| 摘 要： | 基于1975、2006年若尔盖高原湿地的卫星遥感资料，应用生态系统服务价值评价方法，对1975—2006年间若尔盖高原湿地生态系统的物质产品生产价值、气体调节价值和蓄水价值动态进行了研究.结果表明：研究期间，若尔盖高原湿地生态系统三项服务价值总和由195.90亿元降至123.85亿元，其中，物质产品价值增加了3.02亿元，而气体调节和蓄水价值共减少了75.07亿元.研究区由物质产品增加带来的收益远小于由生态退化造成的损失；过度的放牧行为致使若尔盖高原湿地生物量减少、土壤结构变化，造成生态系统总服务价值和服务水平下降. |

| Abstract: | Based on the satellite remote sensing data acquired in 1975 and 2006, and by using the assessment method of ecosystem service value, the dynamic changes of physical production value, gas regulation value, and water storage value of Ruoergai Plateau wetland ecosystem in 1975〖KG-*2〗-〖KG-*7〗2006 were studied. During study period, the total value of the three services decreased from 1959 billion RMB Yuan to 1238 billion Yuan RMB, among which, physical production value increased by 0302 billion RMB Yuan, while the gas regulation and water storage value decreased by 7507 billion RMB Yuan. The benefit from the increase of physical production was much less than the loss of ecosystem degradation. Overgrazing induced the biomass reduction and soil deterioration, resulting in the decline of Ruoergai Plateau wetland ecosystem service value and service capacity. |
