هدف البحث إلى دراسة تغيرات الغطاء النباتي لمحافظة اللاذقية باستخدام تقنيات الاستشعار عن بعد و ذلك من خلال تطبيق قرينة التغيرات النباتية، لما تتميز به هذه التقانات من سرعة و دقة و شمولية إضافة إلى توفير الجهد و المال. حيث أظهرت طرق كشف التغير و تطبيقها على صور Sentinel2 حالة النبات و مساحة انتشاره في منطقة الدراسة. إضافة إلى معرفة تغير الغطاء النباتي مع مرور الزمن و وضع قواعد بيانات تفيد في معرفة حالة النبات و المراقبة الدورية لتغيراته. حيث تمت دراسة التغيرات المرحلية السنوية و الشهرية للغطاء النباتي في محافظة اللاذقية من خلال كشف تغيرات الغطاء النباتي لشهر آذار بين العامين (2016-2017م)، ثم كشف تغيرات الغطاء الشهرية بين شهر آذار و آب لعام 2017م. و لوحظ عدم وجود تغير كبير سواء تطور أو تراجع للغطاء النباتي عند دراسة التغيرات السنوية. بينما لوحظ تراجع كبير للغطاء النباتي في المناطق السهلية الغربية من المحافظة عند دراسة التغيرات الشهرية بين آذار و آب و ذلك بسبب ارتفاع درجات الحرارة. و تطور كبير للغطاء النباتي في المناطق المرتفعة.
The research aimed to study vegetation change detection of Lattakia province by using remote sensing techniques, By applicating Normalized Differences Vegetation Index (NDVI) due to what these techniques had from quickly, accuracy, and completely. In addition to saving efforts and money. that change detection methods have showed by applicating it on Sentinel2 images the plant situation, it's area and distribution in the studied area. In addition to knowing plant's cover changes through time passing. Putting geo databases which benefit in knowing plant situation, and the periodicity supervision for it's changes. The yearly and monthly changes of vegetation cover have been studied in Lattakia province, By making change detection for plants cover of march between (2016-2017). Then making change detection between march and august of 2017. It was observed that there were no big changes, Whether increasing or decreasing for plants cover when studying the yearly changes. While there was big decreasing of plants cover at western plain areas of province when studying the monthly changes between march and august due to raising of temperatures. And big increasing of vegetation in high areas.

Studying of land use changing Detection needs to the speed of implementation to
convoy the changes on the ground. the traditional ways in the analysis and visual
interpretation of the images and field studying need a lot of time and effort. So The
objective of this search is to classify group images (Landsat TM , ETM+) taken in different
dates automatically, and then to calculate the area of each land use/land cover, during the
years studied (1990 -2000- 2010) and comparison areas to identify the most important
changes occurring during that period.
The risk of soil erosion is the most important problem and challenges facing the agricultural process in the Syrian coast at the present time, especially in the areas surrounding rivers and water bodies.
This study aims to show the land use changes during the period 1970 – 1991.
The study includes the city of Homs and the surrounding areas, with total
surface area of 9686 ha. To carry out this study, aerial photographs were used
where sets of diff
erent periods were taken, one was taken in 1970 with a scale of
1/20000, and the other set for the year 1991 with a scale of 1/15000, the two sets
of aerial photographs were interpreted and analyzed after the delineation of the
targets, and two maps were prepared after unifying the scales and selecting the
proper legend.
The results indicated obvious changes in land use, for example, the area of
cereals crops was in 1970 about 32.9 % of the total area and decreased by 11.8
% in 1991. In the area of gardens a reasonable increase was recorded, while in
the area of vineyards an increase of about 1 % was noticed.
But the big issue is the urban expansion at the expense of arable lands, the
expansion area of housing has been increased from 8% in 1970 to 24% in 1991,
and the area of civil establishments was increased from 2.27 % in 1970 to 5.47
% in 1991, in the new concept of desertification urban expansion at the
agricultural land means a permanent desertification, this matter should be
considered seriously and the necessary measurements must be taken into
account.
The aim of this research was to investigate the changes of vegetation and
regeneration of plant species in Kassab forests after 1991 fire. The study area is
located in the North western part of Syria in the middle of Al-Baier and Al-
Bassit forest
s to the North of Latakia. Thirty five plant surveys (Relevé) were
carried out in the study area during 2009 according to Braun-Blanquet method
included the burned area and the nearby locations of non-burned forest. By
comparing the plant surveys (Relevé), results showed good regeneration of
most plant species that were in the study area before the fire. Three forms of
vegetation were distinguished in the study area: 1 - The areas where dominance
is shared between Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris
(Boiss.) Chalabi. 2 - Areas dominated by Pinus brutia Ten. with accompanying
species from Eu-Mediterranean zone and supra Mediterranean zone. 3 – Areas
where Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris (Boiss.)
Chalabi are partly or completely absent, and dominated by shrubs and grass
species.
The study area (1485 km2) is located in the eastern part of the Syrian Desert
between the provinces of Deir al-Zour and Homs. Stretching from Kabbajeb to
Heer Palace. Due to the similarity of topography, vegetation and land cover, 48
samples were
collected one sample each 4 KM in order to predict the content of
the soil of calcium carbonate through satellite images Land Sat ETM7. The
spectral reflections of surface soil samples were recorded at laboratory using
spectroradiometer (FeildSpecPro®). The results of this study showed that the
presence of calcium carbonate at high rates in the soil increases the spectral
reflectivity values, and that the spectral domain TM 1B was the best to predict
the content of calcium carbonate in the soil.
