Measurement and analysis on the perception of the residents engaging in tourism industry and its impact
从事旅游业者对旅游影响认知水平的测量

To study residents' perception toward tourism impact is of practical significance for developing tourism industry.Taking Luya Mountains Nature Reserve as a case,the background characteristics of the residents engaging in tourism industry and the perception toward 27 indices about tourism impact are investigated on the spot,and the relationship between their characteristics and the perception level is analyzed by two-way indicator species analysis(TWINSPAN) and detrended correspondence analysis(DCA) in the paper.The results show that:(1) TWINSPAN is a kind of better classifying way,and can divide 32 samples into mature and active group,immature and active group,retreating group and apathy group.(2) Each group has its own distribution area and borderline on the DCA ordination figure.Axis 1 of DCA reflects the samples' sex and income mainly,and Axis 2 shows their education level.(3) The distribution pattern of dominant factors decides on the distribution pattern of the samples' groups to a great extent.(4) The classification of TWINSPAN needs to combine with actual fact,and DCA can eliminate "arch effects" obviously.The result of TWINSPAN is consistent with that of DCA,and both are comparable.Both can show the ecological relationship between the residents engaging in tourism industry and their perception toward its impact objectively.However,it still needs farther studies on how to express their interrelationship more directly.
