我们提出了一个定量的文献综述，以评估在何种程度上与植物的田间实验已经解决了问题的竞争模式在时间和空间上，竞争的后果，社区结构，物种之间的竞争能力的比较。我们概述了必要的治疗比较和统计分析来回答每个问题，然后描述了符合这些标准的实验数量及其结果。虽然我们在89项研究中发现了101个实验，但其中63%的实验仅涉及竞争是否会显著影响单个物种在单个时间和地点的个体适应度的某些组成部分。尽管有限的数据库，以解决更复杂的问题，竞争的相互作用，我们确实发现了一致的结果，我们审查的一些问题。在测试中，竞争总是有显着的影响分布格局（五个实验），相对丰度（两个实验），和多样性（四个实验），与竞争的概念，社区结构有很强的影响一致。另一方面，种内竞争通常不强于种间竞争的竞争效应（四个实验）或响应（三个实验），这表明资源分配可能不是一个重要的机制共存的植物。
We present a quantitative literature review to assess the extent to which field experiments with plants have addressed questions about patterns of competition over time and space, consequences of competition for community structure, and comparisons of competitive ability among species. We outline the necessary treatment comparisons and statistical analyses to answer each question and then describe the number of experiments that meet these criteria and their results. Although we found a total of 101 experiments in 89 studies, 63% of these experiments only addressed whether competition significantly affected some component of individual fitness of a single species at a single time and site. Despite the limited data base to address more complex questions about competitive interactions, we did find consistent results for a few of the questions we reviewed. Where tested, competition always had significant effects on distribution patterns (five experiments), on relative abundances (two experiments), and on diversity (four experiments), consistent with the notion that competition has strong effects on community structure. On the other hand, intraspecific competition was not usually stronger than interspecific competition for either competitive effect (four experiments) or response (three experiments), which suggests that resource partitioning may not be an important mechanism of coexistence in plants.
