Therefore, what the natural tourism projects should first be ＂the economic value of the natural resources＂. However, after the man-made planning and being given the humanity, they have the ＂economic value of the human resources＂. In the construction of the future path of the development, we should also have the dynamic study on the subjective preferences of the Chinese consumers. The change of these subjective preferences directly results from the change of the levels of their own income.展开更多

Beijing＇s mountainous areas depend on the background and orientation of ecological economy for sustainable development. It is of great significance to explore the development of the circular agriculture in the mountainous areas to facilitate sustainable use of agriculture resources. Beijing＇s mountainous areas have accumulated considerable experiences in boosting the circular agriculture. By summarizing the modes of circular agriculture in mountainous areas and analyzing their actual practices, the paper proposes we need to give high priority to strengthening publicity efforts, giving full play to resources advantages of mountainous areas, and establishing a management mechanism and operation mechanism to promote the development of circular agriculture in Beijing.展开更多
