بررسی ارتباط میان جاذبه‌های گردشگری و کاربری اراضی با استفاده از مدل رگرسیون وزن‌دار جغرافیایی (مطالعۀ موردی شهر اصفهان)

بررسی وضعیت کاربری زمین در مقاصد گردشگری اهمیت زیادی دارد، زیرا گردشگری یک فعالیت منبع پایه محسوب می‌شود. شناخت عوامل تاثیرگذار بر گردشگری، از جمله خدمات و تاسیسات، کمک شایانی در برنامه‌ریزی گردشگری می‌کند. شهرهای بزرگ و توریستی اغلب با مشکلات عدیده‌ای روبه‌رو هستند. قرارگیری مراکز توریستی در بافت تاریخی و سنتی شهر مشکل را دوچندان کرده است. بنابراین، جهت کاهش و پیشگیری تاثیرات منفی گردشگری لازم است برای تعیین الگوی فضایی توریستی شهر و ساماندهی فضاهای توریستی اقدام و برای تامین امکانات و خدمات شهری برنامه‌ای جامع تدوین کرد. وجود آثار تاریخی و باستانی فراوان در بافت سنتی و تاریخی شهر اصفهان، این شهر را به یکی از گردشگر‌پذیرترین شهرهای ایران تبدیل کرده است که ‌این خود لزوم برنامه‌ریزی فضایی گردشگری در این شهر را دو‌چندان می‌کند. تحقیق حاضر با هدف برنامه‌ریزی فضایی گردشگری شهر اصفهان با تاکید بر ارتباط میان جاذبه‌های گردشگری و کاربری اراضی انجام شده است و با توجه به قرارگیری جاذبه‌های گردشگری شهر اصفهان در بافت سنتی شهر در پی پاسخگویی به ‌این سوالات است که الگو و آرایش فضایی جاذبه‌های گردشگری و کاربری‌های اراضی شهر اصفهان چگونه است؟ آیا نظم و الگویی فضایی خاصی وجود دارد؟ جاذبه‌های گردشگری و کاربری‌های اراضی با‌هم در ارتباط‌اند یا به‌صورت تصادفی در فضا پراکنده شده‌اند؟ بنابراین برای پاسخگویی به ‌این سوالات از شبکۀ شش‌ضلعی به‌منزلۀ واحد پایه برای ترکیب داده‌های اولیه استفاده شده است که ابعاد آن‌ها 500 متر برای قطر شش‌ضلعی در نظر گرفته شده و در‌نهایت همۀ سطح شهر به 2383 شش‌ضلعی تقسیم شد. روش پژوهش توصیفی‌ـ تحلیلی است و برای پاسخگویی به مسئلۀ تحقیق از مدل رگرسیون وزن‌دار جغرافیایی استفاده شده است. نتایج حاکی از آن است که کشاورزی نرمال‌ ترین شاخص است و اثرگذاری مثبت و منفی آن یکسان است. صنایع بیشترین اثرگذاری مثبت و منفی را به‌صورت هم‌زمان بر جاذبه‌های گردشگری گذاشته‌اند و باید در فضاهایی که اثرگذاری منفی است در برنامه‌ریزی‌های آینده تمهیداتی اندیشیده شود. فضاهای فرهنگی و فضای سبز بیشترین اثرات مثبت و مراکز خدمات درمانی بیشترین اثرات منفی را داشته‌اند. کمترین تاثیرات مربوط به شاخص‌های آموزشی و ادارات است.

Investigation of the relationship between the tourist attractions and land use by using geographical weighted regression model (case study: Isfahan, Iran)

Identifying the factors affecting tourism attraction, such as services and installations will help in the planning of tourism. Large touristic cities are often faced with numerous problems. The placement of tourist centers in the historic and traditional structures of cities has doubled these problems. Thus according to the placement of tourist attraction centers of Isfahan in traditional structure, this question is expressed that how the spatial patterns and arrangement of tourist attractions and land uses are in Isfahan? Is there a certain order or spatial pattern for their arrangement? Are tourist attractions and land uses linked together or are they distributed randomly in space? This study has been done in order to make tourist spatial planning for Isfahan with emphasis on relationship between tourist attractions and land use. The hexagonal lattice has been used as basic unit for combining the original data that each diameter of hexagonal is 500 meter, and finally the whole city was divided into 2383 hexagonal lattices. The research method is descriptive analytical. In order to answer research problem, weighted regression model was used. Results show agriculture is the most normal index. Industries have the most positive and negative impact on tourism attraction simultaneously. Cultural spaces and green areas have the most positive effects on tourism attraction and health care centers have the greatest negative effects on it. In addition, the least impact is related to the education and agencies indexes.IntroductionThe recognition of affecting factors such as services and installations on tourism attraction can help in the planning of tourism and have a significant impact on performance and satisfaction of tourists. Most large and touristic cities themselves are faced with numerous problems and this, especially in old cities with traditional structure placed in their centers, has made it difficult to service residents. Therefore, to reduce or prevent negative impacts of tourism, it is necessary to take action for the determination of spatial patterns of tourist and organization of the tourist areas, and in order to provide facilities and civil services such as hotels and resorts, the means of access and transportation, enhancing cultural and artistic attractions, tourist services and encouraged rules, develop a comprehensive program to benefit not only from the local and regional tourists but also from national and international tourists in order to make better use of urban spaces especially in touristic areas to increase incomes and employment and general prosperity. In this study Isfahan, touristic center was evaluated to determine the relationship between the tourist attractions and land use by using geographical weighted regression model. Isfahan is one of the most famous traditional cities in Iran because of its Islamic architecture, with many beautiful boulevards, covered bridges, palaces, mosques, and minarets. There are questions that ask how are the land use patterns and spatial arrangement of tourist attractions of Isfahan? Is there a certain order or spatial pattern? Are attractions tourist and land uses linked together or distributed randomly in space?Methodology of researchIn this study, Polygons data (surface) of tourist attractions and Isfahan’s land use were used. Data is related to the year 1385 and was provided by the municipality of Isfahan in the form of separated layers. The research method is analytical descriptive and in order to answer the questions of the research weighted regression method was used. One of the important parts of this present study is the determination of spatial analysis scale and the size of hexagonal cells. Because if the scale of these hexagonal lattices get too small, false spatial pattern will be formed in space and modifiable areal unit problem cause loss of information in the spatial lattices of the city if the dimensions be considered too big(Good child, 2011), (Baller et al. 2001).Results and discussionA hexagonal lattice was built for modeling and integrating information. In this study Isfahan was divided into 2383 hexagonal grids, and a unique code was assigned to each grid cell. In order to aggregate data, analysis of overlap (Intersect) and the summarization and summarization connection with right triangle lattice was conducted. Then, based on network code, information layers of each land uses was given to the cells. In next step, the cells that had no important information were deleted and finally 1272 cells were remained and spatial analysis was done related to remained data. Sing geographical weighted regression (review of land use impacts on tourism), the output of each column was normalized, and the resulting data were analyzed in seven categories.ConclusionGeographical weighted regression method is a statistical technique that has been adapted for the study of local patterns. This method is in fact a local statistical technique that analyzes the relationship between spatial variables in a nonstationary assumed environment and one of its objectives is to overcome the limitations of the OLS model. This study has tried to introduce the effects of some indexes on spatial pattern of tourism. This indexes are not all parameters affecting tourist attractions, because the tourist attractions are in close connection with other uses. However, according to the available data, 17 indexes were evaluated for the determination of their effect on tourism attraction: landscaping, parking, sports complexes, industrial, medical and health care centers, educational centers and etc. The results show that agricultural is the most normal index. Industries have simultaneously the most positive and negative impact on tourism. Cultural spaces and green areas have the most positive effects and health centers have the greatest negative impact on tourism. Minimal impact indexes are related to educational and governmental agencies.
