The province of Jiangsu, our home, is also home to the most cities with metro lines in all of China. And if that’s not enough, recent openings together with those on the horizon shall soon also put the province in first place as regards total number of lines and track length.
我们的家乡江苏省也是全国拥有地铁线路最多的城市的所在地。如果这还不够，最近的开通以及即将开通的开通也很快将使该省在线路总数和轨道长度方面名列第一。
On 28 June, Changzhou Metro Line 2 and Xuzhou Metro Line 3 began operation. The following day came the opening of Suzhou Metro Line 5.
6月28日，常州地铁2号线、徐州地铁3号线开通运营。次日，苏州地铁5号线开通。
Province wide, Jiangsu has at present five cities with operating metros, namely Nanjing, Wuxi, Changzhou, Suzhou and Xuzhou, more than anywhere else.
全省目前有南京、无锡、常州、苏州、徐州5个城市开通地铁，数量最多。
But why? It all boils down to requirements set down at the national level as to thresholds that need be met before any plan for a metro system can be approved.
但为什么？这一切都归结为国家层面规定的要求，即任何地铁系统计划获得批准之前需要满足的门槛。
The first of these is financial. A city in China need have an annual GDP of more than ¥300 billion in order to qualify for a metro, reports The Paper. In Jiangsu, all 13 cities meet the criteria. By comparison, Guangdong Province comprises 21 cities, many of which are relatively small and only able to dream of one day having a metro.
第一个是财务方面的。据澎湃新闻报道，中国一座城市的年GDP必须达到3000亿元以上，才有资格建设地铁。江苏13个城市全部符合标准。相比之下，广东省有21个城市，其中许多城市规模较小，拥有地铁只是梦想。
The other main criteria is a population of at least 7 million, of which the urban permanent population need exceed 3 million. With the release of the 2020 census, Guangdong still only has four cities that meet the criteria, while Jiangsu now has six.
另一个主要标准是人口不少于700万，其中城镇常住人口需超过300万。随着2020年人口普查的发布，广东仍仅有4个城市符合标准，而江苏目前有6个。
With the first five all operating metro systems, so the sixth, Nantong, now has its first line under construction.
随着前五个地铁系统全部投入运营，第六个地铁系统南通目前也正在建设其第一条线路。
And so to the future. By the end of this year, Jiangsu is expected to usher in three new metro lines, namely the Nanjing Jurong Intercity Rail Transit, the west extension of Nanjing Metro Line 2 and Wuxi Metro Line 4.
未来也是如此。今年年底，江苏预计将迎来南京句容城际轨道交通、南京地铁2号线西延线、无锡地铁4号线3条地铁新线。
It is also expected that by the close of 2022, Jiangsu will have 28 metro lines operating in 6 cities. Its total number of lines and track length will hence surpass Guangdong to become China’s number 1.
预计到2022年底，江苏将有28条地铁线路在6个城市运营。其线路总数和赛道长度将超越广东，成为中国第一。
