Analysis on the Relation between the Species Richness of Crown Spider Community and the Plants Number Investigated in Citrus Orchard
【摘要】 柑橘园树冠蜘蛛群落物种丰富度(S)与调查株数(q)之间的关系式为:S=2,280q0.787,经X2检验,理论数与观察数之间具较高的吻合度.柑橘园树冠蜘蛛群落调查的“最小株数”为9株.
【Abstract】 This article deals with the relation between the species richness of crown spider community and the plants number investigated in citrus orchard. The result shows that they have such a formula as;s = 2. 280q0.787,by X2-test,there is a better goodness-of-fit between the theoretic value and real value.
