摘要
杭州湾是我国近海岸污染较为严重的区域,传统技术监测污染源面临困难.文章运用遥感技术对杭州湾附近的排污点进行动态监测,快速定位污染源的位置并圈定被污染的水体范围.监测结果发现研究区域内共有13处污染源,其中12处分布在杭州湾南岸,1处分布在杭州湾北岸,水体污染最严重地区为杭州市萧山区,该区域内发现污染源共10处.结合野外实地调查资料,分析污染源的扩散趋势、影响范围和原因,为杭州湾地区的水资源保护和规划提供准确信息.
Hangzhou Bay is a near-shore area with serious pollution in China, there are difficulties to use traditional techniques to monitor pollution sources. This paper used remote sensing technology to conduct dynamic monitoring of Hangzhou Bay, located the pollution sources and calculated the area of sewage quickly and accurately. The results show that there are 13 pollution sources, of which 12 locate in the south bank of Hangzhou Bay, one locate in the north. The most serious water pollution area is Xiaoshan, where 10 pollution sources are found. Combined with the survey data, this paper analyzed the spread trends, influence area and causes of the pollution sources, and provided accurate information for the protection and programming of the water resource in Hangzhou Bay.
