摘要: 应用生态经济系统能值分析理论,定量分析广州市南沙地区十九涌红树林沼泽湿地的生态效益以及系统内的物流和能流.结果表明,2002年红树林的能值-货币价值为1.88×104美元,湿地水禽和水产的能值-货币价值分别有22.78×104美元和12.00×104美元,湿地系统能值总投入17.96×1016sej,不可再生能源9.44×1016sej;产出能值总量31.28×1016sej.通过湿地生态系统能值分析图和能值分析表,可以看出南沙十九涌红树林沼泽湿地整体投入/产出的效益非常合理,即投入少(10.49×104美元),产出量大(42.82×104美元),说明红树林湿地具有低投入高产出的特点.

Abstract: The energy and material flux in addition to ecological benefits in the Nineteenth Chong mangrove wetland in Nansha of Panyu district,Guangzhou City were analyzed quantificationally with the energy analysis method of ecological economy system.The results showed that nummary value of the mangrove was $ 1.88?104 in 2002,$ 22.78?104 and $ 12.00?104 for waterfowl and aquatic product,respectively.The total eergy input of wetland system was 17.96?1016sej,unrenewable 9.44?1016sej,while the total output was 31.28?1016sej.The energy analytical figures and tables indicated that the integrated rate of input/output of the mangrove wetland is reasonable with low input ($ 10.49?104) but high output ($ 42.82?104).Related suggestions were put forward.
