مخاطر تدهور الغطاء النباتى باستخدام تقنية الاستشعار عن بعد و نظم المعلومات الجغرافية : دراسة حالة منطقة العيلفون شرق النيل-الخرطوم في الفترة من 1972-2020 م

الملخص EN

The natural vegetation cover in the east Nile region has subjected to severe and continuous to deterioration by human action, which result in various losses and spreads with many risks.

The paper aimed to study deterioration of vegetation detection of east Nile region by using remote sensing techniques, by application normalized differences vegetation index (NDVI) due to what techniques had from quickly, accuracy, and completely.

In addition to saving effort.

In order to identify the causes of the desecration of vegetation study area and the effect of decaying vegetation next to propose strategies for reduction of decaying vegetation study area.

The researchers employed the application of GIS remote sensing to analyze and monitor the greenness of plants, the plant and its evaluation for periods from 1972 to 2020 and the interpretation of the emergency change according to the environmental and human variables and the identification of the areas most affected.

By following the quantitative and inductive analysis approach with the aim of extracting vegetation cover and identifying changes through the application of vegetation cover indicators, using many program, the most important of which is (ArcGIS pro 2.5) using the Landsat satellite, the vegetation cover models were taken for very ten years for a period of 40 years in the period between (1972-2020) and you processed the satellite images taken for the study area by my program (Erdas.Gis pro) through the spectral and spatial optimization of satellite visuals, then analyzing them and calculation the areas of vegetation cover.

The study concluded that the change in the area of natural vegetation cover of the region witnessed a state of deterioration and expansion from time to time, and perhaps the reason is mainly due to the natural variables represented by the element of climate and the increasing human activity and the resulting.

The study concluded with some recommendation including dealing with the phenomenon as a priority in the environmental, social and economic fields, reconsidering the applicable procedures, activating the role of society and raising the level of environmental awareness.
