Portraying urban functional zones provides useful insights into understanding complex urban systems and establishing rational urban planning. Although several studies have confirmed the efficacy of remote sensing imagery in urban studies, coupling remote sensing and new human sensing data like mobile phone positioning data to identify urban functional zones has still not been investigated. In t...

 Both visual and service quality of urban landscape play an important role in the process of visual visibility assessment and effectiveness of these services as well. Given the fact that the existence of dead, cold, and soulless spaces in cities is affected by heterogeneity and visual contamination that is free from eye-catching and desirability. Therefore, this research seeks to evaluate the v...

In the preceding chapters we discussed the central role that spatial and temporal variability play in ecological systems, the importance of addressing these explicitly within ecological analyses and the resulting need to carefully consider spatial and temporal scale and scaling. Landscape ecology is the science of linking patterns and processes across scale in both space and time. Thus landscap...

Facing urban warming, mitigation and adaptation strategies are not efficient enough to tackle excessive urban heat, especially at the local scale. The local climate zone (LCZ) classification scheme is employed to examine the diversity and complexity of the climate response within a city. This study suggests that zonal practice could be an efficient way to bridge the knowledge gap between climat...

providing efficient programme to promote urban landscape is considered as one of the most significant element of development in developed cities. the significance will become more considerable in edges of megacities where a lot of environmental, social, and economic issues are evident. this article is trying to deal with the importance of landscape control in relation with a neighborhood by sug...

1. introduction environmental changes can be monitored at many scales but the scale of landscape and region has more information in support of sustainable spatial planning. the availability of remote sensing imagery provides multi-scale observation with periodic repetitions over time. landscape and regional scales are adequately covered by satellite images. remote sensing images provide non-ave...

This paper develops an integrated strategy to model the urban development and ecological dynamics in the Central Puget Sound Region. This effort is part of the Puget Sound Regional Integrated Synthesis model (PRISM) – an interdisciplinary initiative at the University of Washington aiming to develop a dynamic and integrated understanding of the environmental and human systems in the Puget Sound....

As the global population urbanizes, dramatic changes are expected in city lighting and the urban form, which may threaten the functioning of urban ecosystems and the services they deliver. However, little is known about the ecological impact of lighting in different urban contexts. Movement is an important ecological process that can be disrupted by artificial lighting. We explored the impact o...

  Background and Aim : Contamination of the surface soils of the urban ecosystem with heavy metals poses potential ecological risks. In this research, a preliminary investigation was carried out to evaluate the potential ecological risk of cadmium and lead contamination in urban park soils in Assadabed City, Iran.   Materials and Methods : Soil samples were taken from the urban parks of Asad...
