珠江口航道疏浚对海洋生态影响及渔业资源损失的定量分析

Quantitative Analysis of Marine Ecological Effects and Fishery Resources Loss due to Waterway Dredging in the Pearl River Estuary

通过对海洋生物资源的现状调查，采用二维水质扩散模型预测，定量分析了航道疏浚、海上倾废对珠江口海洋底栖生物资源和渔业资源的损失及影响．疏浚工程造成主要经济底栖生物资源损失量为１３９７．７ｔ，海上倾废造成邻近海区渔业损失产量为１３３６．４ｔ．

By investigation on marine organism resources, using two dimensional water quality dispersion model, the resource loss and ecological effects on marine benthos and fishery due to waterway dredging and marine sludge discharge have been analyzed quantitatively in the Pearl River Estuary The loss amount of marine benthos resources caused by the dredging project was 1 397 7 t, and the loss amount of fishery production caused by marine sludge discharge was 1 336 4 t.
