中文摘要
9806493哈蒙叶和根的分解可以被认为是一个连续的过程,从新鲜的植物凋落物开始,导致越来越难降解的有机物质的形成。这种难熔物质被认为是土壤有机质的前体,从而影响生态系统中的养分供应、生产和碳固存。一个名为LIDET(长期站点间分解实验小组)的团队已经安装了一套实验,以测试大气候和基质质量对叶片和细根凋落物的长期碳和营养动态的影响。这些长期实验涉及16个LTER和其他11个合作地点,总共31种垃圾。这些实验旨在跟踪质量,有机组分和营养物质的变化长达10年。 现在,这项研究已经过了一半,继续提供资金将使数据收集、有机成分和营养成分的实验室分析得以完成。此外,还将通过互联网提供数据。计划是继续原来的设计,并增加一项新的研究,在每一个网站的本地垃圾的化学。这项新的工作将提供一个垃圾化学数据集,这是兼容的LIDET分解数据,也将允许大规模的实验结果的基板质量外推。本研究所产生的数据将被证明是非常有用的,在未来的建模和合成工作。这笔资金还将为调查人员提供时间和资金,以完成这一长期的研究中心间项目。
英文摘要
9806493 Harmon Leaf and root decomposition can be thought of as a continuous process beginning with fresh plant litter and leading to the fomation of increasingly refractory organic matter. This refractory material is thought to be a precursor to soil organic matter, and thus influences nutrient availability, production, and carbon sequestration in ecosystems. A team, LIDET (Long-term Intersite Decomposition Experiment Team), has installed a set of experiments to test the effects of macroclimate and substrate quality on the long-term carbon and nutrient dynamics of leaf and fine root litter. These long-term experiments involve 16 LTER and 11 other cooperating sites, and a total of 31 types of litter. The experiments are designed to follow changes in mass, organic fractions, and nutrients for up to 10 years. Now that the study as passed its half-way point, continued funding will allow the completion of data collection, laboratory analysis of organic constituents, and nutrient content. In addition, data will be made available over the Internet. The plan is to continue the original design and to add a new study on the chemistry of native litters at each site. This new work will provide a litter chemistry data set that is compatible with the LIDET decomposition data and will also allow broad-scale extrapolation of the substrate quality findings of the experiment. The data generated by this study will prove extremely useful in future modeling and synthesis efforts. This funding will also provide the investigators the time and money to complete this long-term intersite project.
