Catchments in the Luquillo Experimental Forest (LEF) of Puerto Rico are warm, wet and tropical with steep elevational relief creating gradients in temperature and rainfall. Long‐term objectives of research at the site are to understand how changing climate and disturbance regimes alter hydrological and biogeochemical processes in the montane tropics and to provide information critical for managing and conserving tropical forest ecosystems globally. Measurements of hydrology and meteorology span decades, and currently include temperature, humidity, precipitation, cloud base level, throughfall, groundwater table elevation and stream discharge. The chemistry of rain, throughfall, and streams is measured weekly and lysimeters and wells are sampled monthly to quarterly. Multiple data sets document the effects of major hurricanes including Hugo (1989), Georges (1998) and Maria (2017) on vegetation, biota and catchment biogeochemistry and provide some of the longest available records of biogeochemical fluxes in tropical forests. Here we present an overview of the findings and the data sets that have been generated from the LEF, highlighting their importance for understanding montane tropical watersheds in the context of disturbance and global environmental change.

Luquillo实验森林：山区热带的集水科学

波多黎各卢奎洛实验森林（LEF）的集水区温暖，潮湿且是热带，陡峭的高程起伏形成了温度和降雨的梯度。该地点的长期研究目标是了解气候变化和干扰状况如何改变热带山区的水文和生物地球化学过程，并提供对于全球管理和保护热带森林生态系统至关重要的信息。水文和气象学的测量范围长达数十年，目前包括温度，湿度，降水，云底水位，穿透力，地下水位高程和河流流量。每周对雨水，穿透水和溪流的化学性质进行测量，蒸渗仪和水井每月至每季度进行采样。多个数据集记录了包括Hugo（1989），Georges（1998）和Maria（2017）研究了植被，生物区系和集水区的生物地球化学，并提供了热带森林中生物地球化学通量的一些可用记录。在这里，我们概述了LEF的发现和数据集，突出了它们对于在干扰和全球环境变化的背景下了解山地热带流域的重要性。
