Abstract To analyse and characterise land use-land cover (LULC) change, remote sensing (RS) data geographic information system (GIS) approaches are required. The landscape metrics also extensively used to explain the structure pattern of spatial landscape. This case study has been conducted in area Bhagirathi-Hugli River banks West Bengal. area’s satellite image from various periods (1989-2017)...
Quantifying landscape pattern and its change are essential for the monitoring and assessment of environmental consequences of urban area. This paper aims to analyze spatiotemporal patterns of urban landscape changes in Kathmandu Valley, Nepal by combining remote sensing, GIS and landscape metrics. Multi-temporal satellite images from high resolution (CORONA, SPIN and IKONOS) to moderate resolut...
Bioluminescence imaging (BLI) has emerged as a powerful new method to analyse infectious diseases in animal models. BLI offers real-time monitoring of spatial and temporal progression of infection in the same animal, as opposed to euthanizing a cohort of animals and quantifying colony or plaque forming units at multiple time points. Pathogens or mice are engineered to express genetically encode...
Introduction The ecological conservation redline (ECR) policies conducted in China are an important innovation to protect biodiversity, safeguard security, and achieve sustainable development. Pearl River Delta (PRD) area implemented the ECR 2005. Methods This study examines contrast between 15 years before after It also reveals policies' effects by comparing land use change, landscape pattern ...

Often landscape metrics are not thoroughly evaluated with respect to remote sensing data characteristics, such as their behavior in relation to variation in spatial and temporal resolution, number of land cover classes or dominant land cover categories. In such circumstances, it may be difficult to ascertain whether a change in a metric is due to landscape pattern change or due to the inherent ...
Nature reserves play an essential role in protecting natural resources and maintaining an ecological balance. However, certain nature reserves are increasingly disturbed by human activities in the form of settlements, roads, farmland, etc. How to monitor the status of nature reserves by using remote sensing methods has been a focus of scholars for a long time. In this study, remote sensing sate...
بررسی تغییرات پوشش اراضی استان چهارمحال و بختیاری با استفاده از متریکهای سیمای سرزمین (2015-1994)
Due to the importance of accessibility to updated and timely information regarding land cover changes, it is necessary for researchers and managers to assess such provincial level changes to help the planning process and prevent the damages caused in various regions. To this end, the Chaharmahal and Bakhtiari Province land cover changes from 2015-1994 were developed in six main classes using th...
پژوهش حاضر با هدف ارزیابی روند تغییرات ترکیب و پیکربندی عناصر ساختاری سیمای سرزمین شهرستان رشت طی سالهای 1366 تا 1390 طراحی و با استفاده از شیوۀ تحلیل سینوپتیک سیمای سرزمین انجام شد. از اینرو نقشههای سیمای سرزمین از سه فریم تصویر ماهوارهای سنجندۀ TM سالهای 1366، 1378 و 1390 با استفاده از روش تفسیر تلفیقی تهیه شدند. سپس تعدادی از سنجههای ترکیب و پیکربندی سیمای سرزمین شامل تعداد تکه (N...
Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...
