济南首条地铁开始运营-凯发k8官网

people in jinan, capital city of east china's shandong province, got one more reason to celebrate the new year as their first ¹ line started operation tuesday.

 

济南人民庆祝新年的理由多了一条：第一条地铁周二开始运营。

 

earlier, jinan, known as "the city of springs" due to its large number of natural artesian springs, was one of the last few ² capitals with no metro service.

 

the springs bring tourists to the city, but also pose a ³: to develop underground transportation or to protect groundwater?

 

the launch of the first metro line came three decades after local authorities first proposed to construct the metro system and ⁴ construction plans several times amid fears any construction might affect the springs.

 

in 1988, authorities in jinan first proposed to build the metro system after conducting a survey on residents' ⁵ options, according to zhao yanzhu, an 80-year-old expert in the field of hydrogeology, who has witnessed the ups and downs of the city's metro system development.

 

after years of study and debates, experts finally agreed in 2009 that as long as the metro lines avoid the downtown where the majority of springs are concentrated, the construction would not have an impact on the groundwater system, according to li liping, professor with shandong university and deputy chief engineer of the jinan rail ⁶ group, one of the constructors.

 

mainly located in the western part of the city, the first metro line covers a distance of 26.1 km with 11 stations, expected to help ease traffic congestions in the city.

 

"we have waited for a long time, but it is worth waiting for," said local resident xin an, one of the first passengers of the metro line, construction of which started in 2015.
