| Abstract: | The study was conducted in the Yellow River Delta Wetland(YRDW). The purpose of this study is to investigate the spatial characteristics of vegetation and soil factors, so that the coupling relationship can be applied in different wetland landscape types. The results indicated that farmland and wetland vegetation were the two largest landscape types in YRDW, occupying about 46.87% and 20.6%. They provided abundant biomass and vegetation coverage, as an important supplement for wetland blue carbon. In addition, spatial distribution characteristics of soil factors was determined by landscape types. The annual average available phosphorus(AP) was in a state of deficiency, at grade Ⅳ standard, and the highest content in the farmland;the annual average available potassium(AK) was in a medium state, at grade Ⅳ standard and the highest content in the bare area. Finally, there was a significantly negative correlation between effective potassium and Shannon-wiener index, which became the main controlling factor in plant growth and zeroing. |
