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.

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，热带景观正在发生迅速变化。这些变化对水和地球化学过程的影响，在一系列尺度上，是巨大的，但知之甚少。 本次查普曼会议将审查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。本次关于“热带生态水文学中的新问题”的查普曼会议将在厄瓜多尔的Ceunca举行，为期三天的会议和一天的实地工作。 主题将包括（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法和技术;（3）与跨尺度和跨生物群落的水平衡机制评估有关的新概念（例如，分布式建模）;（4）用于测量植物-和溪流-水通量的新技术（例如，稳定同位素，树木年代学，树干液流，遥感，涡度协方差，分布式建模）;（5）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论文，阐述热带地区生态水文研究的关键问题，并提出一项解决最紧迫的生态水文研究需求的连贯战略。
