An International Training Workshop on Tropical Soil Properties and Hydrology Linked to Existing Forest Dynamics Projects; Barro Colorado Island, Panama; September 2003

0314581危害这项美洲计划的奖金将支持一个关于热带森林的结构和动态如何与其所处环境的物理特性相关联的研讨会。这次会议是由路易斯安那州立大学的凯尔·哈姆斯博士与巴拿马巴尔博亚史密森热带研究所的克里斯蒂安·桑珀博士合作组织的。讲习班将汇集来自美国、欧洲和八个热带国家的研究生和高级研究人员，学习和交流技术，目的是描述已经建立的用于森林多样性和动态长期研究的研究地块的土壤和水文特征。该研讨会将为一项正在进行的由美国国家科学基金会资助的研究项目做出贡献，该项目由史密森尼热带研究所的热带森林科学中心（CTFS）协调，该项目试图将树木多样性与热带土壤、气候和其他物理因素的全球变化联系起来。目前在CTFS协调的网络内有15个大型森林动态监测地块，拟议的讲习班将使人民和地理区域参与整个项目的人数增加一倍以上。讲习班活动将包括：(1)关于热带森林养分循环和水文的理论和背景的夜间讲座和非正式讨论；(2)探讨了土壤资源测量的实验设计和采样技术；(3)在巴罗科罗拉多现场进行关键土壤和水文分析的实践；(4)讨论和开发各种新的测量方法和方案，这些方法和方案可以由每个站点的当地合作者独立进行，成本低廉。因此，拟议的讲习班将促进许多国际参与者参与项目的设计，将确保所有场址的数据收集遵循一套统一的方法，并将促进进一步的跨场址比较。

0314581HarmsThis Americas Program award will support a workshop on how the structure and dynamics of a tropical forest are related to physical properties of the environment in which they occur. The meeting is being organized by Dr. Kyle Harms of Louisiana State University, in collaboration with Dr. Cristian Samper of the Smithsonian Tropical Research Institute in Balboa, Panama. The workshop will bring together graduate students and senior researchers from the United States, Europe, and eight tropical countries to learn and exchange techniques aimed at characterizing the soils and hydrology of research plots already established for long-term studies of forest diversity and dynamics. The workshop will contribute to an ongoing NSF-funded research project coordinated by the Center for Tropical Forest Science (CTFS) of the Smithsonian Tropical Research Institute that is attempting to link tree diversity with global variation in tropical soils, climate and other physical factors. There are now 15 large-scale forest dynamics monitoring plots within the network coordinated by CTFS and the proposed workshop will more than double the participation of people and geographic regions in the overall project. Workshop activities will consist of: (1) evening lectures and informal discussions on the theory and background of nutrient cycling and hydrology in tropical forests; (2) Discussions of experimental design and sampling techniques to measure soil-borne resources; (3) Hands-on practice of key soils and hydrological analyses at the Barro Colorado site; and (4) Discussion and development of a variety of new measurements and protocols that could be carried out inexpensively, and independently by local collaborators at each site. Thus the proposed workshop would promote the involvement of many international participants in the design of projects, would ensure that data collection at all sites follows a unified set of methodologies, and would catalyze further cross-site comparisons.
