摘要： 在简单回顾世界城市发展过程中对沿海湿地的威胁和影响上,以广州南沙地区为例,对其城市拓展和生态规划中的湿地综合保护与发展进行了探讨。从南沙地区规划中的功能定位出发,分析了该区的湿地类型和分布特征,对其重点湿地进行了确定,从湿地的功能与价值、湿地资源的稀缺性上分析了湿地保护的重要性,重点对湿地的稀缺性进行了论证。基于相似性理论,特别对十九涌湿地、大虎岛东岸湿地和龙穴岛东岸湿地进行了替代性和补偿性分析,充分论述了建立湿地保护小区的重要性和解决关键联系的必要性。初步对湿地保护小区的功能区进行了划分,提出了湿地优先保护行动。

Abstract: Based on the previous theoretical framework,in this paper we discuss and develop the mode of integrated wetland conservation and development in the context of city expansion and ecological planning by considering Nansha Area in Guangzhou as an example. Using the remote sensing images,wetland distributing maps and the historical data,we divided the wetlands of Nansha Area into three classes,that is,coastal water and seashore wetlands, reservoir wetlands,and irrigation rice wetlands and hydrophyte wetlands.Conforming to the principle of ecological precedence,we select nine ones as the key wetlands from all kinds of wetlands.And then we evaluate and analyze the nine wetlands' conservation values and exploiting pr-ospects from two aspects of the use value and un-use value.The value evaluating results for the key wetlands conservation are in the following order:the 19th Channel>Shiziyang and Zhujiang Estuary Channel> Jiaomen Channel Series>the Eastern Bank of Longxue Island>Hongqili Channel>the Eastern Bank of Dahu Island>Baihuitian and Shenwan Reservoir>the Western Bank of Masha Island> the Western Part of the 15th Channel.Based upen which we testified the rare characteristics of the key wetlands.National,provincial,local,special,and time rarities are the main criteria for valuating the nine key wetlands.In which the 19th Channel and Shiziyang and Zhujiang Estuary Channel represent the highest rare degree.According to the definition for the domestic and overseas nature reserves and the analysis of managing objectives,we define the conservation nature of wetlands in the Nansha Area and identify that the planning direction of wetlands in the Nasha area should be wetland resources and landscape conservation area. Based on the similarity theory,we mainly made a replaceable and compensable feasibility analysis of the 19th Channel,the Eastern Bank of Dahu Island and the Eastern Bank of Longxue Island,the latter two areas are not suitable to replace the first one,but may be suitable to compensate each other to some extent.All the above reasons fully expounded the importance and urgency of building and developing the wetlands conservation area in the Nansha Area.After that,we partition the functional regions of the wetland conservation areas and put forward the action plan of wetland conservation preferentially.
