互花米草 红树林 入侵现状 调查
互花米草 紅樹林 入侵現狀 調查

对福建、广东和广西等省区受到互花米草入侵的有代表性的红树林湿地进行实地调查.调查结果发现:互花米草主要以带状或斑块状分布在红树林的前缘;在红树林内,主要呈斑块状分布于红树林林间空隙处;在红树林密集的地方则难以侵入.互花米草与红树植物存在生态位的重叠,与红树植物竞争阳光和生长空间,容易对周围低矮的红树植物形成遮荫,特别是对红树林幼苗的生长带来不利影响.建议采用本土红树植物科学地营造红树林,以较快形成较高的郁闭度,达到防治互花米草的目的.
對福建、廣東和廣西等省區受到互花米草入侵的有代錶性的紅樹林濕地進行實地調查.調查結果髮現:互花米草主要以帶狀或斑塊狀分佈在紅樹林的前緣;在紅樹林內,主要呈斑塊狀分佈于紅樹林林間空隙處;在紅樹林密集的地方則難以侵入.互花米草與紅樹植物存在生態位的重疊,與紅樹植物競爭暘光和生長空間,容易對週圍低矮的紅樹植物形成遮蔭,特彆是對紅樹林幼苗的生長帶來不利影響.建議採用本土紅樹植物科學地營造紅樹林,以較快形成較高的鬱閉度,達到防治互花米草的目的.

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.
