As the transition zone between urban and rural, metropolis fringe is an area where various functions permeate compete fiercely with each other. Understanding land use (LUFs) their relationships are crucial for both rural sustainable development. In this study, we established a conceptual framework of multifunctions in proposed improved evaluation method to quantify LUFs at grid scale. The bivar...

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: ...

Urban–rural integration zones are areas with the most prominent and complex contradictions in economic social, humanistic geographical, urban–rural contexts. Properly identifying such is essential for promoting integrated development rural revitalization efforts. In this study, symbiosis theory urban expansion employed to analyze identify spatial characteristics of main area Dalian City. Two di...

OBJECTIVES This report details the National Center for Health Statistics' (NCHS) development of the 2006 NCHS Urban-Rural Classification Scheme for Counties and provides some examples of how the scheme can be used to describe differences in health measures by urbanization level. METHODS The 2006 NCHS urban-rural classification scheme classifies all U.S. counties and county-equivalents into si...

Urban fringe is the transition zone fine grained with urban and non-urban land cover types. The complex landscape mosaic in this area challenges the land cover classification based on the remote-sensing data. Spectral signatures are not efficient to discriminate all pixels into classes. To improve the recognition and handle the uncertainty, this paper provides a novel integrated approach, based...

The urban fringe which can be seen as a special form of regional ecosystems with a spatial structure gradually from urban to rural areas of transition, has strong heterogeneity and is typical of ecologically sensitive areas. The expansion of city caused wide attention to the landscape effect of the changes. With the help of GIS, we got landscape pattern changes before and after town planning of...

Cities in developing countries are facing serious problems as a result of rapid urban population growth. Not the least of these problems is the creation of environmental stresses at the rural-urban fringe of these cities as they increase in area and envelop fertile surrounding agricultural lands. Because of this rapid rate of growth, sustainable urban environmental management (SUEM) policies an...
