基于遥感的城市水环境监测方法研究

Study on Urban Water Environment Monitoring Methods Based on Remote Sensing

随着科技的进步,传统的环境监测手段因其技术滞后、监测成本高、效率慢,覆盖面窄,逐渐被卫星遥感技术所替代。对城市的生态环境监测也开始采用卫星遥感技术,在环境保护领域着重分析城市主要水体的遥感监测,研究分析了遥感技术应用在水体监测的原理与方法、卫星数据的提取,并通过实地采样的数据与遥感提取的灰度值进行关联性的回归分析,生成数学关系,用作卫星遥感水体环境的反演,以达到实时环境监测的目的。

With the progress of science and technology,the traditional means of environmental monitoring are gradually replaced by satellite remote sensing technology because of its disadvantages such as obsolete technology,high monitoring cost,low efficiency,and narrow coverage.Satellite remote sensing technology is gradually used in the monitoring of urban ecological environment.In the field of environmental protection,it focuses on the remote sensing monitoring of the main water bodies in the city.The principles and methods of the application of remote sensing technology on water body monitoring are studied and analyzed,including the extraction of satellite data,and the regression analysis of correlation with the grayscale values extracted by the field sample data.The mathematical relationship is generated and used as an inversion of the satellite remote sensing water environment in order to achieve real-time environmental monitoring.
