إلى المناطق الملائمة للتوسّع لاستيعاب النمو السكاني المفترض.
Regional planning is currently one of the pillars of the state and a measure of its development, because planning works to show the current or the future problems, and puts the appropriate solutions. So there is no doubt that the population is the main goal of any planning process by ensuring the various requirements of life for the increasing number of them year after year. Finding adequate housing is therefore one of the first steps in the planning process. The problem of population growth is one of the most prominent problems facing countries at present time. This is evident in city centers, which results in many problems such as informal housing. In this study, we had a spatial study to determine the best location for establishing a new city in order to accommodate the increasing number of population within the Lattakia Governorate (Syrian Arab Republic), and we also achieved a population study in order to determine the future population growth. Geographic information systems (GIS) have proven its efficiency in spatial and descriptive data management and analysis, so they have been relied upon to determine the appropriate places for urban expansion based on a set of criteria collected from a range of research that affect the selection process of these areas, through spatial analysis tools within the GIS software to reach the appropriate areas of expansion to accommodate the expected population growth.

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.
Cities form the major urban environment that human beings live and do their various activities, but the
population pressure and the increasing population density in cities led to the expansion of cities either
spontaneously or according to plans re
leased by governments aiming to improve expansion regions to be
new growth centers that positively contribute in supporting cities that suffer from overcrowding,
deterioration of facilities and the lack of spaces suitable for urban expansion. The process of developing
specific classification standards that take into account the privacy of those growth centers, will contribute
to put the proper methods to achieve desired objectives of its establishment in terms of quality and
quantity at all levels and sectors, in particular the residential suburbs due to its important role, adjacency
to cities, urban and social role, and the mutual influence between suburbs and cities.
The purpose of this research is to know the reality of the use of educational
techniques and laboratory devices in secondary vocational schools in Lattakia
Governorate, The research adopted descriptive analytical method through a questionnaire
con
sisting of (50) words distributed on four axes, has been verified the validity and
stability through appropriate statistical methods, And then applied to the study sample
which consisted of (127) teachers, assistant teachers and vocational teachers in a number of
vocational secondary schools in Lattakia Governorate during the second semester of the
academic year (2016-2017), The most important findings of the research:
-The degree of ownership of the competencies of the use of educational techniques
and laboratory devices in vocational schools and the degree of use of these techniques and
devices medium.
-The degree of obstacles to the use of educational techniques and laboratory devices
in vocational schools and the degree of requirements for the development of this use is
high.
- There were no statistically significant differences in the identification of the reality
of the use of educational techniques and lab equipment in secondary vocational schools in
Lattakia Governorate according to the variables of the place of study and the job title.
- There were statistically significant differences in the possession of competencies in
the use of educational techniques and laboratory devices in vocational schools and the use
of these techniques and devices according to the variable training courses for those who
followed one or more courses. There were no differences regarding the obstacles of using
educational techniques and laboratory equipment in vocational schools.
The research concluded with a set of proposals aimed at developing the use of
educational techniques and laboratory equipment in vocational secondary schools in
Lattakia Governorate.
This paper presents the Change vector analysis (CVA) approach for detecting and
characterizing radiometric change in multispectral remote sensing data sets
The dynamic changes of the land use/land cover were studied in lattakia city by
using two E
TM-Landsat-7 scenes, for the years 2000, and 2010, and the spatial resolution
of those two images was 15 m. The CVA algorithm has been applied and produced two
‘channels’ of output change information multispectral change magnitude and change
vector direction in land use/land cover during this period. Two models have been built
within ERDAS Imagine 8.6 software to perform the algorithm and evaluate the positive
and negative changes and analyze the the human impacts on the land use/ land cover
change.
This method can be applied to various fields of study in order to generate maps
represent the continuous development of land use and land cover. These maps can be
significantly useful for the regional and urban planning and natural resource management,
in light of the great expansion of urban areas at the expense of green spaces and
uncontrolled use of the land.
