A study on ecotourists’ behavioral characteristics in Beijing: a case study in Baihuashan nature reserve;

This paper based on an effective classification of ecotourists and general tourists,we conducted a thorough comparison of the characteristics between the ecotourists in Baihua Mountain and general tourists from several perspectives.

Therefore,it is important to identify ecotourists from visitors to protected areas.

Based on an investigation of motivations and behaviors of Chinese and foreign eco-tourists,this paper made a comparative analysis of the differences between the two groups.
