الملخص
يهدف البحث الى إعطاء صورة مفصلة عن واقع التوزيع المكاني لخدمات قاعات المناسبات وتحديد درجة ملائمتها المكانية خدمة لسكان ومساحة الاحياء السكنية في مدينة سامراء لعام 2020 ، باستخدام الأسلوب التطبيقي المعاصر الذي اعتمد تطبيق تقنية نظم المعلومات الجغرافية (GIS)، باستخدام العديد من وظائفها في عملية التحليل المكاني وبناء نماذج الملائمة المكانية وفق المعايير التخطيطية، وقد توصلت الدارسة الى وجود قصور وخلل واضحين في التوزيع المكاني لخدمات قاعات المناسبات في المدينة، مما جعلها تتخذ النمط العشوائي المتقارب ، إذ بلغت قيمة (R) المحسوبة (0.75)، مما يؤدي الى ضعف الخدمة المقدمة ، وان ما نسبته (68.49%) من إجمالي مساحة المدينة فقط مخدومة بنطاق تأثير خدمات قاعات المناسبات مما يشير إلى حجم النقص الحاصل في التغطية المثالية لهذا النوع من الخدمات والحاجة الى بناء نماذج الملائمة المكانية المثلى لتوزيعها.

- Geographers are interested in studying the spatial distributions of geographical phenomena by identifying the spatial center of gravity or the geographical center of the focus or the main point of attraction for those distributions and comparing it to the realistic distribution within a specific spatial framework (region, region, city) Source: - Muhammad Azhar Al-Sammak, Ali Abbas Al-Azzawi, Research Geographical Between Specific Methodology, Quantitative Methods and Contemporary Information Technologies (GIS), Ibn Al-Atheer House for Printing and Publishing, University of Mosul, 2009, p. 121
- It is represented graphically on the map by drawing a circle whose center is the spatial mean and the radius of the standard dimension, and to know the extent of dispersion, it is possible to take advantage of the probabilities of the moderate distribution to show the concentration of (68.27%) of the elements of the phenomenon around the spatial center.

- The distribution trend scale is used to determine the shape and direction of the geographical extension of the spatial distribution of services within the area of the studied area, and to make use of it for planning procedures Source: - Ali Abd Al-Abbas Al-Azzawi, Statistical spatial analysis using Arc GIS 9.3, University of Mosul, College of Education, Department of Geography, 2011 , P. 720 .
- It is used to measure the dispersion of points around each other and to determine the general pattern of the spread of points in spatial distributions, as these distributions can be random, regular, or focused according to the value of the analysis (R).

- This analysis is used to find out the area covered by each service, regardless of its schematic level and spatial hierarchy, by converting it from the point layer to the polygon layer, so that for each spatial location there is one polygon that shows its actual services (not The scope of its effect) This method demonstrates the ability of numbers of health centers to absorb the population in the place through the gradation of colors in measuring efficiency, as dark colors indicate a mismatch between health centers and the area they cover with their services, while light-colored areas indicate the areas in which they are The area is less than the capacity of health centers to cover.

- Finding the best places for a particular service based on known criteria is called the suitability model, which is an abstraction of the truth that allows the possibility of studying spatial relationships, and is used in geographic information systems to link classes with logical processes to help in decision-making.
