生物多样性在路域植被养护中的应用

公路路域植被进入养护期以后，管护的经费开始减少，而植物演化刚刚开始，如还是按照原来的管护方式，势必造成植物群落的逆向演替，使其有可能再次回到裸露状态。因此，需要从生态学的原理出发，利用生物多样性对现有的群落进行改造，使其形成一个结构合理、稳定、防护效果突出的植物群落。

Discussion on Using Biodiversity in Maintaing the Plant Community Among the Road

It is important to improve the plant community when the time of the maintaining come,because the outlay to maintain it has reduced and we can't do it by the way that we had done before.If there are no suitable measures to improve it,the succession of community will opposite the way it should be.The plant community maybe return to the state of the bareness.It maybe been improved to form a plant community of possessing suitable structure,stabilization and safty by using the biodiversity.By it we can reduce the cost of maintaining the plant community.
