While benefiting from the efficient and convenient urban life brought by
the highly urbanised society, people are suffering from traffic
congestion, energy shortage, and air and water pollution. In
metropolises, these problems might aggravate city residents' mental
stress, which has aroused a general concern on physical and
psychological health. In this issue, we hope to improve urban spatial
structure and enhance the quality of urban infrastructure, architecture,
and landscape through research and design to form a slower-paced
lifestyle, celebrate cultural identity, and create a more livable city
environment that enjoys a smart use of space, a resource-saving
development, a harmony between man and nature, and, a running efficiency
of cities in which people feel pleasant and comfortable.
