Since the policies of the conversion of cropland to forest and the close grazing were carried out,the vegetation quality and coverage rate have been increased all over in Loess Plateau area, the ecological conserving consciousness of ordinary people were strengthened, the environment harness measurements have been optimized, the multiform investments of ecological construction and the urbanization development make vegetation restoration have good future. However, there have been some problems existed such as, the shortage of investment, the government policy instability, the extravagant economic benefit expected, the larger rate of plantation, no enough technological measurements for supporting vegetation restoration and many key theory practice problems that are urgent to be solved, etc. In the future,the goal of near, middle, longterm in the future for vegetation restoration should be clear, the achievement should be expanded, the natural restoration area rate should be increased. The benefit for the household contracted with management should be protected. The investment for research work and inventing ability should be increased.
