摘　　要：在节约集约用地的背景之下,“小街区,密路网”模式在我国规划建设中得到推广应用.然而增加的道路和后退红线面积会带来城市实际建设用地的减少,与节约集约用地原则相悖.通过结合相关规范和标准建立模型,对小街区模式下的实际城市建设用地利用情况进行定量分析,得出小街区模式中,道路与后退红线面积的增加会造成城市实际建设用地的明显减少的结论.从不同角度论证后退红线的根本目的是应保证具有私权的开发用地不对其相邻的道路用地产生干扰,并提出小街区模式的后退红线应实行强制性和引导性结合、精细化和具体化结合的节地模式,在满足后退红线根本目的的原则上尽量节约城市建设用地.Under the background of economical and intensive use of land,“small bock size,high street density”pattern has been popularized and applied in China's planning and construction.However,the increased area of roads and the building restriction setbacks will lead to the reduction of urban construction land,which is contrary to the principle of economical land use economical and intensive land use.Based on the relevant norms and standards,a model is established to quantitatively analyze the actual utilization of urban construction land under the small block mode size,and it is concluded that increased area of roads and building restriction setbacks in the small bock size pattern will result in a significant reduction of urban actual construction land.It is argued from different perspectives that the fundamental purpose of the building restriction setbacks is to ensure that the development land with private rights from affecting the adjacent road land,and it is proposed that the building restriction setbacks in the“small bock size”pattern should implement the land saving mode of the combination of compulsion and guidance,refinement and concretization,and save urban construction land as much as possible in line with the principle of meeting the fundamental purpose of the building restriction setbacks.
