Abstract
The problem of the study included a change in vegetation cover during a certain period of time if the study focused on knowing the reasons that led to the change of vegetation cover during the period 1999-2020). In addition to keeping pace with scientific progress and the flow of digital data from satellite images, the vegetation status index (NDVI), the infrared vegetation cover index (IPVI), the drought index and the rain coefficient were employed to study the status of vegetation cover. The study also relied on climatic data for the period 1999 - 2020) in the station of the study area and agricultural (plant) data (1999 - 2020) and according to the administrative units. The study showed a satellite visual analysis of vegetation cover a clear decline in the area of vegetation cover in the study area, especially in 2020, it amounted to about (54403) dunums, at a rate of (42%), where the area of vegetation cover was greater in 1999, as the area of vegetation cover occupied about 77652 dunums And at a rate of (59)%), the category that is (greater than 0.8 to +1) increased in value in 1999, amounting to(22723), while it reached its lowest level in the year (2020) amounting to (4000) dunums, which means that the index of vegetation or plant biomass (ndvi) is increasing in the period 1999) and this indicates that the plant density is high, while this millennium decreased in In the year (2020), the results of the study showed through the use of modern technologies and the application of vegetation density indicators in a clear change and decrease in the study area. The climate is very ( ) dry in it, as well as through the application of the monthly and annual results of the ang equation that the study area falls within the very dry climate dry in it, as well as through the application of the monthly and annual results of the ang equation that the study area falls within the very dry climate.
