Coastal regime shifts: Responses of community structure, multi-functionality of coastal wetlands to

Spartina alterniflora

invasion

partina alterniflora

invasion is a part of global change. The landwards and seawards invasion in coastal wetlands may lead to the

reduction of the Suaeda salsa and sea grass habitat. The landscape pattern, community structure, species diversity and multi-

functionality of ecosystem were changed greatly in the typical estuarine wetland-Yellow River Delta, China. There were significant

differences in patches’ structure and ecosystem functions from the sea to the land, and there was a significant difference of community

structure, species diversity and ecosystem function between the inner and outer regions of patches. Due to density-structured effect, the

community structure, species diversity and ecosystem multi-functionality represent gradient differences. The evaluation framework

and index system of the impacts of

Spartina alterniflora

on ecosystem multi-functionality were studied, including biological and soil

carbon sequestration, N mineralization, phosphorus retention index, primary productivity, decomposition, sedimentary and so on.

Spartina alterniflora

habitat has a significant contribution to the conservation of species diversity and ecosystem multi-functionality.

It is possibly a new idea or perspective of evaluating the impact of

Spartina alterniflora

invasion from the perspective of ecosystem

multi-functionality.
