The study aims to identify the most important geomorphological touristic sites in Dreikesh and explain their formation factors and characteristics using GIS, in addition, it analyzes the relationship between geomorphology and tourism by estimating the potential for each site according to several criteria, the results indicated the diversity of geomorphological features in the study area, including mountains, river valleys, caves, and volcanic necks, where the geomorphosite formed 24 sites, most of which met the criteria for natural tourism by 62% of the overall assessment results for the sites.

Our study was based on growth classes, so 25 trees were chosen, and two borers were taken from each tree in two directions (north, south).We put the samples in grooves on wooden rulers to be dried. Tree-ring widths were measured under a microscope to the nearest 0.01 mm. The correlation between rings width and (annual, seasonal) precipitation was studied for the period (1968-2007). In conclusion, we found out positive correlation values. Spring precipitation was the important; the 2007 ring was the narrowest, while the 1972 ring was the widest one. The largest effect was by (November, December, and April) rainfall.

In order to study the relationship between tree rings width of brutia pine and both of precipitation and temperature in three sites in Tartous, 10 dominant trees were selected in each site. Using increment drill two perpendicular samples from each tree at breast height were taken. The samples were treated, and well cross dated, then the rings width were measured to the nearest 0.01 mm. The tree rings time series were standardized to avoid the influence of age and forest management. Response functions method was used to test the relationship between climate and tree ringwidth. Results showed that, at low site Amreet, tree-ring width was more influenced by precipitation than temperature, especially in growing season and prior to it. At high site Kadmous, precipitation has significant effect between the end of spring and the beginning of summer (May and June), However, there was an obvious positive influence of April temperature (mean, max and min) on tree-ring width. At Tallah, tree-ring width did not significantly response to monthly precipitation, and showed negative influence by the mean and maximum temperature for July.
