Le point sur les fonctions des corridors et les processus géomorphologique de perturbation des corridors : couloirs des avalanches de neige et coulées boueuses.
The paper discusses main theoretical and methodological assumptions regarding designation of ecologicalcorridors and determination of their boundaries. It presents a review of concepts of ecologicalcorridors prepared in Poland and draws attention
to the lack of legal instruments, which would ensure ecological network continuity. The paper discusses the state and scope of works on the implementation of the concept of the Lublin Ecological Network in updated spatial development plan of the Lublin
Dans le cadre de la gestion du territoire, des notions comme celles de flux d'individus et de corridors servent à décrire l'organisation et la structuration des populations animales. Un corridor est défini pour un type particulier d'espèce. Les AA

This paper, through a theoretical and conceptual analysis, offers a critical reflection on ecologicalcorridors as an innovative means of the environmental and land planning, aiming at combining the ecological requirements with those of development

Besides the investigations into the basic elements of the ecological spatial networks : the ecological matrix areas, corridors of barriers and also the biocores and buffer zones, the analysis of the edge-zones, the so-called ecotons
, is an increasingly popular topic of landscape ecology. The ecological role of the edge zones is proportional to the contrast between the ecological properties of the areas they separate. The ecological contrast is the sharpest possible round the town outskirts. - (ZK)

are introduced. On this basis, the study brings forward the method of ecological footprint and capacity prediction. Models and methods are employed to calculate EF and EC (ecological capacity) in 1995 and 2000 and predict them in 2005 in Hexi Corridor (northwest
The ecological footprint (EF) is a kind of concise method of quantifiably measuring the natural capital consumption and it can reflect the goal of sustainability. In this paper, the concept, the theory and method of ecological footprint

A propos de la gestion des corridors fluviaux, l'A. montre comment revaloriser les savoirs humains anciens, voire ceux qui ont disparu. Le génie écologique, aujourd'hui à la mode, réinvente des techniques traditionnelles. Une meilleure exploitation
In the late 1970s, a concept of an ecological network in former Czechoslovakia, called the Territorial System of Ecological Stability (TSES) was formulated as a response to large-scale natural and semi-natural habitat fragmentation and loss
. In the Czech Republic, the TSES concept is a part of the environmental legislation. The whole system is the network of ecologically significant segments of landscape, efficiently distributed on the basis of functional and spatial criteria, covering biotic
, hydrological, soil and relief conditions. It consists of biocentres, corridors and buffer zones and is established at 3 hierarchical levels : local, regional and national.

Here, the AA. propose that the control of sediment erosion and deposition by riparian vegetation is a key geomorphological and ecological (i.e. biogeomorphic) function within fluvial corridors. In a 3 year study, they investigated the correlations

through visually interpreted Landsat TM images of 1989, 1996 and 2005. It is believed that there were a series of landscape ecological problems caused by city expansion. For this reason, this study adopted accumulative cost distance model, combined
with ecosystem services and spatial interactions of landscape types, analyzed the spatial difference of the ecological function and the compactness of landscape structure in the study area, and further discussed the landscape pattern optimization proposal

Extreme damage was caused by wave and wind erosion on sand dunes on the Baltic coast near Palanga in Lithuania. Waves breached a wide ‘corridor’ or ‘blowout’ through the coastal sand dune. A progressively widening breached blowout developed
