旅游业是当今世界经济的主要收入来源之一,但是旅游业在危机面前较为脆弱,会影响如游客数量、航班数量、宾馆入住率、交通、商务活动、投资等。同时,自然灾害、政治动乱和军事冲突是目前影响旅游下滑的重要原因。因此,各国都应该重视预防危机的预警机制,力求减少灾害对旅游带来的负面影响。 Tourism is one of the major sources of income in today’s world economy. However, the tourism industry is vulnerable to the crisis and will affect such factors as the number of tourists, the number of flights, hotel occupancy, transportation, business activities and investment. At the same time, natural disasters, political turmoil and military conflicts are the major reasons for the current decline in tourism. Therefore, all countries should pay attention to the early warning mechanism for preventing crises and strive to reduce the negative impact of disasters on tourism.
