湿地植物生长模型在红树林湿地人工恢复调控中的应用--以珠江口淇澳岛红树林湿地恢复为例

选取珠江口淇澳岛红树林人上恢复为例，借助湿地大型植物生长控制模型，通过3种不同预案的设置，定量分析外来种无瓣海桑与生态侵入种互花米草之间的竞争关系。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问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．无瓣海桑生长基本小受互花米草的影响，同时互花米草的生物量开始下降。在人工付出劳动相同的情况下（即人人工割除互花米草的频度）．初始生物量大的无瓣海桑超过互花米草生物量所需的时间短于初始生物最小的无瓣海桑。

Use of the Growth Models for Wetland Plants in Artificial Rehabilitation and Control of Mangrove Wetland -- A Case study of the Mangrove Wetland in Qi'ao Island Lying Near the Outlet of Pearl River

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.It shows that where Sonneratia apetala is planted in the tidal flat with Spartina alterniflora and its biomass is lower than the biomass of Spartina alterniflora,its plants with a high initial biomass take a shorter time to overtake Spartina alterniflora in biomass than those with a low initial biomass;where its biomass surpasses the biomass of Spartina alterniflora,its growth basically does not suffers from the growth of Spartina alterniflora and that the biomass of Spartina alterniflora begins to decline.Where same human efforts are made(i.e.at the same frequencies to cut Spartina alterniflora),Sonneratia apetala plants with a high initial biomass take a shorter time to overtake Spartina alterniflora in biomass than those with a lower initial biomass.
