Identifying Typical Wetland Vegetation Types Based on Imaging Spectrometer Data: A Case Study in Dongdongting Lake Wetland Area
摘要
Abstract
In order to accurately recognize the vegetation types,spectral information of typical wetland vegetation spectral data was collected by SOC710VP in the core region of the wetland reserve of east Dongting Lake,Hunan province.The first derivative analysis method and the envelope removal method were adopted to analyze the spectral characteristics of the vegetations in the region.By using Fisher linear discriminant function to identify wetland vegetation types,the total classification accuracy reached 88.59%,Kappa coefficient was 0.8247.The recognition accuracy for Carex was the highest (93.55%),followed by Brassica chinensis (92.31%),weeds (86.11%),and the recognition accuracy of Artemisia annua was low (80.65%).The results indicated that the spectral characteristics of the vegetation spectra obtained from the imaging spectral data had good universality and reliability,and it could provide a scientific basis for the identification of wetland vegetation.关键词
