摘要：Low carbon has been one of the hottest research topics on global change and sustainable development field, and land use carbon emission is a leading research subject. Taking Hefei City as an example, this paper uses the Decoupling Theory to analyse the relationship of carbon emission and construction land expansion between 1997 and 2012. Based on the decoupling analysis, the Trend Index is established to judge the development direction of the relationship. This study focuses on solving two questions: on the one hand, the strict classification provides an accurate approach for calculating the carbon emission carried by construction land; on the other hand, the paper re-analyses the decoupling states of the two research objects that have same expected development direction, which is falling at the same time. The results show that the ideal decoupling relationship between carbon emission and construction land expansion is in the order of strong decoupling
