Measuring morphology and internal compactness in Harbin, China

The idea of compact city has been considered a development direction of future cities that could promote the healthy and sustainable development of cities. This paper put forward a measurement model of the overall compactness of a city from two perspectives, namely the morphological compactness and the internal compactness; and conducted practical research with the variation of compactness in Harbin from 2007-2017 as an example. Firstly, the morphological compactness of Harbin was measured by built-up area and perimeter; after that, the internal compactness was measured from the perspective of population, economy, transport and land use with entropy method, and the influencing factors of internal compactness analyzed. The results demonstrated that, the overall urban compactness of Harbin showed a fluctuant increasing trend over the past ten years, yet the value of compactness remained at a low level; among others, transport and land use were key influencing factors of internal compactness. In the end, strategies for higher compactness of Harbin was proposed from the perspective of optimization of land use.
