摘要
通过对哈尔滨城郊防护林物种丰富度、多样性、均匀度等指数的测量和计算，研究了哈尔滨城郊防护林物种多样性，结果表明，哈尔滨城郊防护林带的物种多样性指数较低，不同样带之间差异不大；物种多样性指数分布范围为1．625～2．402，平均值为2．041。物种均匀度也较低，样带之间差异不大，介于0．596～0．807之间，平均值为0．706。
Richness,diversity, evenness of species of protection forest in Harbin suburb were determined and calculated. Species diversity of protection forest in Harbin suburb were studied. The result shows that index of species diversity of protection forest belt in Harbin suburb is very low. There is no difference among different transects. The distribution range of species diversity index is 1. 625-2. 402. The mean value is 2. 041. The evenness of species is also very low. There isn＇ t any difference （0.596-0.807） among different transects. The mean value is 0.706.
