, 2021 叶片大小与数量的权衡关系是植物生长策略的基础,研究叶片大小与数量权衡关系的内在机制对于深刻理解植物生长策略具有重要意义。本研究以单个叶片干重表示叶大小,以单位茎上的叶片数量表示出叶强度,采用标准主轴回归分析方法研究呼伦贝尔草原植物叶片大小与数量的权衡关系以及内在机制。结果表明:陈旗嵯岗(典型草原)和陈旗八一(草甸草原)叶片大小与出叶强度存在显著的负的等速生长关系,谢尔塔拉(草甸草原)的叶片大小与出叶强度存在显著的负的异速生长权衡关系 ...

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

政府旅游数据开放的评价指标体系构建与组态分析：基于21个省级行政区的数据
大数据在信息时代和智慧旅游背景下，政府主动对外开放内部的旅游数据，有利于充分释放旅游数据资源的商业价值与社会价值。使用变异系数法与熵权法进行组合赋权，构建了政府旅游数据开放评价指标体系，计算21个省级行政区的具体得分，并采用模糊集定性比较方法进行高评价值与低评价值条件组态分析。结果表明：指标体系包含4项一级指标、17项二级指标与51项三级指标，可以对当前省级行政区的旅游数据开放绩效进行有效评价；利用层、数据层是权重较高的一级指标，法律政策效率与内容、平台关系等是权重较高的二级指标；高评价值组态为综合发展型 ...
