东西文明曾在这里碰撞,中外贸易曾在这里交汇。作为古代“丝绸之路”发祥地的大西北,历史上曾为人类智慧与创造的交流,为世界的进步与发展作出过不可磨灭的贡献。然而,在漫长的岁月中,战争铁蹄的践踏、自然生态的破坏,特别是海上航线的开辟,却使这里渐渐与世界文明拉开了距离,? Things have clashed here, Chinese and foreign trade has been here to meet. As the birthplace of the ancient Silk Road, Northwest China has historically been an exchange of wisdom and creativity of mankind and has made an indelible contribution to the progress and development of the world. However, in the long years, the trampling of the war ironclad and the destruction of the natural ecology, especially the opening of the maritime route, have gradually distanced itself from the world civilization.
