高速铁路的造价成本和技术要求高、施建标准严格苛刻、管理维护复杂困难，因

High-speed railway construction cost and technical requirements, demanding strict standards applied to build, manage and maintain complex and difficult, and therefore high-speed rail construction premise is a rich source, strong economy, strong science and technology, suitable terrain and advanced management. Blind construction of high-speed rail is not only costly, but also damage the environment.

High-speed railway cost and technical requirements are high, strict and strict construction standards, management and maintenance difficulties, so the construction of high-speed rail is premised on a rich source of customers, strong economy, strong science and technology, suitable terrain and advanced management. Blind construction of high-speed rail will not only hurt people's wealth, but also damage the environment.

The high-speed railway has high cost and technical requirements, strict construction standards and complex management and maintenance difficulties. Therefore, the premise of high-speed railway construction is rich passenger resources, strong economy, strong science and technology, suitable terrain and advanced management. Blind construction of high-speed rail will not only cost people money, but also damage the environment.<br>
