Abstract:
پراکنده‌رویی پدیده‌ای است که تاثیراتی بر کیفیت زندگی دارد. این پژوهش به بررسی رابطه بین کیفیت زندگی با پراکندگی و فشردگی شهری در شهر خرمدره می‌پردازد. برای انجام پژوهش از روش‌های قیاسی، اسنادی و نرم‌افزارهای GIS، SPSS، LISREL 8. 5 و برای تحلیل داده‌ها از آزمون‌های من‌ویتنی، t و تحلیل عاملی استفاده‌شده است. محله‌های شهر خرمدره در دو حوزه پراکنده و فشرده دسته‌بندی شدند که چهار محله به‌صورت تصادفی ساده انتخاب شدند و حجم نمونه برای سنجش آن بر اساس فرمول کوکران 130 عدد محاسبه شد. نتایج نشان می‌دهد که کیفیت زندگی در حوزه پراکنده بالاتر از حوزه فشرده با اطمینان 95 درصد قرار دارد.
This paper examines the relationship between urban Sprawl and urban compaction with quality of life. By technology progress and the use of fast means of transportation, the deployment of citydwellers was possible in rural areas around the city. However, due to problems in urban centers (such as high price of housing and land, over population jamming, etc.) population is poured into the suburb and on the other side due to the existence of highways, they were able to meet their requirements easily by refering to urban centers where it was caused spread cities horizontally. Urban sprawl event was stared at the united states in twentieth century then it was taken in to place in other countries like Iran. And surely conseques of this event have had some effect on quality of life (positive or negative). The purpose of this study is to investigate the effects of urban sprawl on the quality of life and the sample is Khoramdareh city. The main question in this study is that if the urban sprawl affects on the quality of life and how much is it? Therefore, after the study and examination of the theories, concepts and approaches to the phenomenon of urban sprawl and quality of life, the global experiences in respect of sprawl and quality of life and indicators of their measurement was investigated. First in the evaluation of case study, causing factors of dispersion in Khoramdareh was analyzed and then urban sprawl was investigated by examining 13 factors in 12 urban district. It was divided into sprawl district (1, 2, 3, 4, 10, 11, 12 neighborhoods) and compact districts (5, 6, 7, 8, 9 neighberhoods). Then urban neighberhoods of Khoramdareh gradation based on sprawl from 1 until 12 dirges (11, 12, 10, 1, 4, 2, 3, 5, 7, 8, 9 and 6 neighberhoods). Also quality of life by 18 indexes and questionnaire design by 18 indexes and by filling it in Khoramdeh selected neighberhoods (1 and 11 neighborhoods from sprawl district and 6 and 8 neighborhoods from compact district) were evaluated. The number of questionnaires was calculated by Cochran formula and the number rose to 130 in the four neighberhoods of Khoramdeh and by Using of this technique, the samples were made to collect data. Then the questionnaire data were analyzed and summarized by using of descriptive statistics tools (tables and charts) and finally analyzed by using of inferential statistical techniques and the results was granted with a certain confidence level of extension. Used analysis includes: Mann-Whitney Test and t Test by using of SPSS16 software and exploratory factor analysis by using the LISREL 8.5 software. The results show that the quality of life in 1 and 11 neighborhoods (ave = 2/5) is upper than the quality of life in 6 and 8 neighborhoods (Average = 2/22), with 95 percent confidence level. And then by this 95 percent confidence level, it can be said that quality of life in sprawl neighberhoods is upper than the quality of life in compact neighborhoods.
