摘要
在全球气候变暖的背景下,湖泊富营养化程度日益加剧导致了全球范围内蓝藻水华暴发频次和暴发范围的逐步增加。利用传统水质监测方法实现蓝藻水华的实时动态监测尚存困难,而遥感技术具有监测范围广、速度快和成本低等优势,于蓝藻水华动态监测中得到了广泛应用。文章在介绍湖泊蓝藻水华遥感监测的原理和方法的基础上,对几种常见卫星传感器在湖泊蓝藻水华监测中的应用现状进行了总结,对比了各种传感器和反演模型的优缺点,最后对目前湖泊蓝藻水华遥感监测研究中存在的不足和发展方向作了分析和展望。
Under the background of global warming, magnitude and frequency of algal blooms in inland lakes have increased globally. Due to time consuming, expensive and not truly representative of traditional water monitoring methods, the use of remote sensing to measure chlorophyll-a from space has been a highly successful technique for mapping algal blooms distribution on a global basis. The principles and methods for remote sensing of algal blooms in inland lakes were introduced, and then a summary of application of common satellite sensors in monitoring algal blooms was made, with the comparison of advantages and disadvantages of various sensors and inversion models. The existing problem and prediction of future research tendency in lake algae monitoring were proposed.
