The present study aims to analyze the potential of areas for implementation ecological corridors. area represents a transition between Atlantic Forest and Cerrado domains is extensively fragmented. Geographic Information System was used determine suitable corridors based on their structural potential, while multi-criteria classification generate final map area. Weights notes were assigned veget...

The Amazon Rainforest presents intense pressure from agricultural and cattle farming activities on its forest remnants, which promotes fragmentation. present study aimed to quantify structural changes in the landscape state of Tocantins, Brazil, that occurred between 1985 2020 using Mapbiomas data metrics. MAPBIOMS images were used delimit fragments size classes. Landscape metrics estimated Fra...

با توجه به رشد سریع شهر نشینی در کشور، الگوی­های ساختاری در محیط های شهری به شدت دستخوش تغییر است  فضای سبز شهری نیز مصون از چنین تغییراتی نیست. بنابراین مطالعه در زمینه الگوی فضایی و پراکنش فضاهای سبز به منظور شناسایی ضعف­ها و کمبودها امری ضروری محسوب می­شود. در این مطالعه به منظور بررسی توزیع فضای سبز شهری از تحلیل گرادیان و سنجه­های سیمای سرزمین استفاده شد. به این منظور در طول شش جهت جغرافیا...

Rapid urbanization has accelerated land use and land cover changes, and generated the urban heat island effect (UHI). Previous studies have reported positive effects of neighborhood landscapes on mitigating urban surface temperatures. However, the influence of neighborhood landscape spatial patterns on enhancing cooling effects has not yet been fully investigated. The main objective of this stu...

The semi-arid grasslands in Inner Mongolia (IM) are under increasing stress owing to climate change and rapid socio-economic development in the recent past. We investigated changes in land cover/land use and landscape structure between 1992 and 2004 through the analysis of AVHRR and MODIS derived land cover data. The scale of analysis included the regional level (i.e. the whole of IM) as well a...

Analyzing spatial and temporal changes in landscape patterns is an important aspect of landscape ecology. We used satellite imagery and ERDAS Image software, calculated landscape indices, and quantified landscape transformation processes to determine the nature and magnitude of landscape structural changes within an upland area of the Taishan Mountains in Shandong province, eastern China. We us...

We investigated the movements and selection of settlement sites of translocated pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged, and translocated 59 pygmy rabbits across big sagebrush (Artemisia tridentata ssp.) habitat with 3 categories of landscape fragmentation. We used radio telemetry to track the movements and document the...

Abstract Landslides have a record of deadliest impact in Indonesia during 2015 – 2017. Landslide may be caused by human activities which deteriorate the environment condition such as reconstructing landscapes that reduce ecological functions. Therefore, mapping landslide-prone area is necessary one efforts to mitigate disaster could following. The methods used this study are landscape metrics w...
