These achievements have paved the way for China to enhance the quality and efficiency of growth in the new normal. China＇s future growth prospects are highly correlated with the 13th Five-Year Plan （2016-2020）. For the 13th Five-Year Plan period, China is committed to maintaining an annual growth rate of no less than 6.5%, which is both necessary for China to build an all-round, well-off society before 2020 and consistent with the characteristics of China＇s current economic development stage. Meanwhile, efforts must be made to give prominence to consumption, investment, and export as drivers of growth while continuing to improve labor and capital input and efficiency which is vital to mid- and long- term economic development.展开更多

In the teleportation scheme Bell state measurements （BSMs） are difficult for physical realization, so we investigate another strategy using separate measurements instead of BSM based on cavity quantum electrodynamics techniques. The scheme of two-atom entangled state teleportation is a controlled and probabilistic one. For the teleportation of the three-atom entangled state, the scheme is a probabilistic one. The fidelity and the probability of the successful teleportation are also obtained.展开更多

A principal idea of eavironmental protection and ecological construction is put forward for the 11^th Five-Year Plan pertod： strensgthen the point treatment in key areas and set the main targets based on the idea. The relating countermeasures in national level are proposed as follows： set up appropriate ideas for official achievements by launching resources and environmental cost acconting; adjust the industrial struacture actively by industrial policies and strenuous work; develop circular economy, change the mode of environmental protecgon from end treatment to headstream and proeess control： strengthen the market mechanism in the process of pollution treatment, set up the system of ＂who treats who benefits＂ ; perfect interrelated laws and standards, strengthen the ability of environmental munagement; lay extra emphasis on two key targets： water pollution tretment in key river basins and management of the reserves; and combine the ecological consnuction and poverty alleviation in higher level.展开更多

This paper establishes a framework for nature reserve development that seeks to incorporate ecotourism into its strategies. The overall purpose was to identify the information needs required for a comprehensive nature reserve that incorporates ecotourism related values. It also illustrates the utility of this framework in the context of the Wuzhishan Mountain Region of China. A literature review, the first phase of a visionary strategy and a subsequent gap analysis for available management information were undertaken in order to achieve this paper＇s purpose. Finally, recommendations axe pre-sented for integrating ecotourism into nature reserve development in the Wuzhishan Mountain Region.展开更多
