悬浮物对鱼卵仔稚鱼的影响分析及其损失评估——以厦漳跨海大桥工程为例

Impact of the suspended substance on fish eggs and larvae and losses estimation:Illustrated by the case of cross-ocean bridge engineering from Xiamen to Zhangzhou

以厦漳跨海大桥工程环境影响评价为例,分析工程施工期产生的悬浮物对鱼卵仔鱼的影响。依据2007年5月评价水域渔业资源调查资料,定量估算施工期悬浮物对九龙江口鱼卵仔稚鱼资源的损失量。结果表明,厦漳跨海大桥施工期悬浮物造成鱼卵资源损失量为14.0t;仔稚鱼资源损失量为96.8t。

Taking example for the environmental impact assessment of the Cross-ocean Bridge Engineering from Xiamen to Zhangzhou, the influence on fish eggs and larvae owing to the suspended substance in the construction period was analyzed. According to data from the investigation on fishery resource of Jiulong River Estuary, the losses of the fish eggs and larvae due to the suspended substance were calculated. The results showed that the loss of the fish eggs resources caused by the suspended substance was 14.0t, and the loss of the fish larvae resources was 96.8t.
