“天地一体化”水环境监测系统

Integrated Space-Ground Monitoring System for Water Environment

介绍了“天地一体化”水环境监测系统的概念与结构特点，罗列了构建天基监测系统和地基监测系统的重难点，最后阐述天基与地基联合监测的必要性与重要意义。近年来我国内陆湖泊水质遥感反演模型的精准度误差均在20％以上，除大气校正，且需在现有基础上对天基和地基系统改良，提升水环境监测系统的高效、实时和精准的空间覆盖率，增加遥感反演模型精度。未来该监测系统的实时性、大尺度、高速度、动态性等优势，将有利于实现“十三五规划”目标，即建立全国统一的实时在线环境监控系统。

Firstly, this paper introduces the concepts and structure of the Integrated Space-ground Monitoring System of water environment （ISMSE）, then lists the difficulties for ISMSE construction, finally elaborates the necessity and important significance for united space and ground monitoring system.The remote sensing retrieval model errors of inland lakes in our country were more than 20% in recent years. In addition to atmospheric correction to improve the accuracy of retrieval model, there is a necessary for improvement on the basic system in space and ground which improves the efficient, real-time and accurate spatial coverage of model. The advantages of ISMSE in large scale, high speed and dynamics are conducive to the realization of the ＂13th Five-Year plan＂ which is to establish a unified national real-time online environmental monitoring system.
