Opis:
The key objective of the study is to analyse structural characteristics of the landscape from the viewpoint of the structure’s durability, characteristics and speed of change. The research focused on the area surrounding Płock. In the analysed period (1987-2010) slight changes were detected with regard to the land cover, though they were significant in terms of the natural environment. No single dominant process determining land cover change was identified. Fluctuations prevailed (producing a slightly different picture in each microregion), with a fixed pattern maintained. Distribution, shape and spatial location of land cover types are only partly determined by land lie and habitat quality. Fragmentation of the terrain is relatively high, which reflects intense land use, at the same time indicating opportunities to preserve the wildlife and vegetation typical for agrocenoses.

Opis:
At present, geoecology-related discussions are focused on the ability to provide systematic and universal landscape description in a variety of space and time scales, as well as in different functional systems. This requires the development of landscape schemes in the form of hierarchical structural and functional systems. This paper has therefore focused on concepts of crucial importance for landscape system description, such as scale, spatial range and structure and landscape functioning. The definition of these concepts and their characteristics are crucial for the ability to describe a landscape system, in terms of its structural and functional composition and valuation, as well as assessment of landscape and ecosystem functions and services. Therefore, the analysis allows a demonstration of approaches discussed in the subject literature and the authors’ opinions.

Opis:
The goal of this study is offer a deep understanding of the landscape dynamics in the Gorgan Township, the Golestan Province, Iran. Landsat satellite imagery of two different time thresholds, i.e. the years 1992 and 2011, was acquired from the US Geological Survey database and the changes were quantified for the Gorgan area covering a 19-year time span. Furthermore, an integrated Cellular Automata-Markov Chain (CA-MC) model was applied to predict future changes up to the year 2030. We used the intensity analysis method to compare the historical dynamics of different land categories at multiple levels. The results indicated that during the 19 years, the built-up and forest areas increased by 2.33% and 0.27%, respectively, while agriculture and remnant vegetation decreased by 2.43% and 0.24%, respectively. The CA-MC model illustrated that in the following 19 years, the built-up areas could increase by 2.45%. An intensity analysis revealed that forest gains and losses were dormant while remnant vegetation gains and losses were active. The built-up area’s gains and water bodies’ losses were active and stationary during both time intervals. The transitions from water bodies and remnant vegetation to agriculture were regularly targeting and stationary, while the transition from forest to agriculture was regularly avoiding and stationary. Our findings also indicated a heavy systematic transition from agriculture to built-up areas. Regarding the increasing population growth and urbanisation in the region, the outcomes of this study can help make informed decisions for the management and protection of natural resources in the study area.

Opis:
In this study, land use/land cover (LULC) changes were identified in AngYai Village, Sikhottabong District, Vientiane Capital, Laos, from 2015 to 2020 using the Geographic Information System (GIS) and remote sensing (RS). Topographic maps and Google Earth Pro satellite imagery data were used with ArcGIS 10.8 software to map land use fluctuations. The study area was classified into the six main types of LULC (agricultural, builtup, forest, main roads, waste land, and water bodies) based on field research, geographical conditions, and RS data. The results indicated sizeable increases in the built-up, main roads, and especially waste land areas over the study period. The forest and agricultural land areas decreased during the study period, possibly due to increased urbanization rates, nomadic cultivation, and indiscriminate deforestation in the study area. The river area was affected by the construction of hydroelectric dams and by the climate, leading to the drying up of water sources and causing water body areas to decrease to some extent.

Opis:
The concept of catena in landscape surveys is used to demonstrate the surroundings of landscape units, their vertical structure and inter-unit processes, as well as the mosaic nature of the landscape. Furthermore, it reflects the structural and functional heterogeneity of the surveyed area, at the same time indicating types of links between landscape units, depending on a variety of geological, habitat-related and biotic conditions, including land use and its transformation arising from anthropopressure. The catena survey performed included four key morphological and lithological units with varied landscape structure and functioning: glacial upland, vast outwash plains, the Wisła River valley and deepened channel valleys, as well as dune hills and hillocks. The results prove that the functioning of landscape systems depends on the forms of land use and their durability. Characteristics of leading components in catenas are diverse despite a similar genesis of landforms and relief shaping processes.

Opis:
A mountain landscape is characterized by a highest dynamics resulting from a diversified shaping, natural values, changeable conditions and individual characterological features of the observer. The phenomenon of space-time continuum and the velocity of the changes occurring while moving about in the area are of a great significance for the dynamics of the mountain landscape. These transformations of the mountain landscape find their reflection,and influence numerous forms of life and culture. For a long time it has been observed in art, especially in painting and literature, which shaped the conventional canons of beauty and the manners of environment perception. In the mountains they created fashion for particular threads or forms of folklore. The dynamics of the mountain landscape is influenced by existence of very strong aspects of the 'third dimension' i.e. drops expressing themselves in daring forms of shape. The dynamics is stressed by contemporary phenomena connected with more and more rapid transformations resulting from economic and social processes. Unfortunately, these changes are of decidedly destructive character and, by introducing for example contemporary, very aggressive dominants, often bring about irremediable loss in the natural elements and spectacular values of mountain landscapes.

Opis:
The aim of the work is to develop a method of landscape dynamics under anthropogenic impact. The developed methodology is tested on the territory of Kostanay region, which is one of the main regions of mining industry development, with a focus on iron ore mining and crop production. Space images and field survey results are used as input materials. In general, the work consists of the following six stages: the first stage includes the selection and processing of space images, the second stage includes the calculation of indices based on data from different channels of space images, the third stage includes field work aimed at collecting information for verification of the obtained results on the basis of RS data, the fourth stage includes the calculation of range values, the fifth stage comprises verification of the obtained indices, and the final sixth stage deals with calculation of the integral index of landscape degradation degree and analysis of landscape dynamics under anthropogenic impacts. The calculation of the integral indicator of the degree of degradation of the natural environment of the Kostanay region, based on the degradation of each indicator in the conditions of anthropogenic impact, allowed for identification of landscapes with different degrees of degradation (from weak to very strong). The research confirmed that landscapes with a high degree of degradation under anthropogenic impact are confined to semi-desert landscapes in the south of the study region. The degradation of these landscapes is associated not only with anthropogenic impacts but also with natural and climatic features that influence the development of landscape pollution processes. On the contrary, landscapes with a weak degree of degradation correspond to the forest-steppe and steppe zones, characterized by a high level of economic development and resistance to anthropogenic impacts. The verification of the obtained indicators by the values of the remaining 25% of field points determines the reliability of the obtained results, ranging from 87% to 92%, confirming the correct choice of methods and techniques for obtaining the results, especially the choice of field methods and vegetation and non-vegetation indices for assessing the selected indicators. Subsequently, based on the verified map of degradation of the natural environment, created through space monitoring for a certain period, it is possible to forecast the functioning of the natural environment in the conditions of anthropogenic impact.

Opis:
The objective of this paper is to present the effects of general changes in land use in recent decades on plant cover structure in Poland. The paper is focused on spontaneous processes that occur in agricultural and forest areas being no longer under human pressure. Studies carried out in different geobotanical regions of Poland demonstrated that the directions and range of dynamic changes in plant cover are similar across the country. The formation of secondary forest phytocenoses, on the lands delivered from human activity is a common ecological process observed today in the agricultural landscape. In the dynamics of forest vegetation the basic process is regeneration after ceased use, and the introduction of legal protection.
