Research on the Compilation of Low Carbon Planning Guidelines for Changxing County, China

During the 40 years of reform and opening-up in China, the process of urbanization developed rapidly. Small towns are faced with challenges such as extensive development, degradation of human settlements, difficulty of retaining local characteristics and features. Therefore, attention should not only be paid to low-carbon emission reduction, but also to the inheritance of local characteristics. Taking Changxing County of Zhejiang Province as an example, according to the natural environment, cultural pattern and local features of Changxing County, we divide the urban characteristic space of the county into four areas： central area, residential area, open space and building site environment. In terms of characteristics of four spatial form and temporal and spatial change of carbon emission, the spatial indexes of characteristic and low-carbon indexes are extracted. Gray correlation method is applied to do coupling analysis of the two series of indexes. Finally, objective system is built to assist the formulation of guidelines and index control. We propose the compilation of low-carbon planning and design guidelines from three levels spatially: macro-level, meso-level and micro-level. We also put forward regional low-carbon planning and design strategies for Changxing County. The aim of this research is to provide reference for the compilation of regional low-carbon planning and design guidelines of small towns, and to provide practical basis for low-carbon construction of small towns. The research is supported by National Key R&D Program of China( 2018YFC0704705).
