With the development of tourism industry and the exploitation of tourism resources, tourism planning is becoming more and more important in China, and has been identified as a focus of research. However, as it is a relatively new technology, it still lacks systematic analysis on theory, technology, implementation and monitoring, especially on the evaluation technology And the evaluation of tourism planning is actually an important part of tourism planning theory, a high consideration should be given to this point Now in China, most of the evaluations on scenic spot planning are qualitative analysis,with evaluation result being inevitably arbitrary How to solve the problems of evaluating on Master Plan of Scenic Spots through quantitative analysis and decision making in order to select a most suitable plan from multiple choices has become particularly essential This paper set up an "entropy technology based on AHP (Analytic Hierarchy Process)" evaluation model for scenic spot planning First, the weights of each index were obtained through "AHP" method, they were then modified by "entropy" technology, and finally the distance from each plan to the ideal point was evaluated Through this process, we could evaluate which plan is the best with the shortest distance to the ideal point Through three aspects of work, namely, economic evaluation, technological evaluation and environmental evaluation, this paper set up an evaluation index system for scenic spot planning based on 13 indexes chosen Taking Muyan Scenic Spot in Nanjing of Jiangsu as an example, this paper applied the model into the evaluation process, and the result is consistent with the actual evaluation result, indicating the reliability and practicability of the model The "entropy technology based on AHP" evaluation model could turn the qualitative evaluation process into the quantitative process, which provides an opportunity for an objective and a righteous judgment among several plans The authors also pointed out that the limitation of this model is that the index in the model would verify with the characteristic difference of scenic spots,and the parameters may also change in different scenic spots Anyway, this model is a useful exploration means for the scientific, standardized and quantitative evaluation of scenic spots and tourism planning
