SPECIAL ISSUE： IMPORTANT ISSUES IN MARXIST PHILOSOPHICAL STUDIES IN CONTEMPORARY CHINA：Historical materialism and the path to social actuality

The fundamental task of Marxist philosophical studies today is to uncover contemporary social actuality. It was Hegel who first showed a possible way to social actuality in philosophical terms via sharp critiques of subjective consciousness and its external reflection. Marx critically inherited this legacy from Hegel. His critiques not only undermined the speculative, idealist alliance of Idea and Actuality, but also thoroughly reconstructed the essential dimension of social actuality. A Kantian interpretation of Marxist philosophy on this theme presupposes a dismissal of the dimension of social actuality, which means a return to the philosophy of subjective consciousness. The latter in turn means the actual collapse of historical materialism. The path to social actuality is vital to historical materialism. It is only through this path that the truth of the theory of historical materialism can be upheld.

SPECIAL ISSUE： IMPORTANT ISSUES IN MARXIST PHILOSOPHICAL STUDIES IN CONTEMPORARY CHINA：The essential tension： on the distinction of ideality and actuality in Marxist philosophy

There are two opposing tendencies in the history of Westem philosophy： one is the Platonic- Hegelian tradition that mixes actuality and ideality, the other is the Aristotelian-Kantian tradition that differentiates the two. Marx distanced himself from the former by his critiques of Hegelism, but the later generations have in a sense turned back to it in their interpretation of Marxist theory. Despite its significance, this reversal is fundamentally inconsistent with Marxist philosophy, and will frequently have unfortunate results in practice. Therefore it is of great necessity to clarify the theoretical distinction between Marxism and Hegelism on this issue.

The study of English perfective aspect

Through this research, on the basis of English-Chinese and Chinese-English parallel corpora, the following conclusion tries to be drawn： In English, the perfect may not be used together with the specific time of the past situation. In contrast to English, Chinese does not have perfect constructions. English perfective aspect is an actual aspect indication： duration and completion of an action or situation. According to different reference time, the actual aspect can be divided into past actuality, present actuality and future actuality. This paper will undoubtedly contribute to the study of tense-aspect in Chinese. The study of English perfective aspect is conducive to the comparative study and translation of aspect in English and Chinese.

Forestry ecological footprint in China during 1973–2003

The ecological footprint （EF） model has received much attention as an assessment indicator for sustainable development in recent years. Firstly, the temporal changes of domestic timber production, imports and exports in China were analyzed from 1973 to 2003, the analysis results showed an apparent fluctuation in timber production during 1973-1995 but a decreasing trend during 1995-2002, an increasing trend in timber imports since 1995 especially after the implementation of the Natural Forest Protection Project （NFPP）, an decreasing trend year by year in timber exports since 1995. Secondly, this paper presented a time series analysis of actual forest area demand in the sustainable yield and production approach in China from 1973 to 2003, which includes both import and export forest area demand. The results showed the actual forest area demand simulated from the sustainable yield approach was slightly higher than that from the production approach during 1978-1988 and a little lower during 1989-2003; however, the actual forest area demands simulated by these two model approaches were larger than calculations that expressed in conventional forest EF. Meanwhile, the results indicated the forestry development in China during 1978-1988 was unsustainable due to overexploitation of forest stocking volumes, and China＇s forestry moved toward sustainable development since 1989 because forest resources are exploited at lower rates than they are regenerated. However, compared to forestry developed countries, the forestry development capacity in China is still lower. Finally, based on the model results we analyzed the relationships between forestry EF and the key policies, including trade policy, economic policy and forest conservation programs. In addition, several suggestions about reducing forestry EF and enhancing sustainable forestry development in China are given.

The research of Polar sea ice and its role in climate change

As an important part of global climate system, the Polar sea ice is effccting on global climate changes through ocean surface radiation balance, mass balance, energy balance as well as the circulating of sea water temperature and salinity. Sea ice research has a centuries - old history. The many correlative sea ice projects were established through the extensive international cooperation during the period from the primary research of intensity and the boaring capacity of sea ice to the development of sea/ice/air coupled model. Based on these reseamhes, the sea ice variety was combined with the global climate change. All research about sea ice includes： the physical properties and processes of sea ice and its snow cover, the ecosystem of sea ice regions, sea ice and upper snow albedo, mass balance of sea ice regions, sea ice and climate coupled model. The simulation suggests that the both of the area and volume of polar sea ice would be reduced in next century. With the developing of the sea ice research, more scientific issues are mentioned. Such as the interaction between sea ice and the other factors of global climate system, the seasonal and regional distribution of polar sea ice thickness, polar sea ice boundary and area variety trends, the growth and melt as well as their influencing factors, the role of the polynya and the sea/air interactions. We should give the best solutions to all of the issues in future sea ice studying.

Philosophy of Economic World： Ontological and Epistemological Dimensions

The article is dedicated to the analysis of philosophical understanding of the current economic world. In the existent interpretations of the economic world physical, biological and psychological approaches predominate. They highlight certain important aspects of economic realm, but do not provide a complex global picture of it. The philosophical method used in the article structuralizes the economic world in the context of Aristotelian doctrine concerning economic reality and economic being and Heidegger＇s fundamental ontology. The main attention is paid to the ontological and epistemological aspects of the economic world. The structure of the economic world is considered as a whole and in its dimensions （the economic being, the economic existence, the economic actuality, and the art of economics）. Economic being is considered as a ground, prerequisite, economic background of economic existence. It is resumed that the qualitative analysis of the economic world has to be based on the philosophical, general scientific and economic methodology. Philosophical methodology includes general principles of cognition and categorical structure of science （i.e., structural components） as well as a philosophical knowledge system （i.e., functional components）. General scientific methodology is based on general scientific research principles. It includes all theoretical concepts used to all or the majority of scientific disciplines. Specific scientific methodology, economic methodology use appropriate methods, research principles, and procedures in economics. The art of economics （economic policy） is built on a basis of either the explanatory methodology or applied （engineering） methodology, with its precise tools of statistics, econometrics, and mathematics.
