Abstract

To determine community characteristics of Vitex negundo var. heterophylla，plant material from three types of typical sites were selected and studied with a 99% confidence interval from a point pattern analysis and with a correlation analysis. Results showed that the V. negundo var. heterophylla population spread stochastically over different stands，except for the Pinus tabulaeformis stand. V. negundo var. heterophylla，was not significantly correlated with Berberis poiretii，Rhamnus parvifolia，Ziziphus jujuba var. spinosa，Ailanthus altissima，and P. tabuliformis. Using a small-scale investigation，V. negundo var. heterophylla was significantly （P = 99%） and positively correlated with Lespedeza bicolor （r＜2.8），Philadelphus pekinensis （1.1＜r＜2.6），Securinega suffruticosa （1.9＜r＜4.2），and Spiraea trilobata （0.8＜r＜1.9）. With a large-scale analysis，V. negundo var. heterophylla had a negative influence on L. bicolor and S. trilobata. Thus，long-term coexistence with V. negundo var. heterophylla was possible for the plant communities above that showed no significant relationship，but V. negundo var. heterophylla would compete for living space with L. bicolor and S. trilobata.［Ch，5 fig. 2 tab. 26 ref.］
