中巴卫星数据在海岸带环境监测中的应用

以渤海为示范区,利用中巴资源卫星一号(CBERS-1)CCD数据,结合实测资料,建立了该数据在海岸带及海洋遥感监测中的技术流程,开展了海岸带及海洋环境遥感监测应用示范研究,重点在入海河口污染扩散监测、近岸海洋石油开发活动监测、滩涂养殖污染监测、海域环境监测等方面开展了方法研究和试验。结果表明,中巴资源卫星数据可以在上述应用中发挥重要作用,通过与其它遥感资料和实测数据相结合,可以缩短监测周期,降低应用成本。

The Application of CBERS-1 CCD Imagery in Coastal Environment Monitoring

Taking Bohai Sea as a demonstration area, this paper studies the applications of CBERS|1 imagery in the monitoring of pollutant diffusion, oil development, and coastal environment etc. According to the application demands and the imagery quality, the authors study the image processing methods to enhance the useful information and apply them in the analysis. In the processed image of Laizhou Bay, the river output pollution may be seen clearly. In the Liaohe river mouth, we analyzed the diffusion of into|sea pollutant combining with the field inorganic N data and CCD image. The oil pipes can be seen distinctly in the image, so the CBERS|1 CCD can be used in the oil development and monitoring. The resolution of the CCD image can meet the demand of the aquiculture pollution monitoring. The aquiculture area can be measured from the image, and the COD quantity may be also calculated accordingly. This research shows that the CBERS|1 data has good application prospective in the aspects mentioned above. The monitoring period will be shortened and the cost also be reduced by combining CBERS|1 data with other remotely sensed and in situ data.
