The study looked at how different plant species in wetlands in the Yinchuan Plain interact with each other. They used various tests to analyze these relationships and found that there were both positive and negative associations among the plant species. The plants were grouped into categories based on their ecological preferences, with mostly positive associations within groups but negative associations between groups. Overall, the wetland plant communities in the Yinchuan Plain were found to be in a state of constant change and not yet stable.
