Analysis of the Impact of Green Tide on Aquaculture in Qingdao Based on Remote Sensing

Aquaculture plays an important role in Qingdao Ocean economy. But since 2007 the green tide outbreaks, Qingdao aquaculture losses greatly. The green tide has great intensity, long duration, wide coverage and other unique characteristics which make the risk assessment and disaster loss evaluation of the aquaculture in Qingdao face great challenge. In this paper a method based on graphic grid is put forward to analyze the impact of green tide on Qingdao aquaculture. The actual influence of green tide for years is obtained from the angel of area statistics according to the remote sensing monitoring data since 2008, which implements the green tide rough assessment of the impact of concrete industry.
