Exploration On The Multidimensional Urban Residential Community Planning Theoretics

City is a social community with urban residential community as a basic cell, the urban residential community is not only a living area traditionally, but also a basic urban unit to promote building the harmonious society, take residents interacting and public participation as foundation. Along with the economic development and social transformation, many problems emerge in our country, such as the stratification, the aging of society, the alienation of community space, the confusing of community organizations and management, the diluting of community perception and the poor community environment etc. Although our community planning has presented the trend of transition to "humanistic - social", it is still lack of systematic theories and methods, which can guide the practice of community development and planning practice. It undoubtedly has important theoretical and practical value to explore the theories and methods of the modern community planning from multidimensional perspective, with the wide and generous urban residential community as a focal point.The methods concluding theoretical study and representative case analysis, field survey and statistical analysis, qualitative analysis and quantitative analysis, are used combiningly. Based on reviewing and summarizing the theories of urban community planning both home and abroad, combined with the investigation and analysis of residential community of Xi'an, the theoretic frame of the multidimensional urban community planning is constructed. Then the realized approach to constructing the harmonious city with community as a basic unit is discussed.(1)Based on the comparison between community planning both home and abroad, we find many problems which can be described as follows: more theoretical analysis but less empirical studies, more single field studies but less integrated crossover studies, more static studies but less dynamics researches, more community hard environmental studies but less soft-hard environment integrated comprehensive researches, the pertinence and instruction of theories is weak too. (2)Aimed at the above issues, the community phenomena analysis indicators and the community satisfaction evaluation system are established. Then the paper investigates the community phenomena and community satisfaction of Xi'an universally and typically, and analyzes the findings with statistical method and fuzzy comprehensive evaluation method, and then points out the "Humane Care" and "Approach Nature" would be the main concern of community planning for the future.(3)The theoretic frame of the multidimensional community planning is constructed. Community planning has multi-attribute and multidimensional characters ,which are systemic, social, economic, spatial, ecological and sustainable characters. The multidimensional community planning includes 6 key elements: determining community optimum-scale, designing ecological and sustainable building, humanized transport facilities planning, environment facilities planning, public facilities planning and public participation system designing.(4) It is discussed that the conceit and the approach to constructing the harmonious city with community as a basic unit.
