Geographical Analysis of the Mos Important Geographical Factors Affecting Palm Production in the Kingdom of Saudi Arabia 1975-2015

Abstract

This study was aimed generally at geographical analysis of the most important geographical factors affecting palm production in Saudi Arabia. The researcher believes that certain geographical factors, namely population, heat, rain, humidity, average salinity and suitability of the soil, directly affect the production of dates. The study discusses these factors and  their impact on the production of dates crop in Saudi Arabia for the period 1975-2015.

To achieve the objectives of the study, the researcher used the analytical method through the GIS tool, which was used in the analysis of spatial statistical analysis (spatial statistics tools), and geostatic analysis provided by arc GIS Desktop tools to study the correlations between variables, The researcher also analyzed the study data in this curriculum using the Social Science Statistical Packages Program (SPSS), which is the repetitive distribution, percentages, and graphics, graphs and arithmetic average of the study variables. The most important results of the study were the study proved that there is a direct positive correlation between the kingdom's date production variables and the average summer temperatures for the period 1975-2015. According to spatial analysis, the average soil salinity in Saudi Arabia was 5.19 millimes/ cm, or about 5,190 ppm. All dates production areas in the Kingdom are located within the area with safe palm growing soils located between (1500 6000) ppm, except for Mzedina, which increased slightly by only 6062.31 pmm 0.66 per cent. The study concluded with several recommendations, the most important of which was Cooperation between relevant government authorities for reclamation of reclaimable soils that can contribute to raising date production to about. 500%
