Abstract: Based on the research of vegetation restoration and construction for swamps of different degree of interference,the results showed that the effects of natural vegetation restoration on shrub and herbaceous marshes under burning and grazing intermediate disturbance were good. According to the growth indexes,it only needed 2 or 3 years for degraded ecosystem to recover to the un-disturbance status by the herbaceous plant restoration measures,but it took longer time with the shrub plant restoration measures. According to the comparative analysis of 5 artificial species,the preserving rate of Hippophae rhamnoides,Caragana microphylia and Hemerocallis citrine was 100%,88.23% and 62.15% respectively in their own patterns. But the preserving rate of Amorpha fruticosa and Medicago sativa were zero after years of artificial vegetation restoration. The order of different patterns of artificial species disposition model as follows: the mix disposition model of Hippophae rhamnoides and Caragana microphylia>Hippophae rhamnoides and Hemerocallis citrine>Caragana microphylia and Hemerocallis citrine. In order to use the results of these kinds of artificial species disposition models and techniques for degraded ecosystem vegetation engineering restoration,these models and techniques should be tested under different degraded ecosystem of marsh and different scenario conditions.
