Vegetation provides potential erosion controland slope protection ,through its hydrological and me chanicalinteraction ofplants withlocalclimate and soil.Thetheoreticalunderstanding ofthese vege tative effectsis the base ofslope eco - engineering .In the pastfew decades,theimportance of vege tation in protecting slopes has been stressed by many researchers.The greater awarenessthat vegeta tion can play a range ofrolesin slope protection has madeitincreasingly a valuabletoolin naturalen vironmentalprotection and civilengineering .and this knowledge hasled to aincreasing application ofvegetation types world - wide .Thoughitisstilla kind ofyoungtechniques,anincreasing amountofexperience ofslope eco - engineering of vegetation is gathering from the past practices,and thelagernumber ofsuccessful examples ofits applicationsis showing its greatfuture .
