Abstract: |
This paper investigates and studies the resource and current situation of mangrove ecosystem in
Guangdong coastal area. With the phenomenon of reclamation, aquaculture, land occupation by urban construction,
discharge of urban and industrial sewage in recent years, the mangroves ecological environment was badly destroyed
and the mangroves acreage have been greatly reduced. Currently, the existing mangrove communities are facing
problems of serious invasion of exotic pests such as Spartina alterniflora, deterioration of stand quality and system
function, lack of genetic diversity, high level technical requirements on coastal mangrove afforestation and high
cost on construction. According to the conditions of coastal beach in Guangdong province, as well as mangrove
management and protection characteristics, this paper proposes corresponding mangrove ecological protection and
restoration models and key technologies of special site restoration and construction in order to provide theoretical
basis and technical guidance for the protection, restoration and construction of coastal mangrove ecosystem. |
