概要	Tourism carrying capacity assessment estimates the maximum level of visitor use a destination or site can sustain before its environment, infrastructure, host community, or visitor experience begins to deteriorate unacceptably. The concept, given its influential tourism formulation by A. M. O'Reilly in 1986, recognises that carrying capacity is not a single number but a set of limits operating across distinct dimensions — physical and ecological capacity on the resource side, social capacity on the host and visitor side, and economic capacity on the activity side — with the binding constraint being whichever is reached first. Carrying capacity is the conceptual engine behind Butler's Tourism Area Life Cycle, explaining why unmanaged growth leads to stagnation, and it underpins much of sustainable destination management even as it has been refined into more flexible, indicator-based frameworks.	The Tourism Area Life Cycle (TALC), introduced by Richard Butler in 1980, models a destination as evolving through a recognisable sequence of stages, much as a product moves through its life cycle. Plotted as visitor numbers against time, a typical destination traces an S-shaped curve running from exploration, through involvement, development, consolidation, and stagnation, after which it faces a fork: decline, or rejuvenation. The model's central message is managerial — as a destination grows it approaches its carrying capacity, and the deteriorating physical, social, and economic conditions that follow stagnation are not inevitable but depend on whether managers intervene in time. Butler's paper, published in the Canadian Geographer, became one of the most cited frameworks in tourism studies precisely because it links a destination's growth trajectory to the resource-management decisions that determine its fate.
