基于Sentinel-2和ZH-1遥感影像的松北区水质监测

Monitoring of Water Quality in Songbei District Based on Sentinel-2 and ZH-1 Remote Sensing Images

水是维持城市生态环境平衡的重要因素,遥感监测手段已经成为评价城市水环境的重要手段。基于2020年4月珠海一号影像和2020年7月哨兵二号影像,建立水质参数反演模型,对哈尔滨市松北区水体的叶绿素a浓度、悬浮物浓度、透明度和综合营养化指数进行季度监测。研究结果表明:松北区银水湾为污染水体,叶绿素a浓度、悬浮物浓度和综合营养指数值都较高,与其相邻的松花江水质情况较好,水质参数均在正常水体值的范围内。

Water is an important factor to maintain the balance of urban ecological environment.Remote sensing monitoring has become an important means to evaluate urban water environment.This study establishs an inversion model of water quality parameters water based on the image of Zhuhai-1 in April 2020 and Sentinel-2 in July 2020,and conducts quarterly monitor the chlorophyll a concentration,suspension concentration,transparency and synthetic trophic index of water quality parameters in Songbei district.The results show that Yinshui Bay in Songbei district is a polluted water body,and has a high chlorophyll a concentration,suspension concentration,transparency and synthetic trophic index.The water quality of adjacent Songhua River is good,and the water quality parameters are all within the normal water body.
