Landscape ecological risk assessment in Qinling Mountain
Geological Journal, 2018In this paper, landscape ecological risk in Qinling Mountain was studied. Using the remote sensing images of Landsat TM and DEM data in 1984, 2000, 2005, and 2014, an ecological risk assessment model was constructed, and landscape ecological risk indexes were calculated for four time periods 1984, 2004, 2005 and 2014.

Assessing urban landscape ecological risk through an adaptive cycle framework
Landscape and Urban Planning, 2018Abstract Cities are suffering various ecological risks due to rapid urbanization and global climate change. Urban landscape ecological risk assessment is conducive to identifying high risk areas and guiding risk prevention. However, few studies have characterized the dynamic processes of landscape ecological risk.

Ecological risk assessment (EcoRA) generally suffers from limited application of ecological knowledge in the definition and characterization of real-world sites. Not surprisingly, most remediation decisions, which follow, have little or no relationship to the valued ecological resources of the site or the broader region.

Riverine landscape dynamics and ecological risk assessment
Freshwater Biology, 20021. The aim of ecological risk assessments is to evaluate the likelihood that ecosystems are adversely affected by human‐induced disturbance that brings the ecosystem into a new dynamic equilibrium with a simpler structure and lower potential energy. The risk probability depends on the threshold capacity of the system (resistance) and on the capacity of

Ecological Risk Assessment Through Landscape Science Approaches
2004Risk assessment of landscape biological integrity, associated with ecotypes or ecotype mosaics, is addressed by simple multi-scale conceptual models incorporating metrics related to current human disturbance, based on native species most threatened with extinction and reduction.

Landscape ecological risk assessment study in arid land
SPIE Proceedings, 2007The ecosystem risk assessment is an essential decision making system for predicting the reconstruction and recovery of a damaged ecosystem after intensive mankind activities. The sustainability of environment and resources of the lake ecosystem in arid districts have been paid close attention to by international communities as well as numerous ...

Research Progress on Ecological Risk Assessment Based on Multifunctional Landscape
Journal of Resources and Ecology, 2021The unreasonable utilization and trade-offs of the multifunctional landscape is one of the important causes leading to ecological risk. Quantifying the relationship, heterogeneous process and driving mechanism between landscape function and human well-being can provide a scientific basis for achieving a win-win situation of regional development and ...

Abstract Ecological security patterns (ESPs) aim to provide an effective spatial approach for maintaining urban ecological security based on the relationship between landscape patterns and ecological processes. However, the methods of selecting ecological security sources and evaluating resistance surfaces for ESPs construction are not well developed

Landscape ecological risk assessment and driving factor analysis in Dongjiang river watershed
Chemosphere, 2022The ecological and environmental quality of Dongjiang river watershed has great influence on Guangdong, Hong Kong and Macao. The landscape ecological risk assessment model could effectively monitor and assess environmental quality. In this study, spatial autocorrelation and geographic detector methods were used to explore the spatial characteristics of

Currently, landscape ecological risk (LER) assessment faces issues such as strong subjectivity and limited applicability in ecological zoning. Therefore, this research attempts to optimize the LER assessment model by evaluating landscape vulnerability based on ecosystem services and to conduct ecological management zoning in combination with ecosystem ...
