Changes in the Spatial Structure of the Landscape of Isolated Forest Complexes in the 19th and 20th Centuries and Their Potential Effects on Supporti…
2020
This study assesses the changes in the spatial structure of the landscape between 1825 and 2019 in the isolated, protected forest complex of the Niemodlin Forests. Based on the analysis of changes in this structure, a change the supporting ecosystem services related to the protection of biodiversity was proposed. The landscape metrics were used separately for the analysis of the structure of the whole landscape, and individual types of ecosystems were used in the research. There were no major changes in the share of individual types of ecosystems during the period under review. At the same time, a very large increase in built-up areas and tree stands was found in 1825. Landscape metrics poi…
Landscape Dynamics in Mediterranean Coastal Areas: Castelló de la Plana in the Last Hundred Years
2019
The littoral areas of the Mediterranean coastline have undergone a significant transformation due to their historical and intense human occupation. The result has been an evolution of different cultural landscape configurations, ranging from those with a marked agrarian character to artificial ones derived from the process of urbanisation and metropolitan growth. The objective of this paper is to define a model to characterise landscape types and units that explains the landscape dynamics (1910-2015) in Mediterranean coastal spaces at local scale, taking as study area the municipality and surroundings of Castelló de la Plana, in Spain. The aim is to identify the way in which society has app…
Landscape Ecological Structure in the Eastern Part of the North Vidzeme Biosphere Reserve, Latvia
2008
Landscape Ecological Structure in the Eastern Part of the North Vidzeme Biosphere Reserve, Latvia Latvia is a country where the forest area has increased and habitat fragmentation has reversed compared with many other European countries. In order to examine the effect of this expansion on biodiversity, vegetation maps dating from 2002 and the years 1930-1936 were used for comparative landscape structure analyses while archive materials from forest plans, and data from the national forest management database were used for land use analysis. Four landscape ecoregions in the eastern side of the North Vidzeme Biosphere Reserve were selected for analysis. Landscape structure indicators derived f…
Le paysage, entre esthétique & écologie : modélisation rétrospective à partir de changements d'occupation du sol
2016
Landscape is both a backdrop to the lives of human populations and a medium for the life cycle of animal species. Landscape changes induced by land-use and land-cover dynamics affect both these dimensions, the one aesthetic, and the other ecological. Because these rationales areusually studied within different disciplines, little research has been done into how the two clashor combine as and when landscape structures change. This work seeks therefore to model the spatial co-evolution of the aesthetic and ecological functions of landscape retrospectively usingspatial metrics based on land-cover data. It focuses on changes in the urban fringes of two French cities (Paris and Besançon) over th…
Applicazione dell’analisi tridimensionale negli studi di Ecologia del paesaggio
2010
Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools t…
Zmiany struktury przestrzennej krajobrazu na obszarze Parku Krajoznawczego "Góry Owawskie" w okresie od XIX do XXI w
2021
Krajobrazy gór i przedgórza podlegają wielu przemianom warunkowanym przez czynniki antropogeniczne oraz przyrodnicze. W Parku Krajobrazowym „Góry Opawskie” i jego otulinie w okresie od XIX do XXI w. doszło do szeregu przekształceń krajobrazowych, związanych z rozwojem sieci osadniczej, zmianami zasięgu kompleksów leśnych oraz zmianami w strukturze upraw. Kluczowe było także objęcie ochroną prawną tego obszaru i utworzenie parku w 1988 r. W artykule dokonano analizy zmian w strukturze krajobrazu z użyciem metryk krajobrazowych, które wykorzystano odrębnie do oceny zmian krajobrazu jako całości oraz poszczególnych klas. Badania przeprowadzono na podstawie obrazów odtworzonych z archiwalnych ź…
Landscape structure, resilience and ecogeographic relations between agro-forestry and forestry landscapes of Sicily: quantitative approaches
2014
Landscape ecology provides a wide spectrum of useful techniques for quantitative analysis of the land-mosaic patterns, on the basis of areal, linear and punctual parameters. According to the scale of analysis, data collection can be costly and time-consuming; this is especially true in areas with a very heterogeneous land-mosaic patterns and landscape-types for environmental variability and cultural reasons. Aims of this work are: 1) to assess the land-mosaic complexity of the traditional agricultural and agro-forestry landscapes (PAfT) of Sicily; 2) to highlight interfaces and structural gradients between main forest areas and closed PAfTs. These aims have the main purpose to pinpoint agri…
Exploring individual preferences for periurban landscapes
2015
International audience; Landscape aesthetic quality has recently become an important dimension of land use policies since it is likely to play a role in human well-being. Several scientific studies have shown that landscape is a significant component of residential satisfaction of inhabitants in urban and suburban areas (Hur & Nasar, 2010; Kweon et al., 2010). Although neglected by land-use planning for decades (Gallent et al., 2004), urban fringes are particularly interesting for analyzing landscape changes. These spaces where town meets countryside (Scott et al., 2013) are indeed particularly concerned with urban sprawl that occurs in all European cities from 1960s (EEA, 2006). Such chang…
