Landscape metric is mostly used to quantify landscape patches. However, these patches could also be geomorphological forms, thus using traditional landscape metrics their shape and spatial distribution, or their dynamics could be analysed. The aim of the paper is to study the geomorphological applicability of diff erent indices studying the aeolian forms of Inner Somogy (SW Hungary). In the present research 15 landscape metric indices were calculated with Patch Analyst 5.1 and vLATE 2.0. The negative aeolian forms (blowout depressions and holes) have high number but small size, whilst the positive forms (parabolic dunes and hummocks) have large number and complex spatial structure, thus the negative and positive forms can not be directly connected. The spatial distribution revealed by the applied indices refers to diff erences in moisture content, abundance of sand supply and relief on a regional scale. The negative forms appear in a considerable distance from each other, while the positive forms tend to cluster. Based on the spatial distribution of the forms the matrix could be described as an erosion-transportation zone, and in three accumulation zones the dune size and superimposition increases downwind.

“…These three metrics have been determined to have low collinearity with each other (low redundancy) and also have been used successfully to predict species richness (Lindenmayer et al 2002). As a robustness check, we also calculated the fragment density (km -2 ) by dividing the number of fragments in each parcel by the total area (km 2 ; Table A1.5; for a comprehensive investigation of habitat fragmentation metrics, see Schindler et al 2015).…”

ABSTRACT. Protected area downgrading, downsizing, and degazettement (PADDD) has been documented worldwide, but its impacts on biodiversity are poorly understood. To fill this knowledge gap, we reviewed historical documents to identify legal changes that altered the boundaries of Yosemite National Park. We identified two downsizes and five additions between 1905 and 1937 that reduced the size of Yosemite National Park by 30%. To examine the effects of these downsizing events on habitat fragmentation by roads, we compared protected, never-protected, and downsized lands at three spatial scales using four habitat fragmentation metrics: road density, fragment (land surrounded by roads) area-to-perimeter ratio, fragment area, and fragment density. In general, lands that were removed from protection, e.g., downsized, were more highly fragmented than protected lands and indistinguishable from never-protected lands. Lands where downsizes were reversed were less fragmented than lands where downsizes were not reversed. These results suggest that protected area downsizing may exacerbate habitat fragmentation, a key contributor to biodiversity loss globally. Furthermore, the case study in Yosemite National Park demonstrates that iconic protected areas in developed countries are not immune to downsizing. These findings underscore the need to account for PADDD and governance histories in ecological research, monitoring, and evaluation. As we move toward more evidence-based conservation policy, a rigorous understanding of PADDD is essential to ensure that protected areas fulfill their promise as a strategy for conserving global biodiversity.

“…Human history can be summarized as a history of land use. Land use structure can reflect the allocation and inter-relationship between land resources and human activities in a certain region [2][3][4]. Analyzing spatial structure of land use, we can recognize the correlation between land use and social-economic development, and we can reveal the regularity of the concentration and dispersion of land use distribution, so as to explain regional differences and promote rationality of land use distribution.…”

Land resources and land use activities support the social and economic development in any region. in order to explore the distribution of land use structure, we can apply the Lorenz curves and Gini coefficient to accomplish. In this study, we selected the land use data in 14 prefecture cities in Liaoning Province of China from 2010 to 2015. Based on the Lorenz curve and the Gini coefficient, we analyzed quantitatively the land use structure in 14 prefecture cities of Liaoning province. results indicated that cultivated land, forest land and construction land were evenly distributed, while garden land, grass land and unused land were distributed in a more concentrated state in space scale. On time scale, the Gini coefficient of forest land, garden land and grass land were increasing, and the degree of distribution dispersion has increased, while the gini coefficient of cultivated land, construction land and unused land has reduced, whose distribution tended to equilibrium. Some suggestion for rational land use and structural adjustment has been provided by analyzing the spatial and temporal distribution of land use in Liaoning Province.
