BACKGROUND The recent increase in childhood obesity is expected to add significantly to the prevalence of chronic diseases. We used multivariate multilevel analysis to examine associations between parks/green space and childhood overweight/obesity across communities in Calgary, Canada, a city characterized by intensified urban sprawl and high car use. METHODS Body Mass Index was calculated fr...

Urban green mapping has become an operational task in city planning, urban land management, and quality of life assessments. As a multi-dimensional, integrative concept, urban green comprising several ecological, socio-economic, and policy-related aspects. In this paper, the author advances the representation of urban green by deriving scale-adapted, policy-relevant units. These so-called geons...

Sustainable settlement is one of the key constituents of sustainable development, and sustainable urban development can be defined in this framework. Emergence of sustainable development as a commonly-used phrase has caused several controversies about urban forms. Today’s urban form is known as a source of environmental problems. Undoubtedly, this phrase has persuaded many of researchers to sea...

many epidemiological studies have found that people living in environments with more green space report better physical and mental health than those with less green space. however, the association between visits to green space and mental health has seldom been studied. the environment surrounding residences and its recreational and commuting opportunities are believed to affect human health and...

Study on landscape spatial pattern in the center of Chengdu City is based on the Landsat-8 image by using 3S technique and spatial pattern analysis software Fragstats 3.3. The results showed that there covered an area of 193.92 km2 in the center of Chengdu City. 55.24% of the total area was made up of buildings, covering an area of 107.12 km2, and the overall landscape of impervious ground-base...

This study investigates the effects of compact urban development on air pollution, taking into account both the spatial distribution of pollutants resulting from an increase in inner urban densities and the dispersion of pollutants associated with an increase in outer green open spaces. The empirical analysis is based upon a panel data model covering 17 cities in Korea from 1996–2009; this appr...
