In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

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.
