Effects of Using Sonneratia apetala to Control the Growth of Spartina alterniflora Loisel

TANG Guo-ling~1,SHEN Lu-heng~1,WENG Wei-hua~1,ZHANG Jia-en~1,LIAO Bao-wen~2,LIU Jin-ling~1,TENG Xing-shun~1 (1 College of Agriculture,South China Agric.Univ.,Guangzhou 510642,China;2 Institute of Tropical Forestry,Chinese Academy of Forestry Science, Guangzhou 510520,China)  
Field investigation on effects of planting Sonneratia apetala to control the growth of Spartina alterniflora Loisel was conducted at the wetlands in Qi'ao island,Zhuhai,Guangdong.The results showed that,with year addition of planting Sonneratia apetala, the growth was affected,the height,coverage,richness,frequency and biomass of Spartina alterniflora decreased.while the mass ratio of stem to leaf and the ratio of wet to dry mass increased.This indicated that planting Sonneratia apetala can effectively control the rapid growth of Spartina alterniflora and also restore the mangrove wetland ecosystem.
