Research on the quantitative indicators of multi-ground system connection efficiency in high-intensity areas
Due to the absence of control indicators for the three-dimensional de-velopment and connectivity of high-inten-sity urban areas,this research conducts a comprehensive review and summation of relevant literature in architectural and urban design pertaining to multi-ground systems,vertical cities,and multi-layered ground sur-faces.Based on this analysis,the concept of"multi-ground systems in high-intensity urban areas"is established.Furthermore,three indicators are proposed to quantify the efficiency of these multi-ground connec-tions:multi-ground system area ratio,multi-ground system connectivity ratio,and multi-ground system performance efficiency ratio.
