Abstract

The low-carbon urban construction land use level for tourism city is closely related to the sustainable development of the city’s ecological environment and social economy. In this study, the concept of low-carbon urban construction land use level is defined, and then 14 specific indexes are selected from three perspectives of society, economy and ecological environment based on the PSR model, constructing the evaluating index system of the low carbon utilization level for tourism city, exemplified by the tourism city of Hangzhou. The influence factor index of the low-carbon urban construction land use in Hangzhou from 2004 to 2011 is quantitatively evaluated through principal component analysis (PCA). The result shows that tourism city is mostly affected by the industrial economical factor, social economical factor and low carbon environmental factor. Based on this result, the method for optimizing the low-carbon urban construction land use in Hangzhou is provided, which includes strengthening the management of industrial economy of carbon emissions, increasing the supply of land for public transportation and guaranteeing the public greening coverage level, etc., in order to promote the low-carbon urban construction land use in Hangzhou.
