2016年城乡建设公报发布 山东城市建成区面积全国第二

2017-08-25 18:25:56   央广网

江苏这一占比达到3.91%,位居第四。江苏土地总面积不大,且省内以平原为主,经济发达,城市人口密布。广东这一比例也超过了3%。另外,山东和浙江分列6~7位。

从建成区面积占比来看,占比高的主要集中在东部沿海发达地区,这些地方土地面积相对较小,经济发达,人口众多,城市化比例较高。所以前七名都是位于东部沿海。

当然,建成区面积占比的高低,也受到地形地貌的影响。例如福建,作为东部沿海地区山地最多、平原最少的省份,素有“八山一水一田”之说,城市和人口规模都相对较小。相同情况还有中西部的湖北、安徽、河南等地。

全国39城正在建轨道交通 济南首条地铁进入铺轨阶段

随着城市规模尤其是中心大城市的不断扩大,城市轨道交通的建设规模也在日益扩大。

公报》显示,2016年年末,全国有30个城市建成轨道交通,线路长度3586公里,分别比上年增加6个城市,增长16.8%,车站数2383个,其中换乘站541个,配置车辆数19284辆。

记者统计,截至2016年底,共有10个城市的运营里程超过了100公里。

其中,截至今年3月,上海地铁运营里程合计617公里,长度位居世界第一,开通投入运营地铁站达367座,上海市公共交通一半客流量都由地铁承担。

北京地铁运营线路共有19条,总里程574公里;广州地铁线网总里程为308.7公里,位居全国第三、世界前十;深圳地铁总运营里程已达到285公里。此外,南京和重庆的里程都已经突破了200公里。

据不完全统计,未来5年世界范围内城市轨道交通的建设80%在中国。《公报》显示,2016年,全国共有39个城市正在建轨道交通,线路长度4870公里,比上年增加1个城市,增长21.9%,车站数3080个,其中换乘站827个。

据了解,8月20日上午9时16分,在济南轨道交通R1线始发站池东铺轨基地,中铁一局铺轨工人操作着两台龙门架,将一节25米轨排顺利铺装到高架桥面线路上,济南首条地铁正式进入铺轨阶段。这也标志着济南轨道交通R1线工程建设重点将由土建施工逐步向机电设备安装重大工序转换。下一步,即将迎来设备安装和车站装修阶段。

广东省体改研究会副会长彭澎分析,中国刚进入汽车时代没多久,每个家庭都想拥有汽车,但由于城市地面交通日益拥堵,发展城市轨道交通才能满足人们日益增长的出行需求。目前,我国多个城市同时修建地铁,规模已经是全世界第一了。

除了一二线城市,地铁建设正在进一步向三线城市扩展,未来将有越来越多的三线城市加入到地铁建设大军。比如,福建省经济总量第一大市泉州,日前公布了《泉州市城市轨道交通近期建设规划(2018~2023)环境影响报告书第一次公示》,两条线路共72.46公里,且全部是地下敷设方式。除了泉州之外,目前包括烟台、唐山、湛江、柳州等众多三线城市也在积极谋划城市轨道交通的建设。
