land- phone, like mobile, internet and fax is a communication device and has network externality effect. thus as the penetration coefficient increases, the network effect improves. the transmission of information via the word of mouth is the main source of enhancing the network externalities coefficient. in this article we have investigated the factors affecting the network externality coeffici...

The processes of land use and cover change (LUCC) are highly diverse complex, being heavily influenced by natural factors, economic other related factors. These changes have a significant impact on ecological environments landscapes, serve as reflection human activity, limited As result, LUCC has been widely studied across multiple scientific disciplines. In particular, considerable progress ma...

Optimizing land-use allocation is important to regional sustainable development, as it promotes the social equality of public services, increases the economic benefits of land-use activities, and reduces the ecological risk of land-use planning. Most land-use optimization models allocate land-use using cell-level operations that fragment land-use patches. These models do not cooperate well with...

Under the premise that land administration is one of the necessary components of sustainable development and better land management, this article reviews how progressive titling could foster new land administration procedures and associated information systems. This review is based on the objectives of progressive titling as they are developed or currently implemented in various regions in the ...

The advantage of ENVISAT ASAR over its predecessors, namely ERS-1 and ERS-2, as a land observation tool resides in its multiple polarization and multi-look angle capabilities. As a radar sensor the ASAR backscattering coefficient is sensitive to the moisture content of the scattering media and its geometrical properties (i.e. size, shape, roughness, and orientation). From the quantitative analy...

Rapid urban land expansion and the resulting arable land loss have put food security in China at risk. This paper investigates the characteristics and mechanism of arable land conversion in Beijing using a logistic model based on land-use data for 2001 and 2010. The results suggest that (1) arable land conversion tends to occur near built-up areas, city centers and major roads; (2) arable land ...

Despite the progress made in controlling local air pollution, urban areas show increasing signs of environmental stress and air quality is one of the major concerns. The findings of several studies provide evidence that the shape of a city and the land use distribution determine the location of emission sources and the pattern of urban traffic, affecting urban air quality. This work focuses on ...
