Urban agglomeration compactness indicates physical entities, such as city (town), industries, resources, funds, traffic, technologies, whose spatial concentration degree according to specified economic and technologic association in the process of urban agglomerations' form and development, include urban agglomeration industry compactness, urban agglomeration spatial compactness and urban agglomeration traffic compactness. An appropriate compactness reflects the maximum urban agglomerations' efficiency, over-high and over-low compactness are harmful to the healthy development of urban agglomeration. From the viewpoint of industry, space and traffic, this paper constructs synthetic measurement models and synthetically analyzes 23 urban agglomerations' compactness; finds out that urban agglomeration compactness is not high in totality and compactness's spatial discrepancy is great in China. According to the discrepancy and the clustering analysis method, this article classifies urban agglomeration compactness into five grades, highly compact, compact, medium compact, lower compact and dispersed. Urban agglomeration synthetic compactness appears a discrepancy tendency of gradually decreasing from east to west, from south to north. There is highly positive correlation between urban agglomeration synthetic compactness and urban agglomeration development degree. How to scientifically control compactness and which compactness criterion is the optimum choice are the question that this article always painfully ponders on and tries to reply to. The research will provide quantitative policy decision basis for urban agglomerations' form and development, constructing conservation-oriented, environmental-friendly, ecologic and high-efficiency urban agglomerations, establishing scientific basis for promoting the appropriate concentration and healthy development of urban agglomeration in China.
