Impact of urbanization on vegetation functional diversity across typical urban areas in China

Journal of Environmental Management
Vegetation diversity in urban areas is crucial for maintaining urban ecological security. Rapid urbanization significantly affects vegetation diversity. However, the absence of effective regional-scale monitoring methods makes quantitative assessments challenging.

The Population Ageing Process in Functional Urban Areas

2019
The chapter will analyse the ageing of the population at the various hierarchical levels of FUAs. The research aims to determine the impact of demographic potential and the size of FUAs on the pace of population ageing in both the core and the external zones. This chapter also explores the impact of suburbanisation processes on differences in the speed

The ecology of urban areas and their functions for species diversity

Landscape and Ecological Engineering, 2011
Despite the appearance of an enormous number of publications about urban ecology and species diversity, many issues are simply opened up rather than explained. The ecological complexity of urban areas, i.e., the variety of determinants and the spatial and temporal dynamic of cities, preclude simple starting points and lines of explanation.

Functional Balance of New Urban Area Planning

2015
A city is a relatively large society, which has a complex synthesis and encompassing system for sanitation, utilities, land usage, housing, and transportation. Both comprehensive and specific new urban areas should be planned based on this fact.

Creation of functional ground models in an urban area

Geological Society, London, Engineering Geology Special Publications, 2001
Rationale The ability to see the ground surface in an urban environment is limited by access and the amount of natural ground exposure. This is typically less than 10% by area. The assessment of the probable ground structure and the behaviour of critical ground elements can be achieved by comparison with non-urban ...

Node functions and traffic flow in urban areas

1995
La memoria presentata al Congresso illustra i risultati di una ricerca finanziata dal Ministero dell'Università per la simulazione dell'effetto dei nodi stradali sulla teoria del deflusso stradale. Vengono presentate alcune curve sperimentali che illustrano l'effetto delle intersezioni sulla riduzione delle velocità medie di deflusso e si propongono ...
