Urban green spaces and plant diversity at different spatial–temporal scales: a case stUdy from beijing, china.— Beijing, the capital city of China, is one of the largest and most rapidly-urbanizing cities in the world. In this work, we present the main results of one decade’s research on urban vegetation and plant diversity changes in different urban structural units. Urban vegetation/plant div...

Large-scale models are generally associated with big modelling units in space, like counties or super grids (several to dozens km). Few applied urban models can pursue largescale extent with fine-level units simultaneously due to data availability and computation load. The framework of automatic identification and characterization parcels developed by Long and Liu (2013) makes such an ideal mod...

Consensus is lacking on specific and policy-relevant measures of neighborhood attributes that may affect health outcomes. To address this limitation, we created small standardized geographic units measuring the transit, commercial, and park area access, intersection, and population density for the Portland, Oregon metropolitan area. Cluster analysis was used to identify six unique urban forms: ...

It has been suggested that the method of constructing an urban spatial structure typically follows a forward process from planning and design up to expression, as reflected in both graphic and text descriptions of urban planning. Although unorthodox, the original status structures can be extracted and constructed from an existing urban land-use map. This approach not only provides the methodolo...

The influence of urban design on economic vitality has been analyzed by a number of researchers and is also a key focus of many planning/design theories. However, most quantitative studies are based on just one city or a small set of cities, rather than a large number of cities that are representative of an entire country. With the increasing availability of new data, we aim to alleviate this g...

Large-scale models are generally associated with large spatial modelling units, for example, counties or super grids (several to dozens of km2). Few applied urban models can achieve a large spatial coverage with irregular spatial units due to data availability and computation load. The framework of automatic identification and characterization of blocks developed by Liu and Long (2016) makes su...

Generally, more than 60 percent of land in cities and around 40 percent in small towns are utilized as housing areas. The present research aims to investigate the price of urban housing lands in Iran during the years 2001-2011 in different provinces. The method of research used in this paper is descriptive/ analytical method. After gathering the data in this regard via the Central Bank of Iran,...

Municipalities as well as any other organization have needed assessment and efficiency measurement to make better use of their limited resources and greater effectiveness. The aim of this study is to evaluate the efficiency of municipalities, determining efficient and inefficient municipalities using data envelopment analysis, and classifying the municipalities using Anderson Peterson technique...

John Decker has been studying the form of the contemporary city and the application of cutting-edge digital representation techniques, including film making, in the urban design and planning processes for many years. In this provocative article he challenges us with the need of a comprehensive urban design theory, and discusses some of its fundamental analytical layers: mass, movement, scale, g...
