所以地铁的常规做法是一半的人口密集老城区一半的人口稀少开发区并不完全为交通服务。当一个城市新建一条地铁完成是为了交通服务而不要走郊区那这个城市就是很有前途的城市值得你留下的城市所以地铁对于一个城市它作为人民交通工具的作用是次要引导人口去新开发区是主要。对于一些老城区地铁是弱化效果它拉高了附近的土地让老城区将来的改造带来极大麻烦。大家都说买房主要看地段地段地段但平民很难判断将来的地段在哪里现在的地段

The conventional approach of subway construction is to serve both densely populated old urban areas and sparsely populated development areas, rather than solely for transportation purposes. When a city constructs a new subway line, it is intended to serve transportation needs and not to avoid suburban areas. Therefore, such a city is considered to be a promising and worthwhile place to live in. The role of the subway as a means of transportation is secondary, while its primary function is to guide population growth towards new development areas. For some old urban areas, the subway has a weakening effect, as it raises the value of nearby land, posing significant challenges for future urban renewal. It is widely acknowledged that the most important factor in real estate investment is location, but it is difficult for ordinary people to judge where the future prime locations will be. Therefore, a simple rule of thumb is to consider the number of subway lines available: one, two, or three. Unlike buses, subway lines cannot be easily changed. For a city, the subway serves as a blueprint for urban development, while for residents, it is a path to prosperity, not only for buying houses but also for other investments, especially for second- and third-tier cities
