自然界的地被植物是当地植物群落自然演替的结果,受当地气候、土壤、水热条件、生物活动所支配.种类组成也是随机的并受种间竞争,适者生存的规律所制约.因而显得杂乱无章、良莠混生、高低不平、色彩不一的野生状态,只能远眺,不可近观,其效果既不能达到人们所要求的某种功能,也无观赏价值.根据某种功能上的要求,因地制宜地选择一定的草种进行人工整齐划—种植的人工草坪,在近代城市绿化中作为改善气候、保护生态环境而日益被人们重视起来.
Ground cover plants in nature are the result of natural succession of local plant communities and are dominated by the local climate, soil, hydrothermal conditions and biological activities. The species composition is also random and controlled by the laws of species competition and survival of the fittest Looks chaotic, mixed, rugged, wild colors of different colors, can only be overlooked, can not be near, the effect can not meet people’s requirements of a certain function, there is no ornamental value .According to a certain function Requirements, according to local conditions to select a certain amount of grass for artificial planning - planted artificial turf, in modern urban greening as improving the climate, protecting the ecological environment and is increasingly being valued.
