黄海陆架锋特征及其生态效应的初步分析

A Preliminary Analysis of the Characteristics of the Continental Shelf Front and Its Ecological Effects in the Yellow Sea

黄海陆架锋是影响中国东部陆架边缘海生态系统的一种关键的中尺度物理过程,对局部的生物地球化学过程非常重要。不少学者也致力于黄海陆架锋的研究,通过分析观测资料和数值模拟,不断认识和揭示了陆架锋的产生机制及其分布和变化规律,同时,在锋区环流结构以及陆架锋与一些生态学现象的联系方面也取得了一定的进展。在系统总结和归纳黄海陆架锋相关研究成果的基础上,阐述了陆架锋的生态效应和生态功能,并对今后黄海陆架锋区研究的着力点进行了分析,提出通过开展锋区生态系以及锋区生态系统动力学等方面的研究,有希望成为海洋生态学中新的生长点,同时也为黄海海洋生态学的研究提供新课题。

The existence of the continental shelf front in the Yellow Sea is a critical mesoscale-physical process which can influence the ecosystem of the eastern marginal sea of China,and it is also very important to the local bio-geochemical processes.Many scholars have committed to the research of the continental shelf front in the Yellow Sea.By analyzing observational data and numerical simulation,the forming mechanism of the continental shelf front as well as its distribution and variation have been revealed continuously.Meanwhile,some progress has also been made in the research of the circulation structure in the front zone as well as the relationship of the continental shelf front and some ecological phenomena.Based on the introduction and summary of the research progress of the continental shelf front in the Yellow Sea,this paper expounds the ecological functions and ecological effects of the continental shelf front.Besides,the development direction and focus of research on the continental shelf front are analyzed.It is pointed out that carrying out the research on the front region ecosystem and the front region ecosystem dynamics can not only become the new growth of the marine ecology,but also provide a new research project for the marine ecology of the Yellow Sea.
