摘　　要：黑臭水体对生态环境质量影响严重,加强黑臭水体整治是水环境治理的重要工作。黑臭水体的宏观监测是治理的前提,而遥感技术在宏观监测领域有巨大的优势。目前利用遥感技术识别黑臭水体已有少量研究,本文系统总结了目前黑臭水体遥感识别的研究现状,从反射光谱、水体颜色以及固有光学量3个识别特征分析黑臭水体的光学特性,并分别归纳其识别算法;总结了这些算法可能存在的问题,包括算法通用性问题、大气校正问题导致遥感反射率不准确、对于不同类型水体识别特征出现重叠部分等;最后从进一步挖掘识别特征、进行反射光谱分类、应用机器学习算法3方面对未来的发展趋势进行了展望。The equality of ecological environment has been severely affected by black-odor water bodies,and hence strengthening the treatment of black-odor water bodies is an important task for aquatic environment management.Macro-monitoring of black-odor water bodies is the prerequisite for governance,and remote sensing technology has huge advantages in the field of macro-monitoring.There have been very insufficient studies on black and odorous water bodies.This paper systematically summarizes the current status of identification and recognition of black-odor water bodies,mainly analyzes the optical characteristics of black-odor water bodies from the three identification characteristics of reflection spectrum,watercolor,and inherent optical quantity,summarizes the recognition algorithms and the problems of these algorithms,which include the low versatility of the algorithm,the inaccurate reflectance caused by the problem of atmospheric correction features,and the overlapping features of different types of water recognition features.The future development trends are predicted:①mining recognition characteristics;②performing classification of reflection spectrum;③applying of machine learning algorithms.
