Landscape in the sagas of Icelanders: The concepts of land and landsleg

This article presents a study of the Icelandic landscape concept, and its meaning and embedded connotations. The present-day understanding of the concept provides the point of departure to some of the oldest preserved examples of the term. The analysis thus centres upon the sagas of Icelanders that were written in the Middle Ages. The paper reveals that in the 14th century the concept referred to morphological qualities of land, and was often associated with an aesthetic appreciation thereof. The meaning of landscape as natural scenery has been explained as the outcome of artistic articulations of social relations in the wake of the Renaissance and Romanticism. Such accounts, however, do not explain the aesthetic connotations associated with the Icelandic landscape concept in the Middle Ages, described in this article. The results of the study thus indicate that there may be more to the landscape concept within the cultural domain defined by the Germanic languages than hitherto revealed, particularly in terms of aesthetic experiences of the natural environment. Subsequently, this article emphasises the importance of identifying the culturally embedded meaning of landscape as a concept in the Icelandic context, for successful implementation of the concept in planning practices.

GIS-based Analysis of Temporal Evolution of Rural Landscape: A Case Study in Southern Italy

The apparent features of a rural landscape are the final result of the interaction among several natural and anthropic factors. The analysis of a landscape, as well as the identification of its best management strategies, can be improved when useful information about its modifications along a wide time period is available, so as to assess the effect of the transformations that have taken place there. The implementation within a geographic information system (GIS) of geographical information derived from ancient historical maps, combined with modern digital cartography and recent remote sensing images may provide a very powerful tool for a better-informed analysis and targeted decision-making strategies about the most appropriate rural landscape planning. With the purpose to detect the land use changes in a typical rural landscape in the Basilicata Region (Southern Italy), spatial analysis using free and open-source GIS tools, in which data covering a period of about two centuries, from 1829 to 2017, were implemented. This multi-temporal analysis was carried out to investigate the landscape structure transformations through the assessment of land use change and the implementation of a methodology for the identification of areas in which there has been a natural evolution of the rural landscape. Then, using landscape metrics and spatial analysis tools, some areas in which the landscape has naturally evolved without any anthropic intervention during these 188 years have been identified, and changes occurred on the rural landscape were assessed quantitatively.

伊犁河三角洲景观结构的影响机制研究

在遥感和水文数据的支持下,根据伊犁河三角洲作为典型的中亚干旱区内陆河流域尾闾区域特点,确定了伊犁河三角洲的景观分类系统。通过采用景观结构梯度分析法、景观干扰度指数和景观Kappa指数等方法,系统地分析了近32 a（1975-2007）伊犁河三角洲景观结构的时空演变特征,并对景观结构的影响机制做了充分地探讨。结果表明：（1）沿着一定的地形梯度和水文梯度,伊犁河三角洲流域景观表现出特殊的纵向结构、横向结构的梯度特征和景观内部特征,与地表水直接关联的景观类型表现尤为明显,如湖泊、沼泽、漫滩。（2）在人为活动和自然环境的双重影响下,近32 a伊犁河三角洲景观结构的空间变化具有一定的周期性和不稳定性,主要体现为景观类型面积和空间位置的变化,其中以湿地景观类型的变化最为显著。（3）生态干扰对景观结构的影响因景观类型的不同存在显著的差异性和时空变异性,以湖泊和沼泽受干扰作用最为明显。高、中、低三种干扰强度区域的空间分布及面积变化同样具有一定的周期性和不稳定性。（4）水利工程建设和自然环境是影响伊犁河三角洲景观结构的主要驱动力。水利工程对伊犁河的拦蓄引起景观结构变化的作用最为深远,它通过改变三角洲上游的水文情势直接影响整个区域的景观结构。而自然环境因素中的地形和水文条件主要影响湿地景观类型的时空分布,气候因子则直接影响河川径流量。     

Monitoring directions and rates of change in trees outside forests through multitemporal analysis of map sequences

This study explores the potential of historical maps to detect, measure and monitor changes of trees outside forests. The main goal is to assess local-level changes of scattered trees and orchards and their land-use determinants in two areas in Southern Germany between 1901/1905 and 2009. Firstly, overall landscape changes are recorded. Secondly, the spatial-temporal trajectories of scattered trees and their land-use determinants are identified. Thirdly, changes in quantity and fragmentation patterns of traditional orchards are analyzed in their relationship to overall land-cover change. The results confirm major losses in scattered trees, mainly due to urbanization, agricultural intensification, and land abandonment. They further reveal that, while orchards have persisted in total area, they have undergone critical changes toward a simplified landscape structure and loss of the traditional land-use mosaic, which is a characterizing feature of high nature value landscapes. Multi-temporal assessment showed that most trends have been continuous and did not change directions over time, but rather accelerated during periods of rapid change (most dramatically in the 1950-1990 period). The case of orchards and scattered trees illustrates a major problem of cultural landscapes in Europe: Semi-natural landscape features of high nature value are threatened by both intensification and abandonment of land uses. This makes their conservation a potentially costly enterprise, as both opportunity costs for lost alternative land uses and for conservation management costs arise.     

Early Middle Miocene broken foreland development in the southern Central Andes: evidence for extension prior to regional shortening

Most authors suggest that the main contraction phases in the southern Central Andes started in the Late Miocene. Along the flat‐slab segment, deformation has progressively involved basement and a broken foreland has developed. Recent work suggests that construction of the Andes by late Neogene shortening may have been controlled by lithospheric thinning and crustal structure generated during mid‐Tertiary times in the Southern and Central Andes. Exposures at the eastern border of the Famatina Ranges in western Argentina in the flat‐slab segment document basement involved extension of approximately this age. The Del Abra Formation, the lower unit of a major Andean synorogenic cycle (Angulos Group), reveals a distinct and previously unrecognized early Middle Miocene tectonic event. This is suggested by a 505‐m‐thick thinning‐ and fining‐upward megasequence. Dominantly conglomeratic facies record a continuous progression from fault‐scarp‐related high‐gradient colluvium to relatively distal terminal‐fan facies. The fining–thinning upward megasequence characterizes progressive scarp backstepping and decreasing relief after active extension. Interpretation of the stratigraphic fill and the associated structure (high‐angle hinterland‐dipping fault) favours tectonic inversion of an originally normal fault. This allows reappraisal and new understanding of the early‐stage architecture of the Central Andean foreland. Early Middle Miocene extension may have had an important bearing on the later evolution of the broken foreland.     

Synsedimentary tensional features in Upper Triassic shallow-water platform carbonates of the Carnian Prealps (northern Italy) and their importance as palaeostress indicators

The extensive shallow-water carbonate platform deposits of the Dolomia Principale Formation (Southern Alps, northern Italy) accumulated during the Late Triassic, a time of plate-scale reorganization and rifting. Synsedimentary tensional features such as fractures, neptunian dykes, normal faults, shatter breccias and laterally discordant intraformational breccias have been studied within a well-preserved platform-to-basin transition in the Monte Pramaggiore area (Carnian Prealps). These tensional features follow three preferential orientations: N–S, E–W and NE–SW. To fully explain these different arrays it is proposed that the study area experienced during the Late Triassic the waning rifting phase connected to the westward propagation of the NeoTethys (N–S extension) and the onset of the rifting phase that led in the Middle Jurassic to the opening of the Central Atlantic (E–W extension), with a contemporaneous reactivation of Early–Middle Triassic NE–SW-orientated faults. This palaeostress analysis reveals the good potential of tensional features as reliable palaeostress indicators.

南方“红层荒漠”旅游开发价值分析

“红层荒漠”是一种分布在红层母岩上的特殊土地退化景观,又称为“红层劣地”。其形成过程被称为“红层荒漠化”,指红层区受人为干扰,地表原有的生态结构遭到破坏,在外动力综合作用下,土层快速侵蚀,基岩或其风化壳裸露,土地生产力衰竭的极端土地退化过程。红层荒漠在粤、赣、湘等南方湿润区有较多的分布,荒漠化严重的区域一般是经济欠发达的区域,研究红层荒漠及其合理开发利用具有重要意义。结合多年丹霞地貌的研究成果,认为作为一种旅游资源,红层荒漠具有景观独特、资源稀缺、颠覆常识、生态科普、综合构景等特性,具备很高的旅游开发价值与很强的开发可行性。开发过程中,应当遵循开发服从保护、特色强化、综合效益最大化的原则,重视生态农业旅游和科普旅游等开发方向,可开发成为红层荒漠观光、红层荒漠科教旅游、生态农业示范旅游、红层荒漠山水旅游、红漠乡村旅游以及摄影主题旅游等景区。同时,要注意因地制宜,从资源特点、市场需求、环境保护等实际进行合理的谋划,与周边同类景区错位发展,与邻区其他景区加强联合,实现区域旅游互补发展。

Influence of geothermal energy on the formation of forest in the insular volcanic landscape

A case study is made of the Mendeleev volcano (Kunashir Island, Southern Kuril Chain) to carry out a quantitative assessment of the influence of magmatic energy of an active volcano on the thermal regime of the soil and the ground-level air level as well as on the water balance and forest formation processes in the insular volcanic landscape. It is established that the influent channels of steam-hydrotherms cause an anomalous rise in soil temperature thereby having a substantial influence on the structure and functioning of forest ecosystems. Using a specially developed method, we calculated the geotherm-caused temperature anomalies in the soil. Calculations showed that the forest communities of the Mendeleev volcanic landscape evolved into existence and persist under the same heat and energy conditions as their zonal marginalmainland counterparts. The active volcano compensates for a deficiency in the climatic resource and ensures a stable functioning and a structural configuration of these “climatically unjustified” (extrazonal) island-arc ecosystems. We have empirically substantiated the proposition that geothermal energy of passive volcanoes serves as the factor for acceleration evolution of the insular phytobiota. This constitutes the phenomenon of biogeocenological organization of the volcanogenic landscape in the continent-to-ocean transition zone. It is shown that the magmatic geotherms of the Mendeleev volcano promoted the transgression of species and whole communities from southern areas to this boreal-forest region. We examine the rearrangement of the forest cover toward an increase in its floro- and phytocenotic diversity, the formation of relatively stable boreal-subboreal forest ecosystem with subtropical relicts as well as rudimentary buffer forest communities. It is demonstrated that a geothermal heating of the soil on the slopes and at the foot of the volcanoes of the Kuril Ridge is a large-scale (rather than an exceptional) phenomenon in the hydrothermal regime of forest ecosystems of island-arc ecoregions.     

Stratigraphic evolution of the Triassic–Jurassic succession in the Western Southern Alps (Italy): the record of the two-stage rifting on the distal passive margin of Adria

The Triassic–Lower Jurassic succession of the Southern Alps is characterized by rapid thickness changes, from an average of about 5000 m east of Lago Maggiore to about 500 m in the Western Southern Alps. The stratigraphy reflects the Triassic evolution of the Tethyan Gulf and the Early Jurassic rifting responsible for the Middle Jurassic break‐up of Adria from Europe. The succession of the Western Southern Alps starts with Lower Permian volcanics directly covered by Anisian sandstones. The top of the overlying Ladinian dolostones (300 m) records subaerial exposure and karstification. Locally (Gozzano), Upper Sinemurian sediments cover the Permian volcanics, documenting pre‐Sinemurian erosion. New biostratigraphic data indicate a latest Pliensbachian–Toarcian age for the Jurassic synrift deposits that unconformably cover Ladinian or Sinemurian sediments. Therefore, in the Western Southern Alps, the major rifting stage that directly evolved into the opening of the Penninic Ocean began in the latest Pliensbachian–Toarcian. New data allowed us to refine the evolution of the two previously recognized Jurassic extensional events in the Southern Alps. The youngest extensional event (Western Southern Alps) occurred as tectonic activity decreased in the Lombardy Basin. During the Sinemurian the Gozzano high represents the western shoulder of a rift basin located to the east (Lombardy). This evolution documents a transition from diffuse early rifting (Late Hettangian–Sinemurian), controlled by older discontinuities, to rifting focused along a rift valley close to the Pliensbachian–Toarcian boundary. This younger rift bridges the gap between the Hettangian–Sinemurian diffuse rifting and the Callovian–Bathonian break‐up. The late Pliensbachian–Toarcian rift, which eventually lead to continental break‐up, is interpreted as the major extensional episode in the evolution of the passive margin of Adria. The transition from diffuse to focused extension in the Southern Alps is comparable to the evolution of the Central Austroalpine during the Early Jurassic and of the Central and Northern Atlantic margins.
