در این مقاله برانست که تاثیر یارانه ها و نظام توزیع آن بر مهاجرتهای روستایی و روند شهرنشینی در ایران را مورد بررسی قرار دهد موضوعی که پیش از این ادبیات جغرافیایی کشور کمتر از این منظر به آن پرداخت است به این منظور ابتدا ساختار و بافت یارانه ها در دو مقطع قبل و بعد از انتقال اسلامی مقایسه شده است سپس نحوه توزیع بخشی و جغرافیائی یارانه ها توسط دولت ارزیابی شده است و نهایتا پیامدهای فضایی و جغراف...
Beijing has experienced rapid urbanization and associated urban heat island effects and air pollution. In this study, a contribution index was proposed to explore the effect of urbanization on land surface temperature (LST) using Moderate-Resolution Imaging Spectroradiometer (MODIS)-derived data with high temporal resolution. The analysis indicated that different zones and landscapes make diurn...
This paper intended to examine the seasonal variations in the relationship between landscape pattern and land surface temperature based on a case study of Indianapolis, United States. The integration of remote sensing, GIS, and landscape ecology methods was used in this study. Four Terra's ASTER images were used to derive the landscape patterns and land surface temperatures (LST) in four season...
Background: Accidents, such as domestic accidents, and the resulting injuries are presently a matter of concern in communities. Some factors such as urbanization cause an increase in the incidence of accidents for recognized and unrecognized reasons. The aim of the present study was to investigate the incidence of domestic accidents among a group of families who had migrated to the determined u...
The article is devoted to the diagnosis of state urbanism and urbanization trends in world, its individual regions Ukraine. etymology term "smart" peculiarities modern scientific approaches interpretation have been established. relationship difference between concepts "urbanism" "urbanization" are studied: considered as a process spatial evolution society due growth urban reduction rural popula...
The combined effect of urbanization and agriculture, two most pervasive land use activities, on the surface climate remains poorly understood. Using Moderate Resolution Imaging Spectroradiometer data over 2010–2015 and forests as reference, we showed that urbanization warmed the land surface temperature (LST), especially during the daytime and in growing seasons (maximized at 5.0 ± 2.0°C in May...
China is undergoing rapid urbanization during the past decades. For example, the proportion of urban population in Beijing has increased from 57.6 % in 1980 to 86.3 % in 2013. Rapid urbanization has an adverse impact on the urban rainfall-runoff processes, which may result in the increase of urban flood risk. In the present study, the major purpose is to investigate the impact of land use/cover...
The difference in land surface temperature (LST) between an urban region and its nearby non-urban region, known as surface urban heat island intensity (SUHII), is usually positive as reported in earlier studies. India has experienced unprecedented urbanization over recent decades with an urban population of 380 million. Here, we present the first study of the diurnal and seasonal characteristic...
In this paper, we present surface urban heat island (SUHI) analysis of Shanghai (China) based on the change in land use and land cover using satellite Landsat images from 2002 to 2013. With the rapid development of urbanization, urban ecological and environmental issues have aroused widespread concern. The urban heat island (UHI) effect is a crucial problem, as its generation and evolution are ...
We investigate the effects of the construction of the national highway system in China on local economic outcomes. The analysis employs three main approaches. The first is based on a structural model of Ricardian trade that provides an explicit description of the general equilibrium effects of changes in the highway network. The second involves reduced form estimates of the casual effects highw...
