Taking the rehabilitation of the mangrove forest in Qi'ao Island lying near the outlet of Pearl River as an example and resorting to the growth models for large-size wetland plants,the paper quantitatively analyzes the competitive relation between Sonneratia apetala,a foreign species,and Spartina alterniflora by prefabricating three different designs.

研究表明：在有互花米草的滩涂上人工种植的无瓣海桑，在其生物量小于互花米草生物量时，初始生物量大的超过互花米草所需时间短于初始生物量小的；当无瓣海桑生物量超过互花米草生物量后，无瓣海桑生长基本不受互花米草的影响，同时互花米草的生物量开始下降。

Tagal was used to treat haemorrhages and malignant ulcers in India. But, C. tagal has not been investigated phytochemically. In continuation of our studies on Chinese mangrove plants, we examined C.

但是，对C.tagal的化学成分少见报道，为了进一步发现红树植物中代谢产物的结构多样性，我们对中国的红树植物——角果木进行了初步化学研究，角果木采自海南岛的红树林。

Tagal collected in the mangrove forest in Hainan Island.Twenty-three compounds were isolated from the petroleum ether portion of the 95% ethanolic extract of the C. tagal.
