Degradation of High Mountain Ecosystems in Northern Europe

Data material of a long-term high mountain ecosystem research project was used to interpret the grazing impact of reindeers. In central Norway investigations were conducted to both, areas where reindeer grazing is excluded, and areas where intensive pasturing is present for a long period of time.The comparative analysis of grazing impact was based on similar environmental conditions. The results were transposed to northern Norway where dramatic overgrazing had been exceeding the carrying capacity. Using landscape ecological mappings, especially of vegetation and soils, the impact of reindeer grazing in different areas became obvious. Non-grazed lichen-dominated ecosystems of the snow-free locations functioned sensitively near the limit of organism survival. These localities were most influenced by grazing as they offer the winter forage to the reindeers. So, intensive grazing in central Norway led to landscape degradation by destruction of the vegetation and superinduced by soil erosion. Those features were comparable to the situation in northern Norway, where a broad-scale destruction of the environment combined with a depression of the altitudinal belts had occurred due to overgrazing. Functioning principles of intact high mountain systems were explained and used to interpret the environmental background for the understanding of degradation phenomena. Finally, the use of a new model calculating the carrying capacity of high mountain landscape was discussed.

Temperature monitoring from 2012 to 2019 in central part of Suntar-Khayat Ridge,Russia

In recent decades, research of the Alps, Qinghai-Tibet Plateau, and Cordillera have made great progress in understanding the phenomenon of permafrost. For the most part, this has been made possible due to temperature monitoring. However, the permafrost parameters in an area of more than 2 million square km of the mountainous regions of northeast Asia, for the most part, remain a blank spot in the scientific community. Due to the lack and insufficiency of factual materials, in 2012 the P.I. Melnikov Permafrost Institute began to take temperature measurements in the upper part of the permafrost in the central part of the VerkhoyanKolyma uplands, namely the Suntar-Khayat ridge. The article describes the temperature characteristics of air, surface and rocks of the active layer in the range of heights from 850 to 1821 m, in various landscape and topographic elements. For the observation period from 2012 to 2019, we obtained information on temperatures in the soils of the active layer at depths of 1 m, 3 m, 4 m, and 5 m and also air and surface temperature parameters. The availability of data on automated monitoring of rock temperatures in the active layer and the upper horizons of the layer of annual heat rotations made it possible to substantiate the most typical conditions of the temperature conditions of the permafrost zone of the characterized region. The parameters of permafrost existence and development are in favorable conditions. This is shown in the analysis of temperature data of air, surface and active layer. Soil temperatures in the active layer of annual heat rotations are most clearly represented at a depth of 1 m. Currently, on the territory of the mountain regions of Eastern Siberia, there are no more such sites for monitoring the temperature regime of soils. Information on the permafrost parameters in the region will allow us to begin the process of creating new models or checking existing forecasts and the distribution of the temperature pattern. It will also make it possible to evaluate the response of sensitive and vulnerable frozen soils of mountain regions to climate change.

CRWS-mountain Project: Coordinate remediation techniques and devices for water-soil pollution in mountain areas in China

Rural environmental governance is an important strategy to achieve the goal of building "green liveable villages" in China. However, studies on technology and devices for pollution remediation focus mainly on urban areas; in this regard, few studies have focused on rural areas, especially mountainous or hilly areas with interflow. Coordinate remediation techniques and devices for water-soil restoration in mountain areas(CRWS-mountain), a subproject of the "environmental monitoring and remediation in rural areas" project(ERM-rural project), was undertaken to develop techniques and devices for coordinating the restoration of water and soil in rural mountainous and hilly areas with interflow. The CRWS-mountain project will attempt to explore the mechanisms of pollutant transportation and transformation in the interflow-soil-surface water system, establish in-situ and heterotopic remediation systems in landfill, towns and surrounding areas, and construct a comprehensive system for "polluted soilinterflow-surface water" by integrating all the technologies and devices at Yanting, a typical rural mountainous hilly area in Sichuan, Southwest China. We expect that after using this comprehensive system, the water quality will meet the requirements for local water function zoning. The operation cost is 10% lower than that of the existing urban equipment.     

Changing human-environment interactions in medium mountains: the Apuseni Mts (Romania) as a case study

The study of human-environment relationships in mountain areas is important for both theoretical and practical reasons, as many mountain areas suffer similar problems, such as depopulation, unemployment and natural hazards. Medium mountains constitute a special case within mountains, because they are more populated but less attractive as tourist destinations than high mountains. In this context, the Apuseni Mts (Romania) are considered as a case study. In this paper, we apply GIS-based, quantitative methods to characterize the strength and dynamics of human-environment interactions, taking into consideration some environmental factors (elevation, relative height, slope, river distance, lithology, land cover, natural attractions) as well as historical population and recent tourism data. We found that population density has strong (r ²>0.8) relationships with all relief factors (elevation, relative height, slope, river distance), and that best-fit functions are nonlinear. We outlined the varying demographic scenarios by elevation zones and interpreted the historically switching sign of population change versus elevation relationship. We demonstrated that lithology also has an impact on the spatial distribution of population, although it is not independent from the relief effect. The land cover of the mainly cultural landscape is very strongly correlated with relief parameters (especially slope), which suggests good adaptation. We pointed out the dominance of karst objects in the natural tourism potential of the Apuseni Mts and also explored further components of real tourism (spas, heritage, towns). Finally, we concluded that the environmental settings investigated do in fact constrain the spatial framework of society, but socio-economic changes in history can be explained from the side of society, which conforms to the theory of cultural possibilism.

Exploring seven hundred years of transhumance,climate dynamic,fire and human activity through a historical mountain pass in central Spain

A high-altitude peat sequence from the heart of the Spanish Central System (Gredos range) was analysed through a multi-proxy approach to determine the sensitivity of high-mountain habitats to climate, fire and land use changes during the last seven hundred years, providing valuable insight into our understanding of the vegetation history and environmental changes in a mountain pass close to a traditional route of transhumance. The pollen data indicate that the vegetation was dominated by shrublands and grasslands with scattered pines in high-mountain areas, while in the valleys cereals, chestnut and olive trees were cultivated. Strong declines of high-mountain pines percentages are recorded at 1540, 1675, 1765, 1835 and 1925 cal AD, which may be related to increasing grazing activities and/or the occurrence of anthropogenic fires. The practice of mountain summer farming and transhumance deeply changed and redesigned the landscape of the high altitudes in central Spain (Gredos range) since the Middle Ages, although its dynamics was influenced in some way by climate variability of the past seven centuries.     

Geoscience landscape division and tourism zonation in the mid-southern section of the Hengduan Mountains,eastern Qinghai-Tibet Plateau

The mid-southern section of the Hengduan Mountains is a typical region of mountainous landscape in western China and is the core region of "Shangri-La", a world-famous ecotourism destination. The landscape classification system is an important scientific basis for landscape protection and tourism development in this region. By combining geology and geography and referring to the concepts of "system tract" and "tectonic system" in geology, this paper comes up with grading standards for the geoscience landscape system of this region. Based on the regional stratigraphic structure, tectonic fault marks and geomorphological differentiation, this paper comes up with 2 Grade Ⅰ geoscience landscape system tracts, 8 Grade Ⅱ geoscience landscape systems, 21 Grade Ⅲ geoscience landscape areas, and 165 representative Grade Ⅳ geoscience landscape attractions. According to the main classification methods for the geological heritage and tourism landscapes, the geoscience landscapes can be divided into 4 categories, 16 types and 19 subtypes. On this basis, 23 eco-tourism areas of the mid-southern section of the Hengduan Mountains can be delimited. The study provides a theoretical direction and method reference for the geoscience landscape division and tourism zonation, which has an importantsignificance on the mountain landscape protection and tourism development in the regions of complex geo-environments.     

Vegetation geo-climatic zonation in the rocky mountains,Northern Utah,USA

We developed a vegetation geo-climatic zonation incorporating the zonal concept, gradient and discriminant analysis in Wasatch Range, northern Utah, USA. Mountainous forest ecosystems were sampled and described by vegetation, physiographic features and soil properties. The Snowpack Telemetry and National Weather Service Cooperative Observer Program weather station networks were used to approximate the climate of sample plots. We analysed vegetation and environmental data using clustering, ordination, classification, and ANOVA techniques to reveal environmental gradients affecting a broad vegetation pattern and discriminate these gradients. The specific objective was to assess and classify the response of the complex vegetation to those environmental factors operating at a coarse-scale climatic level. Ordination revealed the dominant role of regional, altitude-based climate in the area. Based on vegetation physiognomy, represented by five tree species, climatic data and taxonomic classification of zonal soils, we identified two vegetation geo-climatic zones： （1） a montane zone, with Rocky Mountain juniper and Douglas-fir; and （2） a subalpine zone, with Engelmann spruce and subalpine fir as climatic climax species. Aspen was excluded from the zonation due to its great ecological amplitude. We found significant differences between the zones in regional climate and landformgeomorphology/soils. Regional climate was represented by elevation, precipitation, and air and soil temperatures; and geomorphology by soil types. This coarsescale vegetation geo-climatic zonation provides a framework for a comprehensive ecosystem survey, which is missing in the central Rocky Mountains of the United States. The vegetationgeoclimatic zonation represents a conceptual improvement on earlier classifications. This framework explicitly accounts for the influence of the physical environment on the distribution of vegetation within a complex landscape typical of the central Rocky Mountains and in mountain ranges elsewhere.     

Forest landecape and bird diversity in mountain region, Xishuangbanna, Yunnan

The degeneration of forest landscapes is mainly caused by human impact on the natural environment, which is posing a great threat to biodiversity. We studied the relationship between forest landscapes and birds in mountain regions of Xishuangbanna, Yunnan Province. In Jinuo ethnic region, forest landscape is degenerating, and bird diversity is reducing as a result of human influence. However, in Hani ethnic region of Mengsong area, a comparative study area, there are also traditional practices of agriculture and forestry. The traditional practices are dynamically adaptive to local geographic environment and social economic conditions. A great deal of biodiversity exists in the place where people have lived for many generations and use the resources of environment in a sustainable manner. Considering bird diversity and forest landscape of mountainous area, both economic and ecological benefits should be taken into account, which relate to land use and landscape protection. Biodiversity conservation, resource management and policy making should pay much attention to the best interconnection of land use and landscapes protection.

Changes and development plans in the mountain villages of South Korea: Comparison of the first and second national surveys

Owing to the geographic disadvantages of mountain villages, the social, cultural, and economic conditions of mountain villagers are inferior to those of urban dwellers in South Korea. Thus, in 1995, the The government of South Korea launched a mountain village development support program to promote agriculture and forestry, balance national land development, and preserve cultural heritage. The program was effectively implemented, improving the income, population size, and living conditions of villagers in addition to setting up a system for stable project implementation. However, concerns were raised about long-term development planning, the creation and marketing of specialty brands, facility management/operation, and follow-up support. The government conducted surveys of mountain villagers in 2003 and 2014, obtaining basic data to address these issues. This study evaluates the outcomes of these two surveys, suggesting areas requiring focused action, concentrating on village development projects, forest resource distribution and use, demographic trends, the economy, exchange with urban areas, green tourism, and master planning. We find that despite growth in the forest labor force, forest ownership is diminishing in terms of the number and scale of holdings. Consequently, it is necessary to commercialize forest resources, establish favorable settlement conditions, and expand government support for village-run projects. In addition, systematic forest management for older tree age classes would benefit the public and provide assets for future mountain village development. Our results are expected to provide baseline information for the establishment and efficient implementation of mountain village development policy.     

典型地貌景观指数的多尺度效应分析 ——以山西省运城市为例

 景观指数作为定量描述景观特征的指数,具有明显的尺度效应。进行景观指数的尺度效应研究,对进一步理解格局与尺度之间的关系具有重要意义。本文以TM影像为基础,选择山西省运城市平原、丘陵、山地及综合地貌4种不同地貌类型,对7个常用景观指数进行了多尺度效应分析。结果表明:不同地形上斑块密度(PD)、景观形状指数(LSI)、结合度(COHESION)3个指数有明显的粒度效应,随粒度的增加呈现逐渐减少的变化趋势;最大斑块指数(LPI)、周长面积比分维数(PAFRAC)、景观聚集度(CONTAG)和Shannon多样性指数(SHDI)4个指数随粒度的增加几乎不发生变化。不同地貌的景观指数随幅度的变化规律比较复杂,景观形状指数(LSI)随幅度的增加呈现逐渐增加的趋势,其余6个指数在较小幅度范围内变化比较复杂,但随着幅度的增大有逐渐趋于平稳的趋势。针对研究区不同地貌类型,其景观指数在不同粒度和幅度下有较大区别,可以根据景观指数值的大小来区分地貌的复杂程度。     

Impacts of tourism development on the physical environment of Mussoorie,a hill station in the lower Himalayan range of India

Tourism in mountainous regions is a significant source of revenue generation. However, it has also been associated with many adverse environmental consequences. This study aims at assessing the negative impacts of the incessant upsurge in tourism development on the physical environment of Mussoorie, a well-known mountain tourist destination in India. The impact indicators for the region were identified and assessed by qualitative and quantitative analysis of field observations. The observations indicated the aggravation of traffic congestion, atmospheric pollution, undisposed solid waste, water scarcity and infrastructure unavailability as the prevalent issues, especially during the peak tourist months. The extent of the consequential damage to the environment was evaluated by conducting an assessment of tourism-induced human disturbance on the natural landscape of the town. Slope, slope aspect, vegetation cover, road network and drainage network were incorporated as the determining landscape attributes to prepare thematic maps of landscape quality (perceivable intrinsic properties) and landscape fragility (vulnerability to anthropogenic disturbances) using GIS technique. An absorption capacity map was finally prepared to characterize the study area into regions of different conservation needs. The results identified the need for planning appropriate preservation strategies for different tourist places in the town. The study can be used by the policy makers for implementing the regulatory measures against potential disturbances due to mass-tourism.     

Rocky land desertification and its driving forces in the karst areas of rural Guangxi,Southwest China

With a subtropical climate, Guangxi Zhuang Autonomous Region has a typical karst landscape. Rocky desertification has become a serious environmental issue due to its high vulnerability caused by the joint effect of natural settings and human activities, because of which its eco- environment has been deteriorated in recent years, and farmland has been disappearing sharply at the same time. This, in turn, has exacerbated the poverty level in the rural areas of the region. In this study, we monitored the spatial distribution of rocky land desertification and its temporal evolution using Landsat TM/ETM images of 1985, 1995, 2000 and 2005. We also analyzed the driving forces of the desertification and its expansion. Through constructing regression models by using all the relevant variables and considering the lagged effects as well as fixed effects, we quantified the exact role of different factors causing rocky land desertification in the study area with some new findings. The new findings in this study are greatly helpful for preserving, restoring and reconstructing the degraded mountain environment in Guangxi and other karst areas in Southwest China, and also for alleviating poverty in the rural areas in the future.
