Nitrogen cycle in the hyporheic zone of natural wetlands

Nitrogen （N） is one of the most important components and ecological factors for natural wetland ecosystems. It is mainly derived from runoff input, atmospheric deposition, and biological N fixation. The transport and transformation of N in natural wetlands primarily occur in the hyporheic zone （HZ）, a buffer area of intensifted biogeochemical activity that is often regarded as the sink, source, and converter of N in wetlands. The main ways of N attenuation in the HZ are denitrification, anaerobic ammonia oxidation （anammox）, and wetland plant adsorption. The effects of internal and human factors on the N cycle are illustrated in this article. The results indicate that N sources are influenced by human factors such as agricultural activities and fossil combustion, while N attenuation is affected by internal factors, including oxygen concentration, carbon and phosphorus availability, pH and Eh changes, and microorganism actions. Finally, some research trends are provided to get a better understanding of the N cycle in the HZ of natural wetlands. This study may provide a clear perspective of N cycle in the HZ and their interactions between various factors.

基于科研机构的绩效考核系统设计

针对中国科学院绩效考核管理实际情况，本文提出了一种绩效考核信息化系统的设计方案。该系统首先根据组织战略目标构建绩效考核指标体系，然后借用信息化手段将此体系固化到信息系统中，并利用联机分析处理和数据挖掘技术为管理者提供有效的决策信息。实际应用结果表明该系统显著提升了绩效考核管理的效率。
