A graph based approach for functional urban areas delineation

Proceedings of the 34th ACM/SIGAPP Symposium on Applied Computing, 2019
In an increasingly urbanized world, where cities are changing continuously, it is essential for policy makers to have access to regularly updated decision-making tools for an effective management of urban areas. An example of these tools is the delineation of cities into functional areas which provides knowledge on high spatial interaction zones and ...

Changes in Migrations in Functional Urban Areas

2019
The chapter will analyse the changes in the intensity and directions of migration in FUAs in the years 1990–2016. More specifically, the directions of population migration from and to the cores/commuting zones according to the size of FUAs will be explored (including total and subperiods).

Evaluating Functions in Urban-Rural Areas

1997
There is a general consensus among the scientific community and the general public that rural areas on the periphery of towns play a strategic role in regional planning.

Functional Urban Areas—Theoretical Background

2019
This chapter explores the theoretical insight behind the concept of functional regions as areas that integrate cities into their immediate hinterland. The literature on urban development from a demographic context will also be explored, including a wide ranging literature overview on population processes, namely the second demographic transition and ...

Changes in Fertility and Mortality in Functional Urban Areas

2019
This chapter presents the natural population change in FUAs in the years 1990–2016. In particular, changes in the number of births, deaths, marriages, divorces as well as total natural increase will be investigated in FUAs and other Polish municipalities and according to the size of FUAs.

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 ...
