沿海和内陆水域的可持续管理需要了解旅游和娱乐如何影响生态系统。在这里，我们提出了第一个系统回顾和荟萃分析，以量化休闲船只交通和系泊基础设施对软底淹没植被丰度的影响程度。我们的系统搜索产生了25项研究，其中包含有关船只交通、码头和系泊浮标对植被丰度影响的数据。码头以下的丰度平均为对照组的18%，船舶通行区域的丰度平均为对照组的42%。系泊浮标经常造成没有植被的冲刷区。然而，这些影响是可变的，而且测试这种可变性的原因的研究太少了。我们的结论是，划船会导致水下植被的显著下降，但明智的船只交通管理和改进码头和浮标的设计可以减少负面影响。
Sustainable management of coastal and inland water areas requires knowledge of how tourism and recreation affects the ecosystems. Here, we present the first systematic review and meta-analysis to quantify to what extent recreational boat traffic and infrastructure for mooring affect the abundance of submerged vegetation on soft bottoms. Our systematic search yielded 25 studies containing data on effects of boat traffic, docks and mooring buoys on vegetation abundance. The abundance below docks was on average 18% of that in controls, and areas with boat traffic had on average 42% of the abundance in control areas. Mooring buoys often created scour areas without vegetation. However, the effects were variable and there were too few studies to test the reasons for this variability. We conclude that boating can cause significant declines in submerged vegetation but that informed management of boat traffic and improved design of docks and buoys can reduce negative impacts.
