Research Of The Side Slope Plant Defending Of The Changde-jishou Highway

Along with the rapid development of our country's economy, the highway construction development wasextremely fast in recent years. So the highway's virescence and beautification technology become an importanttopic in the highway design.As a result of the limitation on the technology, equipments and so on, we mostly uses herbage for thehighway's slope design in Hunan. With the herbage's close planting, the circumjacent plants grow difficultly,and then make the effect of the ecology's recovery become worse.In order to cultivate ideal arbor-shrub community and recover the propagation's habitat, promote theplants' transplant, supply location and proper condition for the propagation, and recover steady and consistantecosystem, it is very necessary for us to research the side slope pants' defending. So, this trial intends topropose a complete set of method to the Chang-ji highway side slope's plant protection method, which is basedon the status of Chang-ji highway side slope crag earth geology and the plant distribution, also by studying thedomestic and foreign advanced slope plants' protection technology.This paper follows the ecology succession theory, uses the high tech instruction, the support and synthesisspecialized union investment pattern and so on. This trial researched the composing of the mix-seeds, the plantgrowing matrix and the compounding ways of side slope plants' defending, then we have found several results.The concrete conclusions are as follows:First, the arbor-shrub-grass plants' mix-seeds which are confirmed by the community distributing forms alongthe highway, we have found that would recover the ecosystem and establish the target community.Second, combining the geological situation of the rock and soil along the highway in this project, we haveconfirmed five matrix defending forms: the hydraulic pressure spewing semination, plant seed bags, commonsoil spewing semination, thick-layer material insufflation and the CS granules insufflation. All the above waysare suitable for this project.Third, the defending ways of the hydraulic pressure spewing semination and the improved spewing seminationon this trial are suitable for soil side slope defendiing in this project. However, the ways of plant seed bags, thecommon soil spewing semination, the thick-layer material insufflation, the CS granules insufflation and thecirrus plants defending are suitable for sand side slope defending in this project.
