Foreign publications devoted to the problems of determination and valuation of ecosystem services and their practical application in planning economic activities are under review. This direction of studies is being rapidly developed. It was clearly shaped after the global Millennium Ecosystem Assessment performed in 2005 on the initiative of the United Nations. In the recent decade, this direction has got an official status; specialized journals have been founded; regular conferences and workshops have been conducted. The number of publications in this field has increased considerably. The contribution of soil scientists to the valuation of ecosystem services remains modest. It is argued that the assessment and valuation of the ecosystem services of soils is a promising direction for soil science. Ecosystem services are subdivided into the groups of provisional, regulating, cultural, and supporting services. The latter group is considered the natural basis ensuring the efficient performance of other ecosystem services with their direct or indirect impact on human well-being. The assessment of ecosystem services implies three major directions: ecological, economic (monetary), and social. For each of the groups of ecosystem services, specific methods of their economic valuation are applied. Thus, provisional services are mainly assessed according to their market values. The contribution of provisional services to the total value of ecosystem services is relatively small. Regulating services are often estimated by the avoided cost and replacement cost methods, and cultural services (recreation, inspiration source, aesthetic value, spiritual value) are valued by the travel cost method. The methods of nonmarketable valuation are essentially based on the willingness-to-pay approach. Upon valuation of ecosystem services at the local level, a systems approach should be applied; it is necessary to taken into account cooperation bonus obtained by the particular stakeholders. It should also be noted that the removal of additional pressures from ecosystems in a given place might result in the increase of the anthropogenic loads on ecosystems in other places. The separation, mapping, and valuation of ecosystem services are performed with an ultimate goal to ensure sustainable development of the society and human well-being. The ecological and economic approaches in this field are actually aimed at strengthening of the role of market mechanisms in the environmental protection policy.
в обновлении с целью отразить накопленные за последние десятилетия сведения о почвах, реальные изменения в почвенном покрове, включая результаты антропогенной трансформации почв, обеспечить топографическую точность карты и ее увязку с материалами космических снимков. Концептуальной основой обновления содержания карты является субстантивно-генетическая классификация почв России
Поступила в редакцию 12. 09.2018, после доработки 12.09.2018, принята к публикации 15.11.2018 По-контурный анализ содержания Почвенной карты РСФСР масштаба 1 : 2.5 млн (1988) и ее перевод в формат классификации почв России (КПР), как первый этап работы по созданию новой почвенной карты страны, показал необходимость введения ряда уточнений и дополнений в КПР. Они касаются определений и наименований диагностических горизонтов и признаков (так, предложено заменить название перегнойно-темногумусового горизонта AH на перегнойно-гумусовый), введения новых признаков (cro -надмерзлотная аккумуляция органического вещества), расширения списка подтиповых характеристик без их "жесткой" привязки с выделенным типам. Эти изменения направлены на то, чтобы иметь возможность адекватно отразить в КПР накопленные сведения о разнообразии почв России, которые в максимально полном (для страны) виде представлены на Почвенной карте РСФСР и введены в Государственный реестр почвенных ресурсов России. Ключевые слова: почвенная карта РСФСР, субстантивно-генетическая классификация почв России, диагностические горизонты, диагностические признаки
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
