Description

technical field

[0001] The invention relates to the field of research on the distribution of benthos communities, in particular to a method for simulating and predicting habitats of macrobenthos in salt marsh wetlands in the Yangtze River Estuary. Background technique

[0002] The salt marsh wetland in the Yangtze Estuary is an important part of the estuary ecosystem. It exchanges nutrients frequently with land and marine ecosystems and has a complex and changeable environment. It has the ecological functions of supporting vegetation, providing animal habitats, and maintaining biodiversity. As an indicator that can sensitively reflect habitat changes, macrobenthic animals are the best indicators to link the environmental and ecological characteristics of tidal flat habitats. Monitoring and mastering changes in macrobenthos communities can provide scientific basis for the protection of wetland organisms in the Yangtze Estuary, the evaluation of the quality of the benthic envi...
