摘　　要：重庆古代桥梁主要分布于现主城都市区中的乡镇地区;近代桥梁数量较少,但分布相对均衡,已扩大至万州等区域;现代桥梁数量以主城都市区为中心,向周围递减。从桥梁区域分布现状来看,主城都市区桥梁分布密度最高,渝东北三峡库区及渝东南武陵山城镇群较低。影响桥梁分布的因素依次为城镇化率、地形海拔、人口密度及产业比重。城镇化率对渝东北三峡库区与渝东南武陵山城镇群地区影响较大,而地形及人口密度对主城区都市区,尤其是江津、大足等区域城区影响最为显著。The ancient bridges in Chongqing were mainly distributed in the township areas in the current main city metropolitan area;the number of modern bridges is smaller,but the distribution is relatively balanced,and has been expanded to Wanzhou and other regions;the number of modern bridges is centred on the main city metropolitan area,and decreases to the surrounding area.In terms of the current status of regional distribution of bridges,the main city metropolitan area has the highest density of bridge distribution,while the Three Gorges Reservoir area in northeast Chongqing and the Wuling Mountain townships in southeast Chongqing are lower.The factors affecting the distribution of bridges are,in order,urbanisation rate,terrain elevation,population density and industrial weight.The urbanisation rate has a greater impact on the Three Gorges Reservoir Area in northeast Chongqing and the Wuling Mountain Townships in southeast Chongqing,while the topography and population density have the most significant impact on the main urban metropolitan areas,especially the urban areas of Jiangjin and Dazu.
