تقع منطقة الدراسة في الجزء الشرقي من البادية السورية بين محافظتي دير الزور وحمـص حيـث 2 تمتد من منطقة كباجب حتى سهول قصر الحير الشرقي، وتبلغ مساحة المنطقـة المدروسـة 1485كـم . أخذت عينات من الطبقة السطحية للتربة و ذلك كل 4 كم و اختير نظرا ً لتجانس التضاريس و الغطاء النباتي و غطاء التربة، 48 عينة سطحية بهدف التنبؤ بمحتوى التربة من كربونات الكالسيوم مـن خـلال صـور الأقمار الصناعية لاند سات 7 TM E . لقد سجلت الانعكاسات الطيفية لعينات التربة الـسطحية مخبريـاً باستخدام السبكتروراديومتر نوع Pro Sepec Field ، و أظهرت النتائج أن وجود كربونـات الكالـسيوم بنسب عالية في التربة يزيد من قيم الانعكاسية الطيفية، و أن المجال الطيفي 1B TM هو الأفضل للتنبـؤ بمحتوى التربة من كربونات الكالسيوم.
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.

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.
In this study, drought in the eastern region of Syria (Hasake, Rakka,
DerAzzor, Bokmal & Kameshli) has been investigated using SPI, NDVI
indices.
We used a set of data containing precipitation data for period from 1975 to 2010 to calculate Standardized Precipitation Index SPI, and MODIS time series images in April for period from 2000 to 2010 to calculate the Normalized Difference Vegetation Index NDVI.
Optimum Index Factor (OIF) technique of statical analysis is fusion with Decision Tree Classification (DTC) method in determine the spectral critical value for separation the features in the image processing programs, and the architecture of this app
roach is designed for accuracy extracting the area and distribution urban from space image. Accuracy assessment of that approach is tested by comparing the supervised classification results for these feature from both the original bands of image and synthetical bands/indices of the image upon OIF value. Applied results of the approach on certain district represent the north Swaidaa city by Quick Bird image are: 98% for the suggested approach opposite 93% for supervised classification method of the synthetical bands image and 82% for original bands image. Accuracy of the approach is derived from exact separation the urban feature than similar spectrally objects in the image as basalt exposures and roads, where achievement of the other processing methods are less.
The basic step in this algori thm is determining the number of clusters
(K) then calculating the distance between each cluster
center and the elements of images to join each element
to the closest cluster depending on threshold distance.
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.
