| 摘要: |
| 灌河口自然条件的复杂性及大型整治工程的实施导致该河口海洋水文与海洋环境生态要素发生了一定的时空变化，相关研究时间跨度亦比较大。对1980年以来灌河及其邻近海域的工程环境海洋学和环境生态学领域的研究成果进行了较为系统的整理归纳，并结合2007年的实测水文资料对研究区域内的一些问题进行了探讨。结果表明，在潮差沿程变化、潮流流速的大小潮变化、河口锋面、整治工程导致的泥沙输移、污染物入海量及口外水环境容量、环境生态动力学、沉积物重金属含量和浮游生物的时空变化及其与口外大型整治工程的关系等多个领域尚需进一步研究。 |

| Abstract: |
| Since 1980s, along with the social and economy development in the north of Jiangsu Province, the status of the Guanhe River estuary and its adjacent sea area has became more and more important. A lot of researches on this area have been carried out by the related management departments and scholars. The complex nature conditions and large-scale estuarine regulation works lead to unnegligible temporal and spatial variations of the marine hydrology and marine environment in the Guanhe River estuary. Therefore, many literatures with findings of the engineering environmental oceanography and marine environmental ecology in the Guanhe River estuary from 1980 were summarized systemically, and the hydrologic data measured in 2007 were also adopted for some discussions in this paper. In the general, several problems including spatially variation of tidal range, variation of the spring-neap tide having deferent velocities, variation of the entrance bar, estuarine front, variation of sediment transport induced by the training jetties, assessment of major pollutants inflow volume into the estuarine waters and the marine environment capacity, environmental dynamics and ecological dynamics, the relationships between the temporal and spatial variations of the heavy metal concentrations in the nearshore sediment, the plankton organism and the large-sized regulation works located out of estuary still need to be further studied in the future. Research results show that this study can provide a technical reference for studies and development of the Guanhe River estuary. |
