The issue of pedestrian-friendly urban environments has been of increasing importance lately in urban planning and design. In order to develop a better knowledge about the walkability of the built environment, it is important to understand the complexity behind walking behavior. Since different kinds of walking activities vary in their goal, effort, frequency, duration, etc., they also vary in ...

Meanwhile, the rapid urbanization process has led to the great changes of urban landscape in China, and it also has had certain impacts on environmental factors such as climate, soil, hydrology, biodiversity, etc., then it has made the overall ecological environment deteri...

The urban environment characterized by various stresses poses challenges to trees. In particular, water deficits and high temperatures can cause immense drought stress to urban trees, resulting in reduced growth and die-off. Drought-tolerant species are expected to be resilient to these conditions and are therefore advantageous over other, more susceptible species. However, the drought toleranc...
