遥感技术在上海苏州河水污染监测中的应用

Using Remote Sensing Technology to Monitor Water Pollution of Shanghai Suzhou River

随着航空航天技术的发展,遥感技术越来越多的应用到了城市信息的分析研究,例如在土地利用、城镇布局规划、交通、绿化以及环境监测等方面。遥感技术在环境污染监测方面的应用更加体现了它的优越性,即具有可行、便捷、实效的特点。本文利用遥感信息的空间性、现势性、时相性特征,解译了三张不同时段苏州河的彩色红外遥感影像和热红外遥感影像的信息,分析了苏州河水体污染的状况和历史原因。研究表明:在70年代苏州河水体环境良好,到80年代由于沿河居住人口的急剧增加和工业的过度发展而影响了苏州河的水质,而在90年代,由于人们环保意识的提高以及工厂码头的迁移,苏州河的治理已经取得了明显的成效。

With the development of aeromechanics and aerospace tech no logy,remote sensing technology is more and more used in analytic study of city information,such as land utilization,town planning,traffic,evanescence,and envi ronmental monitoring and other fields.There are many advantages of remote sensi ng technology in environmental monitoring,eg the characteristics of feasibility ,facility and actual effect.In this article,we interpreted the information of three infrared and thermo-infrared remote sensing color photos of Suzhou Rive r taken in three different periods,in the meantime ,we also analyzed the prese nt situation and historical reasons of water pollution in Suzhou River,for m aking use of the characteristics of extensity,the present situation and the t ime phase of remote sensing information.The research indicated that the water condition has been good in70s',but in80s',with the increasing of resident pop ulation and over development of factories along the river,the water condition was severely polluted.Now due to the improvement of people's consciousness of environmental protection and transference of the marinas,obvious effects in h arnessing Suzhou River are achieved.
