Abstract:
انسان ذاتاً موجودی کمالگرا است، بدیهی است این خصوصیت در زمینه محیطزندگی شهری نیز صدق کند. بشر همیشه به دنبال بالابردن کیفیتزندگی خود و زیستپذیر کردن آن میباشد. در چند دهه اخیر بروز بحرانهای مختلف در ابعاد اجتماعی، اقتصادی، زیستمحیطی و کالبدی که ناشی از برنامهریزیهای نامناسب در سطح شهرها است منجر به تنزل کیفیتزندگی و پایین آمدن سطح زیستپذیری مخصوصاً در شهرهای کوچک شده است. بهبود کیفیتزندگی در جوامع شهری هدف غایی برنامههای شهری است اما در حال حاضر شرایط نامناسب زیستپذیری موجب نابرخورداری بخش عمدهای از هموطنان از کیفیتزندگی مطلوب شده است. هدف از پژوهش حاضر مدلسازی ساختاری تأثیر زیستپذیری بر کیفیتزندگی در شهر دورود است. در این پژوهش که ماهیتی کاربردی دارد با روش تحلیلی ـ توصیفی و با ابزار پرسشنامة محقق ساخته، تأثیر عوامل گوناگون از جمله اقتصادی، اجتماعی، زیستمحیطی بر بهبود وضعیت زیستپذیری و تأثیر این شاخص برکیفیتزندگی بررسی میشود. حجم نمونه پژوهش، با بهرهگیری از فرمول کوکران،320 پرسشنامه محاسبه شد و برای استنباطهای علمی مدلسازی معادلات ساختاری و آزمون T به کار گرفته شد. نتیجه پژوهش حاکی از آن است که عامل آموزشی، با ضریب رگرسیونی بیشترین اثر را بر زیستپذیری72/0 و عامل زیست-محیطی با وزن عاملی 82/0 بیشترین اثر را در کیفیت زندگی شهر دورود داشتهاند. در نهایت زیستپذیری با ضریب رگرسیونی 98/0 تأثیر بسیار زیادی بر کیفیتزندگی در شهر دورود داشته است.
Structural Modeling of Viability impact on Quality of Life in the Dorud city Introduction Viability is an important factor affecting the quality of life of citizens in the 1980s and the early 1990s became a popular topic (Ahmed et al., 2019: 165). Douglas says that a city's viability by increasing the quality of life in cities is achieved, he believes that the viability based on four indicators, increased life expectancy by investing in the well-being and the talents access to suitable job opportunities, environment live safely and properly attained favorable government (ShabanzadehNaminiet al., 2019: 2). Viability because awareness of dangers such as congestion, rapid population growth, increasing social inequality, and the loss of a sense of belonging and local identity and social life, the quality of life in communities threatens to be formed and grown ( Wheeler, 2001: 9). In terms of viability, a city must be environmentally sustainable living and a good option for livability in the city (Mouratidis, 2018: 19). In Iran country, especially in small cities faces problems such as lack of education, employment, health, recreation, and social, economic, and environmental problems. Methodology The above study is based on purpose and application in the research literature, to collect data and information required from library research and field studies have been used. So that the required information in theoretical literature research through library studies and documents, and process the information and data through the design of city Dorud, in order to understand the study area were collected. Field studies of this study were collected through a questionnaire. The population of the study, residents are Dorud. In order to process data for analysis in the study area of structural equation modeling and statistical analysis methods such as Spss and Amos software to get maps and GIS Arc Nyazaz software is used. The main tool for data collection is a questionnaire. The sample according to the latest census population of 121,638 in 1395, according to the Statistical Yearbook Dvrvdkh derived from the sample is used. According to the formula 30 questionnaires distributed among residents and with respect to the variance obtained from the prototype study. Results and Discussion In response to the hypothesis unfavorable situation in life quality index, Dorud single-sample T-test was used. Other findings from the tests T with 95/0 indicate that the quality of life (economic, social, health) was significant and only social index is generally not significant, but it all averages indicators and statements they are less than desirable. So we can say that the quality of life index Dorud is not in good condition. The results of the structural equation model show that the indicators of quality of urban life and livability index which are more important and more significant effects than other parameters have been specified. We see that the structure of the research in environmental management model as independent variables affect the quality of life as the dependent variable. The second and third latent variable quality of life of 15 significant change is made. The findings of the second-order factor model indicate that the therapeutic agent with the highest load factor accounted for 0.80 weight and higher status than the rest of the index. Then social factor loadings 0.57 is the economic factor is the time factor 0.49 in the last place. Conclusion Because of the unprecedented growth of the number of people living in cities, living in cities increasingly challenging in a way that if the current population continues cities with tension face, which significantly affects the quality of life and livability in the urban cities, Urban management, to make the city habitable and quality of life need to strengthen effective measures in relation to the pay zone. All assumptions of the study, after the test, all of which have been approved in the summary of the analytical results of the analysis can be expressed. It Dorud residents of the city in terms of livability and quality of life in terms of education and health facilities Brd.kmbvd not favorable to the greatest effect on the viability of discontent with the situation in different areas of the city have been Dorud. The economic situation of other important indicators in this study and reflects the economic hardship due to lack of employment opportunities, lack of job security and lack the financial ability to solve problems in this city is that it has a direct impact on the viability and studied the quality of life in the city. Lack of facilities in small towns is a fundamental problem in developing countries where structural model study, improve infrastructure, the environment is important. Quality of housing, social and other factors affecting the viability to continue that ultimately affects the quality of life in a city
