| 摘 要： | 本文尝试通过分析滩涂上外来入侵植物群落的植物学和生态学特征,就闽东宁德地区三都湾海域的互花米草生长与变化状况,探讨如何实现利用遥感数据快速监测滩涂上的外来入侵植物的方法,为生物入侵监控工作提供决策依据.研究表明以缨帽变换的方法处理LandsatETM 和TM多光谱数据所获得的土壤视面和植被视面为基础,进行分层次分类可监测滩涂上互花米草的生长与分布扩展状况.

| Abstract: | Taking the growth and expansion of smooth cordgrass(Spartina alterniflora) in the Sandu Bay as a case, this paper explores the application of remote sensing data for instant monitoring of intertidal zone plant invasion on the basis of botanical and ecological features of the invaded plant communities. The layered classification of Landsat ETM and TM multispectral images of intertidal zone soil and vegetation with tasseled cap trasform is adopted in the image processing. The results show clearly and truly the distribution and expansion trend of smooth cordgrass and prove that the remote sensing approach is useful for monitoring plant invasion in the intertidal zone. |
