摘要
根据对黄河三角洲的无棣岔尖、东营市五号桩、小清河口的米草分布区与非米草分布区的调查结果,研究了外来物种米草对黄河三角洲地区底栖动物、滩涂昆虫、滩涂浮游动物、滩涂浮游植物、底泥微生物和滩涂鸟类的影响。结果显示,外来物种米草的入侵已导致黄河三角洲地区生态系统结构和功能发生了改变,造成严重的生态失衡和经济损失。
Based on the investigation of rice grass （Spartina anglica） distribution and non -distribution areas in Chajian of Wudi, Wuhaozhuang of Dongying, Xiaoqinghe River Estuary, the effects of exotic species Spartina anglica on the benthic animals, the insects, zooplankton and phytoplankton in tidal fiats, the sedi- ment microorganisms and beach bird of the Yellow River Delta were studied in this paper. The results showed that the invasion of Spartina anglica led to the change of structure and functions of the Yellow River Delta eco- logical system and resulted in great ecological unbalance and economic loss.
