Effect of the shrub on neighbor flowering plants

Description/ Question/ Methods The experiment was performed to determine if the <em>Dodonaea viscosa</em> shrub size and proximity has a positive (facilitative) or negative (competitive) affect on the abundance of nearby flowering-plant species. The experiment took place on shrubs present under powerline corridors south of York University. Each shrub was numbered and a number generator app was used to determine the order in which the shrubs were measured. The size of each shrub was accounted for by measuring the height, length and width of the shrub. The end of measuring tape was placed on the main stem and measured up till five meters south of the shrub. The soil thermometer was placed at each marked distance (1m, 3m &amp; 5m) to measure the soil temperature. At each marked distance, the 1m x 1m quadrant was placed to determine the count of flowering plants according to the species present in the quadrant. A total of 39 shrubs were measured through the three day period.

实验描述/研究问题/实验方法：本实验旨在探究车桑子（Dodonaea viscosa）灌丛的个体大小与空间邻近程度，对周边开花植物物种丰富度产生促进（正相互作用）或抑制（竞争）影响。实验于约克大学（York University）南侧电力走廊下方的灌丛中开展。首先为每株灌丛编号，并通过随机数生成应用确定灌丛的测量顺序。通过测量灌丛的高度、冠长与冠宽以表征其个体大小。将卷尺零端固定于灌丛主茎处，沿南侧方向测量至灌丛外5米位置。在标记的1米、3米及5米距离处分别放置土壤温度计，以测定对应位置的土壤温度。在每个标记距离处布设1m×1m样方，统计样方内各开花植物物种的个体数量。本次实验周期为3天，共计完成39株灌丛的测量工作。
