摘要
植物学研究不仅历史悠久,而且对于当前生态学研究意义重大。作为最佳研究手段的野外实验,现有的方法存在不具有普遍性和伪重复的风险,且时间、人力和成本上无法负担,需要采取"全球多(站)点野外实验"的新思路。因为具体解决了明确的科学目标和问题、拥有关键团体、可辨识的处理和采样、简单和不昂贵的设计、良好的数据管理计划、确保参与科学家的明确收益以及为额外的研究预留空间等7个要素,营养网络及其提出的分布式协作实验(协议)获得成功,但也存在站点类型和实验设计的限制、周期的伪重复和范围的局限的不足。
The botanical research has the long history and is of great significance to current study of ecology and global issues.As the best research way,current method of field experiment takes the risk of nonuniversality and pseudoreplication,and furthermore,it cannot burden the consumptions of time,human resource and cost.Thus,the new approach of global multisites field experiments（GMFEs）becomes a necessity.Nutrient Network’（NutNet）and distributed collaboration experiments（DCEs）（protocol）,proposed by NutNet,have achieved success because of its 7 keys of developing clear scientific goals and questions,owning key group,identical treatments and sampling,simple and inexpensive design,good plan for data management,ensuring clear benefits for participating scientists and reserving room for additional studies.Meanwhile,the new approach has the shortages of limitation of type of sites and design of experiment,pseudoreplication of period and confinement of range.
