Abstract
Introduction
One of the main approaches to the physical-spatial development of metropolises is to use the maximum available capacities of the city and minimize its limitations by using all available resources of the city. This approach requires planning in the form of intermittent development, and non-use of resources and lands outside the city, if there are internal resources and uses, including brown and unused lands, and especially polluting. The importance of endogenous urban development for the management and reuse of brown lands is such that the abandonment of these lands will greatly cause damage to local communities and inefficient physical spatial management of the city in the future. On the other hand, these lands, due to their characteristics, are polluting and causing environmental damage to a large extent, threatening the health of local communities. However, achieving a scientific and operational mechanism is very important in providing a suitable model for mid-term development based on the optimal management of brown lands. The metropolis of Tabriz, as a trans-regional city, is facing several physical-spatial challenges in the field of interstitial development and optimal management of brown lands. Therefore, maintaining coherent and desirable patterns of urban development in order to manage lands incompatible with urban function is one of the main problems of land use management and endogenous development of this city. This study seeks to explain and analyze the opportunities that can be developed within the city by using the components of interdependent development and brown land management approaches of the present study. Therefore, a preliminary review of the research literature in this field shows that the activity that seeks to provide the desired model of intermediate development in the form of grounded theory has not been presented so far and the studies are general approaches, and only preliminary explanations of Indicators and effective factors in development have been intermittent. Therefore, the purpose of this paper is to explain mesenteric development by adopting an approach based on data foundation theory in the field of brown land management. Therefore, the main question of the research is, what is the optimal model of mid-term development based on the components of brown land management in the metropolis of Tabriz?
Methodology
The present research is applied in terms of purpose and descriptive-analytical in nature. Data were collected by library and field studies based on an expert questionnaire. The statistical population of the study includes the residents of Tabriz, but due to the specialization of the subject, the statistical population of experts using the Delphi method has been used to distribute the questionnaire. The method of sampling snowballs is 30 people. For data analysis, one-sample t-test and path analysis in the form of DPSIR model with the help of SPSS software were used.
Results and Discussions
The results of quantitative and field studies showed that the population dynamics component with a factor of 0.26 has a very small role in intermediate development. In contrast, urban planning and legal criteria with a coefficient of 5.42 have a significant impact on this issue and for the optimal management of brown lands and achieving the desired pattern of intermediate development, special emphasis should be placed on this concept and criterion. In addition, the analysis of indicators in the form of DPSIR model showed that the "response" component with a coefficient of 3.3 received the highest score. Therefore, according to the group of experts in the statistical community, for the development of the desired intermediate in the metropolis of Tabriz, special emphasis should be placed on the response forces (such as: security; pollution; environmental health; urban space formation). Because, these factors can provide more operational models and strategies to organize and exit the current trend. In contrast, the impact component with a coefficient of 2.73 received the lowest score. On the other hand, the study of components with path analysis test showed that the "pressure" index with a total effect coefficient of 0.623 has the greatest impact and causal relationship with the favorable pattern of interstitial development and brown land management. On the other hand, the "response" components with a total effect factor of 0.591; "Impact" with a total effect factor of 0.556; "Status" with a total effect factor of 0.547; And "driving force" with a total effect factor of 0.537.
Conclusion
Finally, according to the obtained results, in order to achieve the optimal and desirable pattern of intergenerational development and management of brown lands, it is necessary to observe the following:
Development of tax rules and mechanisms for brown and polluting lands in order to oblige owners of brown lands to change the required land uses of the city
Organizing the city structure and using the land use capacities and improving the access distance
Transfer of non-urban uses such as military barracks, and change of use of agricultural lands to green space and parks and change of industrial uses to required general uses
Regulating the urban road network and increasing the capacity of the road network, especially in the central urban context in order to increase access and reduce traffic
Strengthen the quality of housing by monitoring construction and providing facilities to citizens
Upgrading environmental capacity to rejuvenate the living space away from any pollution
