查询词典 emission spectrum

The paper includes the following parts: The first chapter is the introduction, which discusses the background of the title, research actuality, research significance, research methods and the whole research thinking and frame. The second chapter simply reviews the idea of "hard/soft ecotourists" spectrum, combining the characteristics of ecotourism market and the disadvantage situation of the Nature Reserve ecotourism, points out the necessity of the study on ecotounst behavior. The third chapter analyzes the external and internal influence factors of ecotounst behavior, which gives the matting for the after paper. The fourth chapter is the focal point of the thesis, carries on the discussion of the ecotourist behavior characteristic, and takes the Yellow River Delta Nature Reserve for example to investigate and study ecotourists.
