Abstract
Based on stratified random selection method,investigate the number and characteristics of the community in Jiamusi.The results showed that: there were 169 vascular plant species.Diversity showed that species richness index(S) :herb layer shrub layer tree layer;Shannon-wiener Index(H) and Simpson's diversity Index(D) show the same,as herb layertree layer shrub layer;Pielou index(J)shown as tree layershrub layerherb layer.Recommendations for future maintenance of green plant to enhance the process of tending to increase the introduction of shrubs,and promote the improvement of species diversity.
