珠江口渔业资源用地适宜性评价

Land Suitability Evaluation of Fishery Resources in the Pearl River Mouth

采用海水水质和海底沉积物质量两个因子,对珠江口的渔业资源用地适宜性作出评价。结果表明,近岸的适宜性普遍较差,特别是河流入海口。较好的区域主要分布在距离岸边较远的水域,这些地方水域开阔,海水流动性较好,受到来自大陆的污染较少。

Land suitability of fishery resources in the Pearl River mouth was evaluated using factors of water quality and sediment quality.The results showed that,the suitability is generally poor near the shore,especially the river estuaries.Good suitability areas mainly distribute far away from the mainland,where the sea water is open with good fluidity and receives less pollution from the mainland.
