The historical factors of the development of organic agriculture in the Baikal region are considered on the basis of ethnoecological experience of traditional agriculture management in the 18th–19th centuries. It is pointed out that the historical method of developing the territory of Transbaikalia is based on nomadic ethnic culture, self-consciousness of the Buryat ethnos, and on the stereotype of behavior in the natural environment and constitutes a unique historical experience of adaptation of the Buryats in the steppe and forest-steppe landscapes of Transbaikalia. And the preservation of nomadic traditions and the Buryat culture of economic managing deserve the attention of researchers. The historical-geographical approach makes it possible to demonstrate the adaptive character of nomad livestock breeding and the use of the territory of Transbaikalia region by the Buryat ethnos in the past, using a conditionally allocated cattle-breeding model as an example. It is shown that the livestock husbandry (nomadic) model of agrarian nature management under consideration reflected a specific “strategy of adaptation” of traditional (nomadic) nature management to the natural environment of the region, which was at a certain socio-economic level of development and represented a natural model for the existence of the Buryat ethnos formed under the influence of the unique landscapes of Transbaikalia and historical traditions. The livestock husbandry model of the economy in the past was the main system of using the territory of Transbaikalia by the Buryat population and reflected the dynamic stereotype of behavior in a given natural environment. The main features of nomadic livestock husbandry are identified, which confirms that the livestock husbandry model was an ecologically correct form of farming, and traditional agriculture is an alternative to intensive forms of agriculture, a kind of management with a focus on the manufacture of ecologically clean products of livestock husbandry as well as being the prototype of organic agriculture in the Baikal region.  相似文献

This paper provides an overview of the documents on the preservation and sustainable use of natural resources within the Lake Baikal drainage basin. An analysis is made of the results of the environmental activity during the period of planned economy and post-perestroika. In the reform years, Baikal was included on the List of the World Natural Heritage Sites, the Federal Law “On the protection of Lake Baikal” was adopted as well as three federal target programs of the protection of the lake and socioeconomic development of the Baikal natural territory. Due to funding shortages, however, they are hardly implemented. The latest legal acts substantially restrict the rights of local residents to land privatization, the development of the social infrastructure, and to use natural resources. Furthermore, in spite of a large number of federal nature conservation directives, closure of many enterprises and reductions in emissions, the ecological situation on Lake Baikal is not improving. Among the problems is the negative attitude of local residents toward the restriction of their constitutional rights to property and economic activity. In addition, all ecological legislative acts are adopted without any public discussion and funding of environmental protection expenditures is not a priority. An improvement of the ecological situation on Baikal is possible only through a further development of the region’s environmentally safe economy and by raising the living standards of the local population on the principles of sustainable development with due regard for the interests of future generations.  相似文献

In order to estimate the present-day pollution levels in the ecosystem of the Selenga River Delta and to monitor the changes caused by the discharge of household refuse and industrial wastes,as well as the functioning of the agricultural and stock farming,a comprehensive study of the water and bottom sediments in the main branches of the Selenga River Delta was carried out.This study has determined the concentrations of heavy metals in river water and bottom sediments in its delta.  相似文献

The paper reports newly obtained data on the granulometric and mineralogical composition of bottom deposits in branches in the Selenga River delta and on the distribution of metals in various granulometric fractions and along the length of an branch of the river in the delta. It was determined that carbonates precipitate as a solid phases in the Kharauz branch, the most copious stream in the delta, and the metals are concentrated in the sand fraction. The bottom deposits of the minor Kolpinnaya branch are characterized by the accumulation of Mn oxides of variable composition, a mixture of colloidal or poorly crystalline minerals (most commonly, pyrolusite). Most of the metals are concentrated in the pelite fraction.  相似文献

This article-one of the results of a unique expedition of sub ocean manned vehicles “Mir-1” and “Mir-2” on the lake Baikal. The Author of the article took part in 10 dives to depths of up to 1600 meters, during which he for the first time discovered the ancient layers of gravel material. The origin of these layers was associated with wave-cut activity in the early days of filling the lake basin. These underwater terrace-good indicators of a four lap increase in lake level, which corresponds to the stages of melting of continental ice formations in North Asia.  相似文献
