摘要:
随着湖泊流域经济的快速发展,蓝藻水华频繁暴发的现象越来越严重,水体富营养化已经成为国内外重大环境问题.浮游植物是水体的初级生产者,是衡量水体富营养化程度的主要指标之一,遥感技术则是探测水体浮游植物时空分布的重要手段.在收集整理近千篇国内外水体浮游植物遥感研究论文的基础上,从卫星数据源、研究内容及研究方法等角度,总结了遥感技术在富营养化湖泊浮游植物监测应用的历史进展、研究重点及发展趋势.研究表明,现有的富营养化水体浮游植物遥感研究,以湖泊蓝藻水华问题为切入点,研究视角由水体表层(藻华面积、色素浓度)转至水下三维(藻总量),研究方法从定性识别转向定量反演,研究内容从监测蓝藻水华推进到探测不同类群蓝藻,逐渐形成了以应用为导向,“MODIS/VIIRS大中型湖泊日常监测-GF/Sentinel2小型湖泊针对性监测-无人机应急监测”的浮游植物遥感综合监测体系.上述研究梳理了富营养化水体浮游植物遥感监测湖泊水环境学科的发展动向,以期为从事蓝藻水华生态灾害监测和预警人员提供重要的技术支撑和理论参考.

Abstract:
With the rapid economic development of lake basins, the frequent occurrence of cyanobacteria blooms has become more and more serious, and the eutrophication of water bodies has become a major environmental problem at home and abroad. Phytoplankton is the primary producer of water bodies and is one of the main indicators to measure the degree of eutrophication of water bodies. Remote sensing technology is an important means to detect the temporal and spatial distribution of phytoplankton in water bodies. Based on the collection and sorting of nearly a thousand research papers on phytoplankton remote sensing in water bodies at home and abroad, from the perspectives of satellite data sources, research content and research methods, the historical progress, research focus and development trends of remote sensing technology in the application of phytoplankton monitoring in eutrophic lakes are summarized. Studies have shown that the existing remote sensing research on phytoplankton in eutrophic water bodies takes the problem of cyanobacteria blooms in lakes as the starting point, and the research perspective is shifted from the surface of the water body (algae bloom area and pigment concentration) to three-dimensional underwater (total algae biomass); The method has shifted from qualitative identification to quantitative inversion; the research content has advanced from monitoring cyanobacteria blooms to detecting different types of cyanobacteria, and gradually formed an application-oriented, "MODIS/VIIRS daily monitoring of large and medium lakes-GF/Sentinel2 targeted monitoring of small lakes" -UAV emergency monitoring" phytoplankton remote sensing integrated monitoring system. The above research combed the development trend of the phytoplankton remote sensing monitoring lake water environment subject of eutrophic water bodies and provided important technical support and theoretical references for personnel engaged in the monitoring and early warning of cyanobacteria bloom ecological disasters.
