Abstract: Zhengzhou Yellow River Wetland Nature Reserve is not only one of the most important areas of central wetland biodiversity in our country, but also one of the most typical river wetland. In order to offer better protection to the ecological environment, natural vegetation change under different disturbance had been investigated analysis through the study. The results indicated that the factors affecting the ecological environment mainly include tourism, reclamation and large road &bridge construction, Sand-excavating, firing, and grazing; and man-made disturbance effect of the wetland vegetation is basically negative. All sorts of disturbance, the harm of tourism is lighter. Sand- excavating, herding, influenced vegetation growth strongly. Besides, it will cause the serious degradation; and fire and vegetation will bring the original ecological landscape losses. The Yellow River water reduction pulled down wetland flooded area and frequency, forming the wetland degradation. [Copyright &y& Elsevier]
