Recently, human activities become frequently that lead to the eutrophication, the destruction of marine
habitat, the degradation shallow sea ecosystem and the growing recession of biological resources in shallow
sea. Traditionally, the eco-restoration mode of shallow sea wetland was limited to single bioremediation
technology. Base on the theory of ecological restoration, the idea about the essential facility and key technology
on the restoration of shallow sea wetland habitat and the conservation of biological resources in shallow
sea were put forward in this paper, so as to provide the reference to marine habitat restoration and conservation
of biological resources in China. Shallow sea wetland was chosen as the research subject and technical
route of ecological restoration and reconstruction in the region of shallow sea wetland was proposed in the paper.
Three measures, including water quality restoration, habitat construction and protection of marine biodiversity,
were proposed to guarantee the stability and development of the shallow sea wetland ecosystems. The
details of technical routine were that to do background investigation on water resource, substrate conditions
and biocenosis of shallow sea wetland; to carry on diagnostic analysis of wetland condition according to the
relative factors of shallow sea wetland resources which were got in the status survey; to judge the status and
extent of wetland degradation; to propose more effective ecological restoration and reconstruction technology;
to find the restriction factor and determine the reasonable ecological restoration target according to the diagnosis;
to propose the implementation plan of ecological restoration engineering and recover the shallow sea wetland
ecosystems according to the diagnosis and restoration target.
