Spatiotemporal Change of Urban Sprawl Patterns in Bamako District in Mali Based on Time Series Analysis

open access: yesUrban Science, 2020
For decades, urban sprawl has remained a major challenge for big cities in developing countries, such as Bamako. The aim of this study is to analyze urban sprawl pattern changes over time in the Bamako district using landscape index analyses.

Outcomes of applying a geopedologic approach to soil survey in Iran [PDF]

open access: yesDesert, 2017
The paper reviews a set of soil surveys carried out in Iran using a geopedologic approach for different surveying aims in different scales. Most of these studies have implemented a similar survey method including the following steps: delineation of ...

Landscape Environmental Monitoring [PDF]

open access: yes, 2011
Landscape pattern is of primary interest to landscape ecologists and landscape metrics are used to quantify landscape pattern. Calculation of landscape metrics is commonly conducted on completely mapped areas based on remotely sensed data.

Ecological security measurement based on functionality-organization-stability in inland of Three Gorges Reservoir area

open access: yesJournal of Environmental Engineering and Landscape Management, 2022
The spatial-temporal heterogeneity of landscape ecological security has been carried out for the Zhong County in this work based on the framework of “functionality-organization-stability” using the multidate Landsat TM image of 2000, 2006, 2012 and 2018

Do We Need More Urban Green Space to Alleviate PM2.5 Pollution? A Case Study in Wuhan, China

open access: yesLand, 2022
Urban green space can help to reduce PM2.5 concentration by absorption and deposition processes. However, few studies have focused on the historical influence of green space on PM2.5 at a fine grid scale.

Geomorphodiversity index: Quantifying the diversity of landforms and physical landscape

open access: yesScience of The Total Environment, 2017
The physical landscape is the mosaic resulting from a wide spectrum of environmental components. The landforms define the variety, or diversity, of the geomorphological component: the geomorphodiversity. Landforms are usually represented in thematic maps where the scale and the graphic solutions are widely heterogeneous. Since geomorphological maps are

Spatiotemporal analysis of the impact of urban landscape forms on PM2.5 in China from 2001 to 2020

open access: yesInternational Journal of Digital Earth, 2023
Urban landscape forms can be effective in reducing increasing PM2.5 concentrations due to urbanization in China, making it crucially important to accurately quantify the spatiotemporal impact of urban landscape forms on PM2.5 variations.

Quantifying the Scale Effect of the Relationship between Land Surface Temperature and Landscape Pattern

open access: yesRemote Sensing, 2023
The spatial scaling of patterns and processes is a hot topic of research in landscape ecology, and different scales may yield completely inconsistent results. Therefore, to understand the impact of the scale effect on urban heat island effect, this study

A SAR-Based Index for Landscape Changes in African Savannas [PDF]

open access: yesRemote Sensing, 2017
Change detection is one of the main applications in earth observation but currently there are only a few approaches based on radar imagery. Available techniques strongly focus on optical data. These techniques are often limited to static analyses of image pairs and are frequently lacking results which address the requirements of the user. Some of these
