摘　　要：旨在探究秦岭草本植物群落种间关联性。通过野外60个样方对太白县咀头镇黄凤山村地区30种草本植物,测定χ2检验、联结系数(AC)、Ochiai种间关联度指数(OI)等指标。结果表明:在由30个植物物种两两组合而成的435个种对中,AC结果中显著负关联的有301个;OI的结果显示弱联结(0≤OI<0.5)的物种对数是较强联结(0.5≤OI≤1)的5.80倍;χ2联结性检验的结果显示,负关联和无关联的种对数分别占总种对数的21.15%和76.78%。综上所述,该地区的草本植物物种间独立性较强,群落整体处于不稳定状态,仍处于演替阶段。The paper aims to explore the interspecific association of herbaceous communities in Qinling Mountains. Based on 60 field samples, we studied the interspecific association of 30 herbs in Huangfengshan,Zuitou, Taibai by χ2-test, association coefficient(AC), Ochiai index(OI) and so on. The results showed that:among 435 pairs of plant species, there were 301 significant negative correlations in the AC results;the OI results showed that the species pairs of weak association(0≤OI<0.5) was 5.80 times that of strong association(0.5≤OI≤1);the χ2-test results showed that the pairs of negative and non-correlated species accounted for21.15% and 76.78% of the total species pairs, respectively. In summary, the herbaceous species in this area are highly independent, the community as a whole is in an unstable state, and is still in the succession stage.
