Visitor use surveys and water quality data indicates that high visitor use levels of two rivers in Puerto Rico does not appear to adversely affect several water quality parameters. Optimum visitor use to maximize visitor defined satisfaction is a more constraining limit on visitor use than water quality. Our multiple regression analysis suggests that visitor use of about 150 visitors per day yields the highest level of visitor reported satisfaction, a level that does not appear to affect turbidity of the river. This high level of visitor use may be related to the gregarious nature of Puerto Ricans and their tolerance for crowding on this densely populated island. The daily peak visitation model indicates that regulating the number of parking spaces may be the most effective way to keep visitor use within the social carrying capacity.
游客使用情况调查和水质数据表明，波多黎各两条河流的高游客使用水平似乎并未对若干水质参数产生不利影响。与水质相比，为使游客定义的满意度最大化而进行的最佳游客使用量对游客使用构成了更具限制性的限制。我们的多元回归分析表明，每天约150名游客的使用量能带来游客报告的最高满意度水平，这一水平似乎不会影响河流的浊度。这种高游客使用量可能与波多黎各人的群居本性以及他们在这个人口密集岛屿上对拥挤的容忍度有关。每日高峰访问模型表明，调节停车位数量可能是将游客使用量控制在社会承载能力范围内的最有效方法。
