Tourism Crisis Decision Research Based On The Population Density

Tourism as an emerging industry, gets the vigorously support of the state and the government. The prosperity development of tourism has injected new vitality to our country’s economy. But with the coming era of high risk, in recent years, tourism crisis erupted repeatedly, destroyed the tourism destination image, reduced the confidence of tourists to the tourist destination, also caused huge losses to our country and even the world tourism industry. During the period of tourism crisis, the market regulator is out of control. The best choice to deal with tourism crisis is accurate crisis management strategy. And the determination of tourism crisis is mostly controlled by tourism operators or tourism government department.In order to study tourism crises decision index.The paper according to the impacts of tourism crises, analyzes and summarizes the basis of tourism crises judgement. By understanding tourism crises management case and empirical research results at home and abroad, comparing and evaluating the determination methods and measures of tourism crises case, summed up the judgement index system of tourism crises. Then based on the Analytic Hierarchy Process (AHP), the evaluation index system are subdivision classified by the classification level of general, objective criterion, index layer. Then using MATLAB software to compared each index. The greatest weight is population density. This illustrates the crowd density play a key role in the tourism crisis decision. Finally, combined population density with heat map, the heat map tries to describe the real-time features of population distribution, density and change. Applying it to the Shanghai Bound stampede and contrasting analysis of the importance of population density, and get the population density threshold of determination tourism crisis.The finally conclusion of this paper obtains a population density threshold that used to decide tourism crisis happen or not. The population density threshold can be taken as the basis for determining tourism crisis. Providing more detailed decision for later research groundwork in tourism crises. At the same time, the critical point of tourism crisis can be a reference of tourism crisis early-warning, tour operator can also used it as the standard to control passenger flow volume.
