| 摘 要： | 在文献分析和调查研究的基础上，系统分析了滨海湿地互花米草的生态经济影响，如滩涂淤积、土壤理化性状变化，养殖埕地消失，土著植物退化或基因丧失，底栖生物多样性指数减小，涉禽种群结构数量改变，滩涂经济效益下降；并就互花米草建立了风险评估指标体系；总结指出，应对互花米草的入侵和蔓延采取必要的控制措施．

| Abstract: | On the basis of literature and field surveys, this paper analyzes the ecological and economy impacts of Spartina alterniflora in the coastal wetland, such as intertidal zone siltation, change of physical and chemical properties of soil, loss of mariculture zones, degradation of local plant communities or even genetic loss, decrease of benthic diversity index, change of wading animals and decrease of the economic benefits in the intertidal zone. The authors have developed a risk assessment index system against Spartina alterniflora, and point out in the summary to take necessary measures to control the invasion and spread of Spartina alterniflora. |
