摘要本文着重介绍了厄瓜多尔帕拉莫和山地林区水资源系统的经济和生态价值，并根据最近的文献综述，描述了控制降雨径流过程的机制以及土地利用的变化如何改变这种变化。审查显示，现有的理解是片面的，是个人和孤立研究努力的结果，并因缺乏长期完整和一致的数据集而受到阻碍。现有的知识还不允许对调查结果进行放大和缩小。文章最后(1)列举了阻碍对热带安第斯生态系统的水文学了解的一些主要差距，(2)提出了加快了解和制定政策和措施的建议，以保证厄瓜多尔热带安第斯地区脆弱的水生态系统的生态安全和可持续发展。
Abstract This article highlights the economic and ecological value of the water resource systems of Ecuador's páramo and montane forest region and gives a description, based on a survey of recent literature, of the mechanisms controlling the rainfall–runoff process and how changes in land use alter the transformation. The review reveals that available understanding is partial, the result of individual and isolated research efforts, and is hindered by a lack of long-term complete and consistent data sets. Available knowledge does not yet permit up- and downscaling of findings. The article concludes by (1) citing some of the major gaps that impede hydrological understanding of the tropical Andean ecosystems and (2) proposing recommendations to speed up understanding and development of policies and measures to guarantee ecologically safe and sustainable development of the fragile water-based ecosystems of Ecuador's tropical Andean region.
