【摘要】：滨海湿地是介于海陆之间的过渡地带,具有丰富的生物多样性和很高的生产力,能为人类提供诸多生态系统服务,但它又是对人类活动极为敏感的生态脆弱区。沿海经济的发展使湿地资源的有限性与人类需求的无限性之间的矛盾日益突出,导致湿地多样性丧失、服务功能退化等。在阐述滨海湿地特征及其服务产生机理的基础上,介绍了运用经济学方法对生态系统服务进行评价的进展,分析了各方法的优缺点及应用情况,最后对滨海湿地生态系统服务价值评估中存在的问题进行了总结归纳,评估所面临的困难一方面来自生态系统本身的复杂性;另一方面来自经济学方法的局限性。因此今后的研究应从生态系统服务的形成机制入手,注重生态学及经济学理论的结合,改善评估方法,提高评估结果的有效性和可信度,为湿地资源管理及生态补偿机制制定提供有力支持。
[Abstract]:Coastal wetland is a transitional zone between sea and land. It has rich biodiversity and high productivity, which can provide many ecosystem services for human beings, but it is also a fragile ecological region sensitive to human activities. With the development of coastal economy, the contradiction between the limitation of wetland resources and the infinity of human needs has become increasingly prominent, resulting in the loss of wetland diversity and the degradation of service functions. On the basis of expounding the characteristics of coastal wetland and its service generation mechanism, this paper introduces the progress in the evaluation of ecosystem services by using economic methods, and analyzes the advantages and disadvantages of each method and its application. Finally, the problems existing in the evaluation of ecosystem service value of coastal wetland are summarized. The difficulties encountered in the assessment come from the complexity of the ecosystem itself and the limitations of the economic methods on the other hand. Therefore, the future research should start with the formation mechanism of ecosystem services, pay attention to the combination of ecology and economic theory, improve the evaluation methods, and enhance the effectiveness and credibility of the evaluation results. To provide support for wetland resource management and ecological compensation mechanism.
