群植由二、三十株以上至数百株的乔、灌木成群配植时称为群植，这个群体称为树群，树群可由单一树种组成亦可由数个树种组成。树群由于株数较多，占地较大。在园林中可作背景、伴景用，在自然风景区中亦可作主景。两组树群相邻时又可起到透景框景的作用。树群不但有形成景观的艺术效果，还有改善环境的效果。在群植时应注意树群的林冠线轮廓以及色相、季相效果，更应注意树木间种类闾的生态习性关系，务以能保持较长时期的相对稳定性。
Group planting is called group planting when there are more than 20, 30 or hundreds of trees and shrubs in groups. This group is called tree group. The tree group can be composed of a single tree species or several tree species. Due to the large number of trees, the area of trees is large. It can be used as background and companion in gardens, and as main scenery in natural scenic spots. When the two groups of trees are adjacent to each other, they can also play the role of penetrating and framing. The tree group not only has the artistic effect of forming landscape, but also has the effect of improving environment. In order to maintain the relative stability for a long period of time, we should pay attention to the contour of canopy line, the effect of color and season, and more attention to the relationship of ecological habits of species among trees.
