摘要
本文通过介绍河口三角洲湿地生态参数(水体/泥滩/植被)的光谱特征,对比了不同特征植被的光谱曲线差异,探讨了最新的湿地遥感影像的信息提取技术及研究成果,综述了湿地景观生态指标参数的计算和基于景观指标的湿地生态健康评价。高分辨率遥感卫星技术的使用,将使人们在湿地研究中把宏观尺度,中观和微观尺度高度地统一,更加全面的把握湿地生态系统内部的变化趋势。
In this paper,the ecological parameters and spectral characteristics in the delta wetland（water body / mudflat / vegetation） were introduced.the comparing the differences of the spectral curve of different vegetation,probing into the latest information extraction technology of wetland remote sensing image and research results,the summarization of the wetland landscape ecological parameters calculation and the wetland ecosystem health assessment was made based on landscape indicators.With the development of the High-resolution remote sensing satellite technology,in the wetland research,macro-scale,meso-scale and micro-scale research areas can been highly united.
