Emerging Issues in Tropical Ecohydrology; June 5-9, 2016; Cuenca, Ecuador

热带地貌约占全球陆地面积的五分之一，产生了地球上大部分的径流，并影响着全球和区域气候。此外，由于气候变化和森林砍伐，热带景观正在经历快速变化。这些变化在一系列尺度上对水和生物地球化学过程的影响是巨大的，但人们对此知之甚少。本次查普曼会议将考察目前对热带生态水文学的理解，并确定热带系统的关键研究需求。本次查普曼会议的主题是“热带生态水文学中的新问题”，会议将在厄瓜多尔的休卡举行，为期三天的会议和一天的实地工作。专题将包括：(1)生态系统退化和恢复的影响；(2)将植物生态生理反应与流域水文学联系起来的生态水文学方针和技术；(3)与跨尺度和跨生物群的水平衡的机械评估有关的新概念(例如，分布式建模)；(4)测量植物和溪流水通量的新技术(例如，稳定同位素、树枝年代学、树干径流、遥感、涡流协方差、分布式建模)；以及(5)在生态生理学家和生态水文学家之间建立明确联系的方法。会议将产生一系列综合文件，列出热带生态水文学研究的关键问题，并为解决最紧迫的生态水文学研究需求制定一项协调一致的战略。

Tropical landscapes account for about one-fifth of the global land mass, produce most of the Earth's streamflows and influence global as well as regional climates. Additionally, tropical landscapes are undergoing rapid changes due to both climate change and deforestation. The effects of these changes on water and biogeochemical processes, at a range of scales, are large but poorly understood. This Chapman Conference will examine current understanding of tropical ecohydrology and identify critical research needs in tropical systems.This Chapman Conference on "Emerging Issues in Tropical Ecohydrology" meeting will be held in Ceunca, Ecuador with three days of meetings and one day of field work. Themes will include (1) the influence of ecosystem degradation and recovery; (2) ecohydrological approaches and techniques for linking plant ecophysiological responses with watershed hydrology; (3) new concepts related to mechanistic assessment of the water balance across scales and across biomes (e.g., distributed modeling); (4) new techniques for measuring plant- and stream-water fluxes (e.g., stable isotopes, dendrochronology, sapflow, remote sensing, eddy covariance, distributed modeling); and (5) methods for building explicit linkages between ecophysiologists and ecohydrologists. The conference will result in a set of synthesis papers that lay out critical questions for ecohydrological research in the tropics and a cohesive strategy for addressing the most urgent ecohydrology research needs.
