The application principles of the Mongol-Yuan culture in the landscape elements are found out,through the research on the meaning of Mongol-Yuan culture and the connectivity between culture and landscape elements.The application of the Mongol-Yuan culture is specified by a typical design case analysis so as to offer some references for the modern landscape design.The Mongol-Yuan culture can be applied to the modern landscape elements,such as landform,architecture,sculpture,paving and so on.And the artistic conception of the Mongol-Yuan culture can be created by the application of the Mongolian totem culture,characteristic style,featured pattern,local customs and so on. 展开更多

With the rapid development of digital technology,new forms of digital capital and transnational capitalism have emerged under the manipulation and utilization of capital.Digital capital is composed of intangible and intangible products in labor.It is like traditional capital,which completes capital accumulation from the exploitation of surplus value,that is,data and information begin to operate as a new capital.With the renewal of technology,the form of labor has evolved from material labor to non-material labor and then into digital labor.Digital technology is not limited by time and space,which leads to transnational information sharing and transnational capitalism.However,alienation and exploitation always exist in digital labor.According to the unique characteristics of digital labor,the time and place of exploitation have undergone tremendous changes,and the time boundary between rest and labor has also become blurred.The scope of exploitation coverage is further expanded. 展开更多

China's eastern area is at middle and later stage of industrialization during which the relation between urban and rural areas, industry, and agriculture appears maladjusted. The main problems are shrinkage in agricultural comparative earning and lack of driving force of agricultural development. Based on calculating agricultural labor productivity in east China from 1996 to 2005, this paper analyzes contributing degree of motive forces of agriculture develop in ten provinces and cities of east China applying GCA (Grey correlative analysis). The results show that there is no absolute correspondence between the level of industrialization and agricultural labor productivity in China's eastern area. There is no synchronous development between industry and agricultural labor productiviry in some areas. Fertilizer and agricultural machinery input had high contributing degree for ten years; however; contributing degree in land and irrigation work input was low. Non-materialization inputs became the leading role in most provinces and cities' increase of agricultural labor productivity. Modern agricultural development need non-materialization inputs as primary motive force, at the same time, direct material input and facility input as guaranteed function. For some reasons, agricultural development is characterized by "more direct material input, less facility input " in east China now. Optimal driving.force model of future agricultural development in east China is that non-materialization inputs are dominant, that perfected facility input arc guarantee, and that certain substance inputs are necessary 展开更多

Global climate change and the accelerated melting of glaciers have raised concerns about the ability to manage ice-snow environments.Historically,human ancestors have mastered the ecological wisdom of working with ice-snow environments,but the phenomenon has not yet been articulated in cultural landscape methodologies that emphasize“nature-culture relevance”.The challenging living environment often compels indigenous people to form a strong bond with their surroundings,leading to the creation of long-term ecological wisdom through synergistic relationships with the environment.This ecological environment is conceptualized as a cognitive space in the form of the landscape,with which the aboriginal community norms and individual spirits continually interact.Such interactions generate numerous non-material cultural evidences,such as culture,art,religion,and other ideological aspects of the nation.These evidences symbolize the intellectual outcome of the relationship between humans and the landscape,and they create the“spiritual relevance”through personification and contextualization.The aim of the study is to explore the traditional ecological wisdom of the Inuit people who live in the harsh Arctic,and analyze the Inuit’s interaction with the landscape through the lens of“associative cultural landscape”,and decode the survival experience that the Inuit have accumulated through their long-term synergy with the Arctic environment.The findings focus on the synergy between the Inuit and the ice-snow landscape,examining the knowledge and ecological wisdom that the Inuit acquire from the ice-snow landscape.Our goal is to develop a perspective of the ecological environment from the viewpoint of aboriginal people and establish a methodology,model,and framework for“associative cultural landscape”that incorporates ethnic non-material cultural evidences.From the results,a total of nine models for interpreting traditional Inuit ecological wisdom are generated based on the“diamond model”of“associative cultural landscape”,covering the transition from the physical landscape to a spiritual one and demonstrating the associative role of the landscape in stimulating potential spiritual cognitive abilities in humans. 展开更多
