摘　　要：以向海国家自然保护区为例,简要阐述了区内湿地沙化的现状、原因及其对湿地功能的影响。研究表明,人类不合理的开发是造成向海湿地沙化的主要原因。沙化对湿地功能,诸如洪水调控、污染物净化以及提供动植物栖息地等造成了不同程度的破坏。提出了湿地恢复、水资源合理利用等沙化治理和湿地资源可持续开发利用的对策与方案。The present conditions, causes of sedimentation and impacts of sedimentation on the ecological functioning of a wetland in Xianhai town have been studied. Results indicates that human over utilization and poor management are the key causes of the sedimentation of the wetland. The ecological functioning of the wetland, for instance, in flood control, water purification, and habitat provision for waterfowl and other birds, have been seriously affected. Management strategies and measures for wetland restoration and sustainable wetland and water resource use are put forward, with their primary aim being the control of sedimentation.
