| 摘 要： | 孤立湿地是湿地的一种主要类型,具有自身独特的生态功能。受气候变化和人类活动的影响,孤立湿地面积和数量逐渐减少。对于孤立湿地的定义、类型及特征已有一定研究,但孤立湿地功能研究相对较为薄弱,而孤立湿地的功能研究是孤立湿地保护与恢复的前提。基于文献调研,从孤立湿地的水文、生境以及地球化学循环等功能及其功能间的关系综述了孤立湿地功能的研究进展,并分析了孤立湿地功能研究中存在的问题,提出了相应的对策和发展趋势,为湿地恢复、保护与管理提供科学参考。

| Abstract: | Isolated wetland is an important part of the wetlands. Isolated wetland is a kind of main types of wetland with distinctive hydrological, habitat and geochemical cycle functions in itself, which is prominent gradually in the development of human society. Because of climate change and human activity, the area and amount of isolated wetlands increasingly decreases resulting in that its functions are impacted seriously. There has been some research on the definition, type and characteristics of isolated wetlands, but the study to isolated wetland functions is relatively weak, and it is premise to isolated wetland protection and restoration. The research of the definition“isolated wetland”was conducted abroad earlier, but now according to extensive practice and summary, its definition is that the formed wetland is short of relative connection to other water bodies and is isolated in landscape under the joint action of geological factor, climate factor and human interference factor. The types of isolated wetlands in China are called “Annular Wetlands”, “Dish-Like Depression”, “Fragmented Wetlands” and so forth. Therefore, there are a lot of unkown problems in the definitions, types and characteristics of isolated wetlands researches. There are theoretical and practical defects in legislative protection, effective restoration and urban isolated wetlands research at home and abroad. In wetland conservation, most countries have strict legislation to protect the wetland landscape, but they do not regard the isolated wetlands as the objects of protection. In the restoration process, most scholars are lack of the knowledge about restoration techniques leading to that isolated wetlands cannot be effectively protected and restored. The research focus of urban isolated wetlands is different in different countries and regions, and its research methods and system are not perfect lacking of innovation and application. Based on extensive literature research, this paper summarizes the prospect of study on isolated wetland functions from functions of hydrology, habitat and geochemical cycle and so on as well as the relationship among each function, analyzes the problem in study about isolated wetland functions and puts forward that the research on the trend of isolated wetland functions should from focuing on the research and evaluation of the unique functions of isolated wetlands, Strengthening isolated wetland protection and its system construction, improving the recovery theory, technology and construction methods of isolated wetlands and promoting innovation and practical application of research methods on urban isolated wetlands. Especially the constructed or urban wetlands have been the key parts of wetland science researches, from the extensive study, the already known ideas about isolated wetlands functions tend to be applied to more and more important wetland engineering for wetland sustianable development. It can offer scientific reference to wetland restoration, protection and management. |
