This study includes a full analysis of climatic, vegetation, and topographical factors in Nabe Matta preserve (Drekish Region – Tartous Governorate – Syria), which is considered as the most important factors affecting forest fires. The data were coll ected for each fire and analyzed by statistical programs (SPSS) and (EXCEL), and the relationship between these multiple factors and the phenomenon of recurrence of fire in one area (fire risk region) was studied. Then the data and the results of the analysis and multi relationship had been studied within the geographic information system software (GIS) to obtain the map of fire risk region, as well as results from topographic maps (1:50.000), aerial photographs (1:25.000), and the needed maps were designed for the study such as (slope map - aspect map - vegetation cover map - infrastructure map - fire risk region map),then places of monitoring towers and centers of rapid intervention in high-risk areas have been proposed for the occurrence of fires. These maps are considered as warning systems and with it we can predict the probability of any fire in the Preserve when the appropriate conditions are provided for it.
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.
