Abstract：According to the experience of vegetation rehabilitation and the result of ecological safety investigation in the Loess Plateau,the functions and characters of vegetation rehabilitation had been explained,and the core content of vegetation rehabilitation combining the artificial power for promoting vegetation restoration with the natural power of plant community succession is shown in order to achieve that all area vegetation rehabilitation combing with part area vegetation rehabilitation quickly.The aims for the vegetation rehabilitation in the Loess Plateau are that biodiversity increase 10%-15% on average.The coverage of typical species of the geography belt should acheive 20%-25%.The total vegetation coverage should acheive 75%-85%.The soil erosion decrease evidently.At present,the disadvantage for vegetation rehabilitation is no enough research accumulation for technology and the theory of vegetation rehabilitation and ecological efficiency of rehabilitation is not ideal.In the future the key techno-theoretic problems should be solved as quickly as possible by the sketch ideas.The typical demonstration area for vegetation ehabilitation should be set up for comprehensive measurements for rehabilitation.The law and regulation system for vegetation rehabilitation should be formed for the Loess Plateau.
