长江口湿地是我国一块重要的滨海湿地，蕴含了丰富的自然资源，这些自然资源为当地乃至更广领域的经济发展都作出了重要的贡献。本文主要探讨该湿地生态系统中六种具有代表性资源生物的利用现状。这六种资源生物是中华绒螯蟹苗、日本鳗鲡苗、缢蛏、河蚬、芦苇和海三棱草。它们在维持河口生态系统的稳定性和连续性上具有其他许多生物所不可替代的作用。目前由于种种原因，这些资源的持续发展已受到了一定的威胁，造成它们资源现存量下降的主要原因是过度捕捞、受污严重及围垦滩涂等一些因素。如何正确利用和保护这些资源已是一项急待解决的问题，针对这些问题为可持续利用它们提出了一些相应的对策和建议。
The Yangtze River Estuary wetland is an important coastal wetland in China and contains abundant natural resources. These natural resources have made important contributions to the economic development of the local and even broader areas. This article mainly discusses the utilization status of six representative resource organisms in the wetland ecosystem. The six resource organisms are Eriocheir sinensis, Japanese eel seedlings, 缢 蛏, 蚬 蚬, reeds and the sea Triangular grass. They have an irreplaceable role in the maintenance of estuarine ecosystem stability and continuity of many other organisms. At present, due to various reasons, the continuous development of these resources has been threatened. The main reasons contributing to the decline of their existing resources are overfishing, serious pollution and reclamation of tidal flats. How to correctly use and protect these resources has become an urgent problem to be solved, and some corresponding countermeasures and suggestions are put forward for the sustainable utilization of these resources.
