摘要
城市水体是城市生态系统的重要组成部分,做好城市水体的监测工作是环境监测部门的一项重要任务。遥感作为一种科学、先进的监测手段,能够快速、准确地获取地表的水体信息,成为近年来城市水体监测的主要技术手段。介绍了基于指数法的水体提取方法以及在此基础上进行的变化监测技术,并以重庆市为例,分析了在2010年至2015年间城市水体的变化情况,为相关部门做出正确的决策提供了有效的依据。
Urban water is an important part of urban ecosystem. It is an important task of environmental monitoring department to do urban water monitoring. Remote sensing, as a scientific and advanced monitoring means, can quickly and accurately obtain the surface water information, become the main technical means of urban water monitoring in recent years. This paper introduces the method of water extraction based on exponential method and the change monitoring technology based on it. Taking Chongqing as an example, this paper analyzes the change of urban water body between 2010 and 2015, and makes the correct decision for the relevant departments Provide an effective basis.
