0227642HarmonThis is a three-year project submitted by Dr. Mark Harmon, Oregon State University, in collaboration with Dr. Hen-Biau King, Taiwan Forestry Research Institute, to conduct a comparative study on decomposition of 15N-labeled fine roots and fate of N releases in Western Oregon, USA and Taiwan LTER sites. Root decomposition is a fundamental process in forest ecosystems. Understanding of fine root decomposition and its N dynamics is important in understanding controls over soil strength maintenance, soil organic matter formation, ecosystem N cycling, and ecosystem responses to disturbance and climate changes. This cross-site comparison project between the U.S. and Taiwan can contribute significantly to International Long-Term Ecological Cooperation, and provide a valuable research experience for U.S. students. This project is jointly supported by the National Science Council of Taiwan and NSF.

0227642 Harmony这是一个由俄勒冈州州立大学的Mark Harmon博士与台湾林业研究所的Hen-Biau King博士合作的三年计划，旨在对美国西部俄勒冈州和台湾LTER站点的15 N标记细根分解和N释放的命运进行比较研究。 根系分解是森林生态系统的一个基本过程。 细根分解及其氮素动态的研究对于理解土壤强度维持、土壤有机质形成、生态系统氮素循环以及生态系统对干扰和气候变化的响应具有重要意义。这项美国与台湾的跨地点比较项目，将为国际长期生态合作做出重大贡献，并为美国学生提供宝贵的研究经验。 本计画由台湾国家科学理事会与NSF共同赞助。
