Process model of landscape quality of Tehran urban green space using interpretive structure model (ISM)

The issue of quality crisis in the current situation is one of the major challenges of cities and hence one of the main concerns of decision makers, implementers and users of urban environments. Architects and urban planners believe that the environment urban landscape, although attempted to play an important role in improving urban quality, does not have the appropriate approach to respond to this issue. It seems that considering the concept of landscape, which is a visual and intellectual, the appropriate approach to respond to the needs of this issue should be accompanied by a model of both. from an landscape architectural point of view, it is important to review the development process and the need of paying attention to both visual and intellectual aspects of the phenomenon in order to preserve its natural organs. The purpose of this study is to provide a coherent theoretical framework to explain the concept of landscape quality and its components using the mental model of native landscape experts of Tehran, because the green space of this city has different qualities in each region and does not follow a specific quality pattern to meet the needs of citizens. Each of the experts in this field has pointed to one of the dimensions of the process, but a comprehensive model of the dimensions has not been presented. This study is a qualitative research that has been done using the grounded theory method. In this research, first, by studying the literature, the dimension of the process are identified and in the next step, using the data interview method of the foundation, the initial codes are extracted. In the next step, the indicators extracted from the literature are integrated with the concepts obtained from the interview and using a new analytical methodology called interpretive structural modeling (ISM), the relationships between the dimensions and quality indicators of the desired space are determined and integration is analyzed. The result has led to the design of "urban landscape quality model". The research results show that the integrated landscape quality model includes six levels, which these dimensions interact with each other.
