本研究旨在探讨中国城市形态与城市生态效率之间的关系。选取了与城市形态（形态、紧凑度、延伸率和人口密度）和城市生态效率（资源效率、环境效率和总体生态效率）相关的定量指标，并采用遥感和数据拟合分析方法进行了量化。城市形态的形态比和紧凑比与城市生态效率和资源效率呈正相关。城市延伸率与城市生态效率和资源效率呈负相关。在环境效率方面，虽然与人口密度呈负相关，但与紧凑度没有显著相关性。这些结果表明，在中国，设计紧凑的城市可能会导致生态效率和资源效率的提高，但如果人口密度过高，增加的污染成本将导致环境效率的降低。
The present study aims at exploring whether aspects of urban form are associated with urban eco-efficiency in China. Quantitative indicators relating to urban form (form, compactness ratio, elongation ratio and population density) and urban eco-efficiency (resource efficiency, environmental efficiency and overall eco-efficiency) were selected and quantified using remote sensing and data envelopment analysis methods. The urban form aspects of form and compactness ratios were positively correlated with urban eco-efficiency and resource efficiency. Conversely, the urban elongation ratio exhibited negative correlations with urban eco-efficiency and resource efficiency. Regarding environmental efficiency, no significant correlation is found with compactness though a negative correlation is found with population density. These results indicate that, within China, designing cities to be compact may be lead to increases in eco-efficiency and resource efficiency, but if the population density is too high the increased pollution costs will result in a decrease in environmental efficiency.
