This work is devoted to the study of land resources transformation that was caused by human activity. The subject of study is to assess and forecast physical land and soil degradation, associated with the technical intensification of hazardous exogenous processes. The research is based on the use of methods of ecologic-geomorphological analysis, mathematical-statistical modeling and forecasting. This project gives characteristics to the main anthropogenic factors of threats and risks to land and soil, which take place in the territory of Ukraine. The estimation was conducted relatively dangerous hydrological and geological processes that are key factors of physical degradation of resources. These processes include erosion, flooding, secondary waterlogging, landslides and other collapsed phenomena. Graphic models reflect specific factors and environmental consequences of the most dangerous exogenous processes. Predicted is the development of dangerous hydrological and geological processes, influenced by technogenic factors. Different scenarios of physical land degradation are developed by the example of a specific technonatural geosystem. A measurement system of the sustainable usage and management of soil condition in Ukraine is improved.展开更多

Due to the dual attributes of cultural industries, the openness of cultural industries has demonstrated special features globally. To promote the development of China＇ s cultural industries, the effort should be paid to transfer culture resources into cultural products, to distinguish the responsibility of government and market, to integrate the value chain, to diversify revenue sources and to foster open environment.展开更多
