湖泊碳循环受到外部因素的影响，这些外部因素控制着质量(如碳、营养)和能量(如光、热)在湖泊过程(如初级生产、呼吸、温室气体排放)上的转移，或者直接或通过陆地景观(Leavitt等人)。2009年；Lapierre等人。2015年)。尽管这些质量和能量的转移应该对所有湖泊产生类似的影响，但在气候、土地覆盖和土地利用不同的地区进行的湖泊碳循环研究表明，湖沼学首要原则的表达程度及其对生态系统功能的相对重要性因地理而异。这一事实可能是由于描述这些对比格局背后的地理因素的空间尺度不匹配(例如气候、土地利用/土地覆盖)，而与单个湖泊生态系统的对比(100‘S-1000’S平方公里vs<；1平方公里；Lapierre等；2015年；CAEL和Seekell 2016年)。从历史上看，对湖泊碳循环的大范围研究超出了个别实验室小组的后勤能力，超出了大多数政府湖泊监测项目的任务范围。然而，来自个别研究和数据综合努力的公开可获取的地理和湖沼学数据越来越多地广泛适用于广泛的环境梯度，以加深对湖泊碳循环的地理模式的理解(例如，Soranno等人)。2017年)。近年来，景观和全球范围的湖泊学受到了越来越多的关注。例如，景观
Lake carbon cycling is influenced by external factors controlling the transfer of mass (eg carbon, nutrient) and energy (eg light, heat) on lake processes (eg primary production, respiration, greenhouse gases emissions), either directly or through the terrestrial landscape (Leavitt et al. 2009; Lapierre et al. 2015). Although these transfers of mass and energy should affect all lakes similarly, studies of lake carbon cycling conducted in regions with contrasting climate, land cover, and land use suggest that how strongly limnological first principles are expressed, and their relative importance to ecosystem functions, vary geographically. This fact may be due to the mismatch in spatial scales that characterize the geographic factors behind these contrasting patterns (eg climate, land use/land cover) as compared to that of individual lake ecosystems (100’s–1000’s km2 vs< 1 km2; Lapierre et al. 2015; Cael and Seekell 2016). Historically, broad-scale studies of lake carbon cycling exceeded the logistic abilities of individual lab groups and were outside the mandate of most governmental lake monitoring programs. However, publicly accessible geographic and limnological data originating from individual studies and from data synthesis efforts are increasingly available for broad extents across wide environmental gradients to develop understanding of the geographic patterns in lake carbon cycling (eg, Soranno et al. 2017). Landscape-and global-scale limnology have received increased attention in recent years. For example, landscape
