Abstract:
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 studid.The results showed that:(1)The overall associations among dominant species in plant community had significant negative association;(2) 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;(3) Based on x2 correction test,together with association coefficient and 3 index in interspecific connection,the interspecific association in 20 principal plant species could be better measured.
