通常说，全球环境结构是由大气、水圈、地圈和生物圈构成的，它们是自然环境系统。除此之外，我们还增加了另一个系统“生活圈”，这是一个人工系统，但在人类的日常生活和自然系统之间有着密切的关系。在考虑全球环境结构时，自然系统和人工系统是相互联系的，这是适当的。我们建议使用荧光作为一个共同的参数来理解互连。由于各种各样的物质在受到光照射时或多或少地表现出自己独特的自荧光光谱，因此它们是荧光激光雷达的良好目标。激光雷达对在系统之间自由移动的物质的观测结果可能提供有关每种环境系统互连的信息。在这个演讲中，我们展示了几个实验，使用我们开发的荧光激光雷达来观测大气中的气溶胶，水圈中的湖泊/河流水质，生物圈中的植被生长状况，以及在地圈中预观测地表物质和生活圈中生活必需品的废物。我们还描述了一个荧光数据库，它是系统中其他地方发现的物质的EEM（激发-发射矩阵），并讨论了该数据库对荧光激光雷达所做的大气气溶胶观测的适应性。
It is commonly said that the global environment structure is formed from the atmosphere, hydrosphere, geosphere, and biosphere, which are natural environment systems. In addition to this, we add another system “livingsphere” which is an artificial system, but holds strong relations between the daily lives of humans and the natural systems. It would then be appropriate to consider the global environment structure with the idea that natural systems and the artificial one are interconnected. We propose using fluorescence as a common parameter to understand the interconnection. Since a large variety of substances exhibit their own unique auto-fluorescence spectrum more or less if they are irradiated by light, they are good targets for fluorescence lidars. Lidar observation results about substances moving freely among the systems might offer information about the interconnection of each type of environment system. In this presentation, we show several experiments done using the fluorescence lidar we have developed for observing aerosol in the atmosphere, lake/river water quality in the hydrosphere, vegetation growth status in the biosphere, and pre-observing ground surface substances in the geosphere and waste substances of daily necessities in the livingsphere. We also describe a fluorescence database which is an EEM (Excitation-Emission-Matrix) of substances found elsewhere in the systems, and discuss an adaptation of the database to the atmospheric aerosols observation done by the fluorescence lidar.
