landscape transformation in Mining Wastelands

Journal of Northeast Agricultural University(English Edition) 2016年第1期23卷 83-88页

Mining provides a wealth of mineral raw materials to human beings, while also causes serious damage to environment and ecology. For decades, landscape renovation in mining wastelands has become a multi-disciplinary research focus. However, compared with the developed countries, China has disadvantages of the relevant theoretical researches developing slowly with lacking supporting technology. According to the design principle of ＂reservation and utilization＂, we reviewed and summarized the methods of landscape transformation in mining wastelands, furthermore, using the way of researching successful cases at home and abroad. In lined with the specific circumstances in China, the target of landscape transformation and basic theories as methods of strategy was developed. Finally, the overall thinking and suggestions were put forward for the development of landscape transformation in mining wastelands.

As a result of socio-economic changes and land abandonment,the main ecological driver of the Carpathian landscape is the progression of the natural forest succession ***,aspects of this process have become worthy of attention,especially in the context of carbon sequestration and the management of protected *** processes,especially within the topsoil,are some of the most susceptible to change,due to the accumulation of organic matter during such land-use *** purposes of this study were to investigate the differences in topsoil development using the A Horizon Development Index(ADI)and to study the composition of humic substances and advanced organic matter humification in different land-use areas in selected Carpathian national parks,***,Magura and Pieniny National Parks in southern ***,a goal of this study was to compare the ADI and the spectroscopic coefficients of humic substances as indicators of the degree of humus horizon shaping as well as advanced organic matter *** total,ten transects were selected,each consisting of three different land-use areas:semi-natural meadow,successional forest and old-growth *** colour was determined in fresh and air-dried samples using the Munsell colour *** air-dried soil samples p H,soil texture,total organic carbon and total nitrogen were *** substances were extracted and further characterized by UV-VIS *** ADI confirmed the influence of natural forest succession on soil colour darkening and the development of the uppermost soil *** analyses of humic substances showed two different patterns depending on soil *** the 0–10 cm layer,natural forest succession reduced the rate of the humification process and decreased the degree of maturity of fulvic acids;in the 10–20 cm layer,it led to an increase in the rate of the humification process and a decrease in the content of humic and fulvic acids at the beginn

The Scramble for LandmSaving the Remains of Rural Space in Switzerland

引用

Journal of Earth Science and Engineering 2014年第10期4卷 612-626页

作者： Walter Leimgruber Department of Geosciences Geography University of Fribourg/CH FribourgCH-1700 Switzerland

In 2012 and 2013, the Swiss population voted on two separate yet related issues concerning spatial planning. In 2012 a restriction on second homes was introduced into the Constitution, in 2013 referendum the planning law was revised. Both issues wanted to restrict disproportionate building activities, and were accepted after a heated debate. This outcome mirrors a change in popular attitude towards constructions in the countryside and so-called ＂cold beds＂（second homes used for a short time only）, but also towards the disfiguration of the （rural） landscape in general. At the same time it revealed two social rifts： between urban populations （that are increasingly migrating towards rural landscapes） and rural regions that want to obtain a similar level of living as the urban majority, and between lowland and mountain regions. The results of the referenda show that the population is very much concerned about the future of our landscape and environment. The paper discusses the two referenda and their implications for Switzerland in general and for regions that are considered marginal. Its focus lies on the political aspects of the two issues, which not only concern marginality but also are a challenge for national cohesion and direct democracy.
