Identifying and Explaining Multiple Functional and Non-Functional Factors in the Field of Sustainable Development of Rural Tourism (Case Study: Villages of Sarein City)

Sustainable development of rural tourism as a multifaceted and very important phenomenon. Today, most of the countries are trying to use the capacity and potential of rural areas to create sustainable development of rural tourism. But this category has different contexts and approaches and different factors play a role in it. The main goal of the current research is to identify and explain multiple functional and non-functional factors in the field of sustainable development of rural tourism in the villages of Sarein city, which has been investigated using a mixed method. The approach used in this research is a partially mixed sequential dominant status design, which takes place in two qualitative-qualitative phases. In the first phase, using the scope review qualitative method, relevant indicators have been identified and counted from related researches, and in the second phase, using the Delphi qualitative method, multiple functional and non-functional roles in the field of sustainable development of rural tourism have been explained from the perspective of experts have became. According to the findings of the research, in the first phase, 17 related internal and external researches were identified and their confirmation indicators were extracted by using the scope method. In the second phase, by holding three consecutive Delphi rounds, 12 experts categorized functional and non-functional indicators into six components and 81 indicators. According to the results of the present research, the sustainable development of rural tourism in Sarein city is due to various causes and factors, each of which has multiple impacts and impressions. Rural tourism, as a huge and rich potential in various fields, has a developmental and reconstructive role in the villages of Sarein city, and paying attention to its functional components can bring all-round rural development and progress and adopting measures for management and Control of non-functional components also prevent other harms and threats.

Introduction
One of the most popular types of tourism today, which includes a combination of effective factors, is rural tourism, which has developed significantly in recent decades. Today, rural tourism has adopted new trends and plays an important role in the sustainable development of rural tourism communities. Rural areas are important for the development of tourism because they are ecologically attractive areas that, in addition to nature, have a rich traditional culture that is very attractive. Therefore, adopting rural tourism as an alternative development approach has become a preferred strategy in an effort to balance economic, social, cultural and environmental regeneration and sustainable development. Therefore, most thinkers; Rural tourism has been considered as an opportunity to promote local development, which represents a set of activities that cause change in rural areas. Although many researches have paid attention to the positive and negative factors affecting the sustainable development of rural tourism, a research that can examine both cases together has not been done so far, and paying attention to these two important factors as the main focus. This is research. On the other hand, even though various researches have proposed components and variables in this field, there is still a lack of findings that can explain this dual role well, and from this point of view, this subject area has a lack of theoretical foundations. be On the other hand, it can be seen that some related researches in this field often take an incomplete path that do not lead to the presentation of conclusive results or findings, for this reason, in this study, the identification and explanation of multiple functional and non-functional factors in The field of sustainable development of rural tourism is focused, which means that first these factors are identified and then we explain the dimensions and aspects that include them from the perspective of experts. The keyword "multiple" has been used to describe these factors in two ways, one is related to the fact that these factors have different dimensions and aspects that must be identified, and the second is that these factors can be in addition to the impact and impressions related to themselves include other consequences and this category adds to their complexity and multidimensionality. In the following, theoretical foundations and research background, research methodology, research findings, discussion and conclusions are presented.
Objectives
Rural tourism has been considered as an opportunity to promote local development, which represents a set of activities that cause change in rural areas. In other words, rural tourism provides an opportunity for regional economic, socio-cultural and environmental sustainability, which brings multiple demands. Following this change in tourism demand, rural areas are no longer limited to the production of goods and agricultural products, but they are rich places with high potential to stimulate new socio-economic activities and reduce public problems etc are seen Therefore, the main goal of the research is to identify and explain multiple functional and non-functional factors in the field of sustainable development of rural tourism.
Methods
The current research is applied in terms of purpose and hybrid in nature. The method used is mixed, and the approach used in it is a partially mixed sequential dominant status design, which takes place in two qualitative-qualitative phases. In the first phase, using the scope review qualitative method, relevant indicators have been identified and counted from related researches, and in the second phase, using the Delphi qualitative method, multiple functional and non-functional roles in the field of sustainable development of rural tourism have been explained from the perspective of experts have became. In the first phase, where the scope review method was used, related indicators were identified and counted through various studies in this field. In the second phase of the research, which used the Delphi qualitative method, the researcher provides the items extracted from the previous phase to relevant experts to express their opinions regarding multiple functional and non-functional indicators in the field of sustainable development of rural tourism. In this phase, 12 experts were selected using targeted sampling, who were well acquainted with Sarein city. Their main expertise is in the field of tourism...
