Study on the Coupled Coordination Degrees between Urban Land Intensive Use System and Social Economic Development——A Case of Shandong Province

On the basis of the construction of index system, by the factor analysis and the model of coupled coordination degree, the coupled coordination degrees in 2005 and 2010 between development of urban land intensive use system and social economic system are studied in 17 ground level cities of Shandong province. The first results showed that f(x) and f(y) in 2010 were higher than in 2005, which indicated that the degree of urban land intensive use and development level of the social economy were improved. The second results was that the coupled coordination degree of two systems was higher than in 2005, but if f(x) and f(y) were smaller, the gap in the capacity of comprehensive coordination was larger, the coupled coordination degrees were the smaller. So comprehensive development levels in single system were improved, which could not promote positive development between two systems.
