Comprehensive evaluation research on the sustainable development of urban infrastructure

Urban infrastructure is the important foundation for urban survival and development. How to alleviate and avoid "city disease" are realistic issues that everybody has to face. Making a comprehensive evaluation for the sustainable development of the city infrastructure is not only the need of urban sustainable development, but also the need of scientific and reasonable planning and construction, as well as meeting the urban sustainable development. This paper puts forward the index system of quantitative analysis, and builds the evaluation system of the urban infrastructure sustainable development. According to the quantitative indicators of the index system, this paper gathers the basic data of urban infrastructure during 2007 similar to 2014 in Wuhan, China and analyzes four secondary indices. Moreover, the paper uses the principal component analysis (pca) to measure the sustainable development of Wuhan infrastructure. Finally, it combines with the situation of Wuhan urban infrastructure sustainable development to put forward the corresponding countermeasures.
