桑沟湾养殖水域的初级生产力及其影响因素的研究

PRIMARY PRODUCTIVITY AND THE AFFECTING FACTORS IN SANGGOU BAY

桑沟湾是我国黄海沿岸的重要水产养殖水域。近年来，由于该养殖水域的养殖密度大幅度增长，引发了养殖生物低增长率、高死亡率和养殖生产上高投入、低产出等问题的产生。通过本次调查，作者初步了解了该海域初级生产力分布状况及其季节变化以及水产养殖状况和其他环境因素对初级生产力的影响，并与１０年前的历史调查资料相比较。

China's Sanggou Bay is an important water body for aquaculture. In the past ten years,the cultured species have suffered lower growth rate and higher death rate resulted from increasing culture density in its waters. The horizontal distribution and seasonal change of primary productivity and the effect of aquaculture and other environmental factors on primary productivity are discussed and compared with data obtained ten years ago.
