So the characteristicsof farmland area in Shandong Province during the Qing Dynasty (1644-1911) are summarized firstly: 1)the rising trend of farmland area was striking; 2) farmland area had remarkable fluctuation; 3)farmland area per capita decreased dramatically; 4) wasteland reclamation index increased rapidly.Then, the driving forces of farmland area change are analyzed. It is concluded that natural andhuman factors are jointly influential. Among the driving forces, human dimensions are the mainfactors of farmland area change, which direct the general tendency of the changes mentioned above.And the natural factors influence the stability of farmland area as well. Variation of the naturalfactors would act as the major contributory factor to farmland area change during years or periodsof abrupt climatic changes, or during the intensive occurring periods of natural hazards. Besides,the passive aspects of human factors, such as war chaos also influenced the fluctuation of thefarmland area. This research indicates that it is feasible to study the land-use/cover change byChinese historical literatures, which has huge potential to provide a comprehensive picture of thegrowing dominance of human land-use and land-cover patterns that can be used in many global changeresearch projects.展开更多

The historic facts have witnessed the influence of scientific research progress on the development of television art. In this paper, the author intends to reveal some phenomenal facts which are known by very few people, namely, the first ever appearance of electronic television in Uzbekistan. This paper gives us some authentic and valuable historic materials for the invention and development of television set in the world.展开更多

Although our country＇s social security system has made great development and progress, but it still does not adapts the level of economy development, especially compared with the requirements of the people. Based on the principle of Marx＇s ＂real man＂ theory and combine the ＂real man＂ with the ＂people oriented＂, this article discussed the basic framework of the present social security system and its shortcomings in China. Then I try to put forward suggestions from breaking the urban-rural dual structure, gradually establishing urban and rural areas as a whole one of social security system, actively expanding the social security fund financing channels, establishing a nationwide unified social security of personal accounts, strive to establish a ＂people oriented＂ social security system.展开更多
