This piece of research analyzes the general-index change of annual medium temperatures in some stations of the Syrian Coast during the years 1970-2010, so as to identify the amount of change in temperatures and the effect of such a change on the prob
able density that results in annual medium temperatures that are both extreme and unnormal.
Results point to an increase in temperatures in all those stations between 0.8 and 2 Celsius degrees. This increase is significant statistically. At the same time, temperatures had not gone lower than their general average in all those stations during the first decade of the 21st century, contributing to an increase of the annual average of temperature during the years 2001-2010 in comparison with the years 1970-2000.
Using Natural Distribution Diagram during the years 2001-2010, analysis of the probable density of temperature refers to a great increase in the possibility of having higher extreme temperatures whose value did not exceed 5% over the last three decades. By contrast, lower extreme records had zero probability and got higher than they had been during the three decades of the late century.
تحليل الشبكات في أنظمة المعلومات الجغرافية ...
تمثل الشبكة مجموعة من الخطوط والنقاط التي تمثل الكائنات الجغرافية المتصلة مع بعضها البعض والتي من خلالها تتحرك الموارد (سيارات , مياه , كهرباء , غاز....الخ)
1- أنظمة تدفق موجهة
يتحرك التدفق من المصا
در إلى المصارف
الموارد لا تملك القدرة على اتخاذ قرارات المسير
(على سبيل المثال، نظام النهر)
2- أنظمة تدفق غير موجهة
النظام لا يتحكم بشكل كامل بعملية التدفق
الموارد تملك القدرة على اتخاذ قرارات المسير الخاصة بها
(على سبيل المثال، نظام السير)
يواجه الأمن المائي العربي تحديات كثيرة من أهمها النقص في موارد المياه
لأسباب طبيعية أولا و لصعوبات تلبية الاحتياجات المائية مع تزايد الطلب عليها ثانيًا، و لأن المياه أساس التنمية الاقتصادية (الزراعية و الصناعية)، و لا بد من تأمين الاحتياجات الأولية
الأساسية للسكان (البلدية)، و لأن 60 % من موارد المياه العربية الجارية تأتي من خارج الوطن العربي مما يشكل ضغطًا متعدد الأبعاد و الاتجاهات و المستويات على الحقوق المائية العربية، و لأن المياه تحتل مكانة مركزية في الجيوبولتيك الصهيوني، و هذا يشكل تحدٍيًا كبيرًا للأمن القومي العربي. حاول البحث دراسة واقع استثمار المياه في الوطن العربي فتبين أن 88 % من المياه المستخدمة تذهب إلى الزراعة، و أن 7% تذهب إلى الاستخدامات البلدية و نحو 5% إلى الصناعة.
و لكن بالوقت نفسه يستثمر نحو 53 % من موارد المياه المتاحة، و هذا يعد تجاوزًا خطيرًا للمستوى المسموح به عالميًا. قام البحث بوضع استراتيجية مناسبة لإدارة موارد المياه و إيجاد علاقة توافقية بين الاحتياجات و قدرات الإمداد بالمياه، من الزراعة و الاستخدامات البلدية و التنمية و الدفاع عن الحقوق العربية المائية و التصدي للأطماع الصهيونية في المياه العربية.
Wheat is the most cultivated strategic crop in Syria , it occupied first
rank of cultivated area , and second rank of production value , in addition
to that bread is the main nutrition in Syria .
The aim of present study is to recognize to sectori
al structure of
wheat production in Syria through studying the spatial concentration,
specialization, economic efficiency, and recognizing the dynamic
production of wheat during the study period to give a real picture about
this strategic crop .
The practical significance of this study is to give a real picture about
trends of wheat production, areas, yield, and to determine the level of
spatial concentration, specialization, and economic efficiency in every
governorate in Syria during studying period to show the impact of spatial
diversities on wheat production in Syria .
ركَّز موضوع الدراسة على بحث التحولات الديموغرافية و بيان أثرها في البطالة في الجمهورية العربية السورية. بين عامي 1960 و 2010 م. و قد حددت
الدراسة حجم السكان و تطوره الملفت للنظر، إِذ تضاعف 4,5 مرة خلال نصف القرن الماضي. أي بمعدل زيادة سنوية قدرها 50
0 ألف نسمة. كما بينت الدراسة أحد عناصر النمو السكاني المتمثل بالزيادة الطبيعية. و التحول النسبي في التراكيب العمرية للسكان، التي تؤثر في زيادة نسب كل من القوة البشرية، و القوة العاملة، و من ثم زيادة حجم المتقدمين لطلب العمل على عدد فرص العمل المقدمة لهم، مما يؤدي إلى رفع نسب البطالة. كما تناولت الدراسة البطالة و تطورها، و تراكيبها العمرية، و التعليمية، و النوعية و لاسيما بطالة المرأة. و الآثار الاجتماعية و الاقتصادية و السياسية للبطالة.
The study and evaluation of the circumstances and the factors that affect the
geography of the inhabitants services in terms of the needs of services, the use of
it and the spatial arrangement is considered one of the major trends in the
geographical studies of the sector of population services, and without it, the
geographical study of any of the geographical phenomena of services cannot be
complete.
The basin of Al-Kandeel Valley represents one of the basins of
western northern area's mountains in the Syrian Arab Republic which is
situated just like the axe in the eastern northern and western southern
direction covering approximately 155km2 w
ith a length rating 20km of
complicated geology character (Structurally & Constructively) where you
can find a variety of surface rocks among of which there are metamorphic
and sedimentary rocks that are of severe dislocation as being subject of
high construction potential imposed by the location of the area under the
aspect of thrust of the Arab plate under the Jurassic plate. Its height is
gradually rating clearly from the eastern northern to western southern.
The values of its local terrain rated between 5 m/km2 in its plain area at
the drain point and 375 m/km2 at the mountain eastern northern area. The
climate prevailing in this area is of seasonal rains and classified under the
Mediterranean Climate (Plain-Mountain).
The problem of this Research has been defined through the presence
of large tracts of agricultural land and the availability of trillions of
dollars invested outside the Arab world or in foreign banks and with the
importation of millions of tons o
f food each year and with billions of
dollars and Arab food security is an important part of Arab national
security and with the presence of 45% of the Arabs living in rural areas
and about 31% of the Arab labor force works in agriculture.
The irregular atmospheric situations that happened in Syria in the last
few years, caused unusual rainfalls that badly affected the environment
they appeared especially in the interior regions of Syria. They are called
the local rainfalls in speci
al regions, either in spring when it becomes hot,
or in autumn before it becomes cold. The unexpected rainfalls that
happened in May in 2007, were exceptional because it rained heavily for
along time.
This event is caused by many atmospheric factors and local reasons.
The results were great floods and inundation which caused losses in
properties and souls and that led to soil Erosion.
This study aimed to analyze the effect of the Jordanian landlords
and rented law in fulfilling the residential need for the inhabitants in al-
Manshia and shafa alamerieh in Al-salt city in particular and in Jordan in
general throught determining
and measuring the consent of the citizen
about the Jordanian landlord and rented law, which is one of the most
important laws that determined and organized the ownership and renting
the residential unit in Jordan .
