EFFECTS OF INTERACTION BETWEEN NITROGEN INPUT AND ENVIRONMENTAL FACTORS ON COASTAL WETLANDS
Keywords:
Basic disciplines of environmental science and technology, Nitrogen input, Interaction, Control experiment, Coastal wetlandAbstract
The impact of exogenous nitrogen (N) input on coastal wetland ecosystems is complex and uncertain. Taking single factor to double factor interaction as the main line, the impact of single N input and N input interaction with temperature, moisture, and plant invasion on coastal wetland ecosystems was studied, and the research situation and development direction in this field were clarified. The results showed that the effects of single N input and interaction between N input and environmental factors on coastal wetland ecosystems were of three types: promotion, inhibition and no effect. The fitting curves between N input and various indicators of coastal wetlands show three types: linear, nonlinear and invalid. Future research should be based on controlled experiments and focus on the impact of multi-factor interactions on plant populations and community characteristics in coastal wetlands; combine short-term control experiments with long-term fixed monitoring to explore the temporal variation characteristics of plant-soil interactions.References
