摘  要:
采用2×2列联表,对衡阳盆地自然恢复灌丛阶段植物群落中20个主要种的种间联结性进行分析,结果表明:自然恢复灌丛阶段群落优势种多物种间显著负关联;群落中重要值较高的20个种群组成的190种对中;有58对呈显著正联结,有34对呈显著负联结;以X2为基础,结合联结系数和种间关联度的3个指标较好地测定了20个主要植物种群的联结性。

摘  要:
Based on 2×2 contingency table, the interspecific association of 20 principal plant species in natural vegetation recovery shrub stage in sloping-land with purple soils in Hengyang Basin was studied. The results showed that: The overall associations among dominant species in plant community had significant negative association. Among 190 pairs of species in higher important values 20 plant populations, 58 pairs were significant positive association and 34 pairs were significant were negative association. Based on X2 correction test, together with association coefficient and 3 indexes in interspecific connection, the interspecific association in 20 principal plant species could be better measured.
