An Integrated Spatiotemporal Pattern Analysis Model to Assess and Predict the Degradation of Protected Forest Areas

ISPRS International Journal of Geo-Information, 2020
Forest degradation is considered to be one of the major threats to forests over the globe, which has considerably increased in recent decades. Forests are gradually getting fragmented and facing biodiversity losses because of climate change and ...

Assessing Land Use Conflict in the Yangtze River Middle Reaches Megalopolis for 2030: Integrating Landscape Pattern Analysis and Scenario Simulation to Address Uncontrolled and Severe Conflict Zones

Land Degradation &Development, Volume 37, Issue 14, Page 10513-10531, 30 August 2026.
ABSTRACT Land use conflicts (LUCs) significantly impact regional food security and ecological security. Identifying LUCs helps cut down ecological risks. This study focuses on the Yangtze River Middle Reaches Megalopolis (YRMRM) as a case, employing a landscape pattern approach to construct a land use conflict measurement model.

Análise factorial aplicada a métricas da paisagem definidas em FRAGSTATS

, 2004
Um programa de análise espacial baseado numa grelha de pixeis (FRAGSTATS 3.0) foi usado e os resultados da análise de 50 mapas de ocupação do solo usando esse programa são apresentados. Foram usadas 33 métricas da estrutura da paisagem e investigadas as propriedades das métricas para diversas paisagens (mapas de ocupação de solo de Portugal Continental)

What do We Mean by Environmental Heterogeneity? Toward A Mechanistically Explicit and Scale‐Dependent Framework

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We synthesized 360 studies on environmental heterogeneity (EH) across taxa, regions, and disciplines. Only 10% of studies explicitly defined EH, and definitions were predominantly descriptive. We identify four operational interpretations of EH and propose a Research Roadmap linking EH metrics to five mechanistic hypotheses with testable predictions ...

Linking Grain Planting Patterns to Multidimensional Agricultural Sustainability: Evidence From Landscape Metrics and Spatial Analysis in China

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Changes in grain planting patterns have been closely linked to substantial increases in crop yields. However, their relationships with the Sustainable Development Goals (SDGs) remain unclear, particularly across multiple SDG dimensions. Clarifying these relationships could help inform progress toward food security and the SDGs.
