【摘要】 指出了北大港湿地为人类和生态系统提供了重要的产品和服务功能,但由于人类对其价值认识不足,给湿地的可持续发展造成了一定的影响。结合北大港湿地生态系统的结构和功能,将北大港湿地的价值分为了大气调节价值、气候调节价值、蓄水调节价值等10类,核算了北大港湿地的总价值。计算结果表明:北大港湿地的价值为26.6亿元,其中生态价值占比52.2%。北大港湿地的主导功能为生物多样性保育功能、文化教育功能和生物产品供给功能。水资源匮乏和人类扰动均可能造成北大港湿地生态价值损失,因此开展北大港湿地的可持续发展研究意义重大。更多还原

【Abstract】 Beidagang wetland provides important products and service function for human being and eco-system.However,its value is always underestimated,which hold back its sustainable development.In consideration of the structure and function of the eco-system,the total value of the wetland is divided into 10 categories including atmospheric regulating value,climate regulation value,water regulating value,etc.,and the value of Beidagang wetland is evaluated.Results show that the total value of the Beidagang wetland is 2.66 billion RMB,in which 52.2%value belongs to ecological value.The dominant functions of the wetland are biodiversity conservation function,cultural and educational function and biological products supply function.The scarcity of the water resource and the disturbance of human beings could cause huge value losses to Beidagang wetland.Therefore,it is of great importance to investigation of the sustainable development of the wetland.更多还原
