Study on the Biodiversity Responses to Different Disturbance Gradients in the Wetland of the Yellow River Floodplain Area
Based on the overall vegetation investigation and the usage of the SPSS software,the plant species diversity and community diversity of the wetland in the Yellow River floodplain area (Heigangkou——Liuyuankou) were firstly analyzed in this paper.The landscape heterogeneity of the study area was also quantitatively analyzed by the RS,GIS technology on the basis of the SPOT high-resolution images and the LUCC data.By the comparison of species diversity in different development stages of the wetland (the old floodplain area,the middle floodplain area,the tender floodplain area),and the correlation analysis of the landscape pattern indexes with the wetland community diversity in different spatial scales,the study results showed that the plant species diversity decreased when the human disturbance gradients gradually increased,and the plant community diversities were significantly correlated to the landscape heterogeneity of the wetland.
