摘要
湿地由于具有丰富的资源、独特的生态结构和功能而享有"自然之肾"之称。生态系统脆弱性研究是当前环境科学和生态学研究的热点问题之一,湿地生态系统脆弱性评价是湿地评价研究的新概念和新领域。在对生态脆弱性的相关概念进行讨论的基础上,对国内外湿地生态脆弱性研究进行了回顾。近年来,国内外湿地生态脆弱性评估发展很快,取得了丰硕的成果,但也存在一些问题和不足,如缺乏长时间序列数据支持;对湿地脆弱性的复杂程度认识不足;技术手段创新少等。因此,今后湿地脆弱性研究应该将重点放在理论探索和方法完善方面,对应用研究加强引导和规范,增强湿地脆弱性评估的科学性和说服力,为湿地的科学保护和管理提供有力的支持。
Wetland is known as ＂Kidney of Nature＂ for its rich resources,unique ecological structure and function.The study on the vulnerability of ecosystem is one of the hot issues of the current environmental science and ecology study.The assessment of wetland ecological vulnerability is a new conception and a new domain of wetland assessment research.Based on the discussion of related conceptions of ecological vulnerability,the present study reviews the study of wetland ecological vulnerability at home and abroad.The assessment of wetland ecological vulnerability at home and abroad has developed very fast and made considerable achievements in recent years.Nevertheless,there are also some problems and deficiencies including lacking the support of long-time series data,insufficient understanding of the complexity of wetland,little innovation in technological means,etc.So hereafter,the study of wetland vulnerability should place emphasis on theoretical exploration and the perfection of method,reinforce the guidance and standardization of applied research,enhance the scientificalness and persuasion of the assessment of wetland vulnerability,and provide strong support for the scientific protection and management of wetland.
