摘　　要：寒地城市因其气候的特殊性,树种之间的关联性较为特殊。以黑龙江省为例,调查常见园林树种的病虫害,并对树种抗病虫害能力进行分析。运用χ2统计量、联结系数分析树种种间关联性;根据相同树种间的负密度制约效应,对树种种内关联性进行研究;结合树种的抗病力得出3组关联性较好的树种,可作为生态园林的基础植物群落。在关联性研究的基础上,对树种的最适多度进行研究,得到2种具有明显优势的树种——白桦Betula platyphylla和水曲柳Fraxinus mandschurica,可作为黑龙江省生态园林的骨干树种。Due to the unique climate in the winter cities, the association among tree species in these cities is special. Taking Heilongjiang province as an example, this paper surveyed the diseases and insect pests of common garden tree species, and analyzed the disease and insect pest-resistant ability of different tree species. In addition, it analyzed inter-specific association of tree species applying χ2statistical magnitude and association coefficient, and conducted research on intra-specific association of tree species as per negative density restriction effect on the same tree specie; and obtained three groups of tree species with good association and strong resistance to disease, which can be used as the basic plant communities of ecological garden. On the basis of association research, it conducted research on the optimum abundance of tree species, and obtained two tree species with significant advantages-Betula platyphylla and Fraxinus mandschurica, which can be used as the dominant tree species of ecological garden.
