Abstract:

In recent years, in order to create a better and more suitable space for living and work, and also for improving the living standard of people continuously, whether a city is amenity city has become the research focus of scholars. Hence attention should be paid to the research on spatial characteristics of urban residential suitability which are still inadequately dealt with.Study on the spatial structure of urban residential suitability and restrict factors has great theoretical and practical significance to urban development programming and city environmental planning. Therefore choosing convenience, health, safety, environment comfort level and convenience of going out to travel as the indexes, questionnaires are designed to investigate the residents who had stable life in Dalian for more than half a year. Then the spatial characteristics of urban residential suitability in Dalian are evaluated by AHP and Q cluster analysis method taking administrative divisions and functional regions as basic unit.And the analysis is based on the data of quantifiable questionnaires.We hope that it can provide reference for the urban construction of Dalian.The following conclusions are drawn: In citizens'opinion, some differences exist in urban residential suitability in different districts,and in downtown, the satisfaction descends gradually from the eastern coastal region to the northwestern urban-rural-integration-area. Comparatively speaking, the urban residential suitability in Zhongshan district is the best contrarily, Ganjingzi district in urban-rural-integration-area is ranked last in urban residential suitability evaluation. And in outer suburbs, urban residential suitability satisfaction in Lushunkou district and development zone is higher than Jinzhou district. At the same time, the result of clustering analysis of different functional regions shows that the area which is political, economic and commercial center of Dalian has the highest score of urban residential suitability; the intersections of urban and rural areas in northwest of the city have the lowest score; although the urban residential suitability in some of the outer suburbs is better, the difference is significant among indicators. On the whole, the score descends gradually from city center to suburbs in spatial pattern and divergences of indexes are also lager. It accords with the result of evaluation on district.

Key words: Dalian, urban, residential suitability, spatial evaluation
