Cities are more dynamic when the smart growth of the city takes into account the well-being of human life in various directions; Therefore, by considering man as the axis of urban development, the importance of his quality of life stands out more. In fact, one of the main goals of urban planning is to achieve a quality urban living environment, which is possible through the implementation of smart growth indicators. The main goal of this research is to investigate the impact of smart growth on the quality of life of the residents of District 8 of Mashhad Municipality. The research method is descriptive-analytical using library sources and survey data (questionnaire). Also, using Cochran's formula, a statistical sample consisting of 382 residents of District 8 of Mashhad city has been studied.The collected data were checked through one-sample T-test and Spearman's correlation coefficient was used to analyze the effectiveness. For illustration, the results of the research using the IDW method are displayed on the maps, and the results show the favorable situation of the 8th region in terms of smart growth indicators with an average of 3.19 and quality of life with an average of 3.31. Also, there is a significant relationship between these two variables with a correlation coefficient of 0.311, which indicates the positive impact of smart growth on the quality of life; In other words, in neighborhoods that have favorable conditions in terms of smart growth indicators, residents are more satisfied with the quality of life in those neighborhoods
Extended Abstract
Introduction
The excessive concentration of the population and the increase of interactions and activities in the cities have caused an increase in environmental problems, pressure on the urban environment, an increase in class differences and injustice in the access of different social groups to resources and facilities, and finally, in addition to construction without Unprincipled planning has also transformed the spatial construction of the city. Therefore, the necessity of creating a model of smart growth was considered by urban managers and planners, so that by using the solutions of this model, a step can be taken in the direction of reducing scattered urban growth and increasing the quality of urban life. Paying attention to the physical environment of the city by managers and planners, as well as organizing it, plays an important role in improving the quality of human life. In Iran, from the 1340s onwards, the population of cities grew due to high natural growth and migrations from villages to cities, and the urban body expanded based on the land market. On this basis and considering the lack of control in the overall development of Iranian cities, this problem has become more apparent and always requires the evaluation of urban development plans. Therefore, in this research, the main goal is to investigate the impact of smart growth indicators on the quality of life in the 8th district of Mashhad and to what extent it has helped to improve the quality of life of the residents of the region in terms of physicality. It should be noted that in order to achieve the main goal, the following goals have been considered:

Investigating the status of smart growth indicators (compression and access) in region 8
Investigating the quality of life in region 8

 
Methodology
The current research has a practical purpose and according to the means of achieving these goals, it is descriptive / analytical based on documentary library studies and field survey. Cochran's formula was used to determine the appropriate sample size (statistical population). The statistical population of this research is residents of District 8 of Mashhad Municipality. In order to check the validity of the questionnaire, it was used from the point of view of urban planning professors, and for the reliability of the questionnaire, reliability was calculated using Cronbach's alpha. In order to analyze the collected data, one-sample T-test was used in spss software and Spearman's correlation coefficient was used to determine the effect of intelligent growth indicators on quality of life. Then, in order to visualize the results, the data is entered into the GIS software and the results are displayed on the map using the IDW method.
 
Results and discussion
The main goal of this article is to analyze the impact of smart growth on the quality of life of the residents of District 8 of Mashhad Municipality. The results show that both intelligent growth and quality of life variables have a good condition in the region with averages of 3/19 and 3/31, respectively, and in total, the significant correlation between intelligent growth and quality of life in the region is 8 with a correlation coefficient of 3/11 shows; That is, as much as smart growth is more favorable in a region, the level of quality of life will also increase under its influence. The reverse of this correlation is also true. By examining the research records related to intelligent growth and quality of life, we reach an important point:
Note: Although the findings of this research in the field of intelligent growth are in line with the findings of studies such as Zarrabi et al, Raeisi & Kiani and Rahnama & hayati; Because we find out that it can be done by increasing building density, population density, reducing car travel and increasing pedestrian routes. Achieved intelligent growth algorithm in different areas. And also, on the other hand, the findings of this research are in line with the research conducted in the field of quality of life, including the work of Fethalian and Partovi., Wiziak Bialuska and Ahdenjad et al;Because the results of recent research show that in order to have a good quality of life, factors such as the existence of a quality public transportation system, a quality communication network, quality housing, quality leisure spaces and welfare are necessary. In this article, the author has tried to evaluate the effect of both variables on each other as a combination (that is, the effects of intelligent growth on the quality of life). The only similar studies in this direction are by Khoshghadam and Razzaghi Asl and Zanganeh et al. None of them have addressed "the effects of smart growth on the quality of life, focusing on the two indicators of compactness and accessibility" as stated
 
Conclusion
The results of this research show that there is a significant relationship between smart growth and quality of life in District 8 of Mashhad Municipality. Therefore, it can be said that smart growth indicators play a significant role in improving the quality of life; because they have been able to prevent the nobles of the neighbors from entering the buildings by creating compact and vertical uses and walkable and transport-oriented areas and to create uses that are compatible with the surrounding environment and suitable conditions in terms of access to services, main street networks and smooth traffic achieve. Therefore, compactness, building density in area 8 has helped to create open space for effective use of land and resources and has created a higher quality residential environment. Also, proper access and development based on public transportation, pedestrian-oriented and the existence of multiple routes to access different points, while solving the problems of traffic congestion, saving the cost and commuting time of the residents and easy and quick access to the main and high-quality roads. has helped.
