摘　　要：为从环保角度控制区域土地开发强度,提出了基于环境空气容量的区域土地最大出行产生率确定方法.将用A值法计算出的区域大气环境容量的一部分分担为区域环境空气容量,把由路网容量换算的车辆污染物排放量与区域环境空气容量作比较,通过调节路网流量使比值为1.剔除过境交通后,利用OD反推理论和调节后的路网流量反推出各小区出行量,根据区域总出行量和可利用土地面积计算出区域土地最大出行产生率.以深圳市某区域路网进行算例分析,结果表明:该方法能够确定环境空气容量约束下的区域土地最大出行产生率,在土地开发时考虑环境空气容量,有助于从根源上保护交通环境。To control the regional land development intensity from the environmental protection point of view,proposed method for determining the regional maximum trip generation rate based on environmental air capacity.A part of regional atmospheric capacity calculated by A value method was shared for environmental air capacity.Road network capacity was equivalent conversion to vehicle pollutant emissions.Then adjusted the network traffic volume to let vehicle pollutant emissions was equal to environmental air capacity.After removed transit traffic,used OD matrix estimation theory and adjusted network traffic volume to estimate traffic trips of each traffic zone.According to total traffic trips and available land area,regional maximum trip generation rate was calculated out.A certain region was selected as a numerical example and the result shows that proposed method is effective.Considering environmental air capacity in land development,it helped to protect traffic environment from root cause.
