A further problem of mass tourism is that created by congestion. The subject of congestion can be considered in three ways. There is first the question of the physical capacity of an attraction to absorb tourists；car parks, streets, beaches, ski slopes cathedrals and similar features all have a finite limit to the numbers of tourists that can be accommodated at any given time. However, a second consideration is psychological capacity of a site—the degree of congestion which tourists will tolerate before the site begins to lose its appeal. Quantifying this is no easy matter since perception of capacity will differ, not just according to the nature of the site itself but according to the market which it attracts.
【正确答案】：大众旅游的另一个问题是拥挤问题。这个问题可以从以下三个方面来考虑。首先是景点接纳旅游者的物理承载力。停车场、街道、海滩、滑雪斜坡、教堂和其它类似地方在某一时间内所能接纳的旅游者数量是有限的;其次是景点的心理承载力。旅游者所能忍受的拥挤程度已使旅游景点开始丧失吸引力。由于心理承载力不仅取决于自然风景，而且还取决于它所吸引的市场，因此各个景点的心理承载力就不一样,这很难用数字的形式表达出来。
