| 中文摘要: |
| 南沙湿地类型主要包括河流型湿地、近海岸型湿地、库塘型湿地及其他类型湿地共四大类型。根据实地调查、统计年鉴及历史文献资料，利用市场价值法、影子工程法、替代成本法、收入替代法、费用支出法和成果参照法等评估方法着重对湿地提供的物质生产、污染净化、涵养水源、消浪护岸、提供栖息地、气候调节、休闲娱乐、教育科研等8 种服务功能进行价值评估。结果表明：南沙湿地生态系统服务总价值为61.50 亿元/年，其中环境调节功能价值最大，约为24.76 亿元/年，占湿地总服务价值的40.27%；其次为物质生产功能价值，为21.42 亿元/年，占总价值的34.84%；人文社会服务功能价值为15.31 亿元/年，占总价值的24.90%。从生态系统服务价值比例看出生态系统服务价值的大小与生态系统自身结构功能之间具有直接相关关系。 |
| 英文摘要: |
| The type of Nansha wetland is divided into offshore wetland, river wetland, library pond wetland and other types. According to the survey, statistical yearbook and historical literature, value assessment including material production,pollution purification, water conservation, wave elimination, habitat, climatic regulation, entertainment, education research and so on were assessed by market valuation method, shadow project method, cost replacement method, income replacement method, cost method and results of reference method. The results show that, the value of Nansha wetland ecosystem services is 61.5 billion/year, among which the environment regulation value is the largest, about 24.76 billion/year, account for 40.27% of the total service value；Followed by material production function value with 21.42 billion/ year,accounting for 34.84% of the total value; The value of humanities and social service is 15.31 billion/year, accounting for 24.90% of the total value. From the proportion of ecosystem services value, we can see that the value of ecosystem services is directly related to the structure of ecosystem itself. |
