مدلسازی و آنالیز چیدمان فضای ژئو-دموگرافیک در حوضه آبریز خلیج فارس

Introduction
Space-syntax analytical approach is related to the space phenomenology and some space structural arrangements including, textures, patterns, ratios and relations. In Iran military doctrine, defensive strategies had bolded more than space syntax patterns and interceptions in the scope of residential area development. Therefore, recognition of space structure, can be a foundation for territorial perception and basic land use planning and then affecting cognitive scope of the other sciences, causing to enrich it. In this study, with respecting to the space-syntax approach, geo-demographic space, conceptualized, modeled and formulated in a hierarchical structure including spatial syntax, array and element. First, spatial syntax structure had descripted and interpreted using concepts such as spatial relationships, patterns and ratios. Then, spatial relationships acting between in situ and demographic arrays, had conceptualized and modeled. These modeling had performed in the conceptual, mathematical(numerical) and graphical stage, respectively. the models, resulted in spatio-graphs with fractal and non-fractal structures to represent relationship depth and intensity inside spatial components. Cumulative, distance-based, scattering and distributional arrays, were considered in the scope of spatial patterns syntax. Conceptual models prepared and developed using quantitative and mathematical models. Spatial ratios had also interpreted with allometric-isometric concepts and then combined with hypothetical concepts of space syntax to form conceptual and quantitative models. The recent research main goal is to follow residential space perceptions, using space syntax recognition components related to the demographic elements in order to be used in the basic land use planning, passive defense, behavioral management and territorial space security.
In order to achieve the research objectives, the following process was designed:
Step 1: Determine and identify the space of the study area and understand the problem.
Step 2: Study document resources
Step 3: Prepare database.
Step 4: Spatial Join
Step 5: Select space elements to analyze geo-demographic space syntax
At first, the demographic parameters were extracted from the statistical data of Iranian Center of Statistics and the most comprehensive list of cities in Iran separated based on the provinces, cities and villages in the study area, and the location and population were determined. In the following, the geomorphic and climate parameters were selected by regarding the geodemographic space of the study area. Data collection from information sources was divided into four raster data, vector data, climate data, and software database categories and then, the data were assessed.
Methodology
Relying on the theory, space syntax and phenomenological approach, this research analyzes the spatial layout of settlements. It tries to discover the logic of space syntax in the northern coast of Persian Gulf by presenting some concepts such as spatial relationships, spatial patterns and configuration, and spatial ratios as the elements of spatial analysis in the layout of settlements.
Results and discussion
In this research, the fundamental concepts such as spatial relationships, spatial patterns, and spatial ratios are considered as the elements of spatial analysis in the layout of settlements in relation to the environmental components.
For modeling the spatial relationships among the four modes of relationship between the elements, two modes were considered: one to many, and many to many. Accordingly, each mode took the form of a conceptual model in a hierarchical and multilevel (fractal) or single-level (non-fractal) manner for the land of Iran and the coastal provinces of the Persian Gulf. Then, they were formulated and finally, displayed in the graphical form. Also, the correlation matrix of demographic and geomorphic components was generated and all the relationships were individually used for the pairwise comparison. As a result, the parameters with stronger relationship were identified.
For analyzing the spatial patterns, the analysis of frequency distribution of geomorphic parameters such as height, slope, geomorphic units, drainage basins, distance from the coast, distance from the peaks, distance from the streams, density of peaks, density of streams, climate parameters of temperature and precipitation, and latitude and longitude as two spatial dimensions, and the demographic parameters such as the density of urban and rural populations and the density of urban and rural points was performed. For generating the spatial models, analysis of the geographical distribution measurement, a set of statistical-spatial analyses including the central feature, mean center, median center, standard distance, and directional distribution analyses were performed using the geographic information system on the urban population of the study area, and their location was determined.
Finally, the ratio of geomorphic and demographic components was analyzed by expressing the spatial allometric-isometric concept in the layout of settlement space and the components with higher allometric and isometric ratios were selected and classified according to the numerical correlation ratio as strong, moderate and weak.
Conclusion
In this research, relying on several epistemic fields which are considered an innovative approach, the conceptual models such as fractal and non-fractal spatial relationships, spatio-graph, and allometric-isometric spatial ratios were presented and transformed to quantitative, mathematical and graphical models to maintain the relationship between the theoretical and epistemic foundations with the quantitative and mathematical modeling.
In this research, with the emphasis on the approach to space syntax and phenomenology, allometry, post-hunters, and geospatial theories, the geodemographic space of the Gulf catchment area is analyzed and conceptualized, and in all parts conceptual modeling is applied to modeling Numerical, mathematical and quantitative numerals have been driven to maintain the relationship between theoretical and epistemic foundations with quantitative and mathematical modeling. Therefore, based on a number of epistemological fields which are innovative in their own way, models such as fractal and non-fractal spatial relationships, space science, alometric-isometric ratios are presented. The results of this research show that the recognition of the structure of space and the formulation of habitation alternatives can be the basis of cognition and territorial perception and fundamental harmony, and the art and skill of discovering the logic of space syntax allow us to do this. We can provide the desired layout space.
