Investigation on the Invasion Status of Spartina alterniflora to Mangrove Wetlands
Some representative mangrove wetlands invaded by Spartina alterniflora in Fujian province,Guangdong province and Guangxi Zhuang Autonomous Region were surveyed.The result showed that Spartina alterniflora mainly grew at the front edge of mangrove,showing zonal or patchy distribution;some grew in mangrove forest gaps as patchy distribution,and it could hardly invade into the dense mangrove forest.The niches of Spartina alterniflora and mangrove plants are overlapped,they compete for sunshine and growth space,and the rapid growth of Spartina alterniflora can easily shade to low mangrove plants around them,especially have adverse effects on the growth of mangrove seedlings. Afforestation using native mangrove species and scientific planting methods are recommended,to make the native mangrove plants rapidly form high canopy density,achieving the goal of control to Spartina alterniflora.
