土地利用变化是对生态系统服务产生胁迫的主要驱动力之一.论文以厦门岛为例,分析生态系统服务对土地利用变化的响应,基于对2007年中国陆地生态系统服务价值当量修正的两种方法,对厦门岛生态系统服务价值(ESV)变化作出评估.研究表明:1950～2007年间,两种方法得出的厦门岛ESV变化趋势一致,随岛内土地利用强度逐年增加均呈减少态势,1987年前厦门岛ESV因水域和湿地增加12.87 km~2,而提高了1 076 655元;1984年厦门岛设立经济特区后快速城市化导致ESV急剧降低,1987年后年均损失达619 773元.随着厦门岛内各土地类型利用趋于饱和,及2006年厦门环东海域综合整治工程等生态措施的实施,预计未来ESV降低的趋势将得以缓解.从生态系统服务价值全面修正的方法解决了仅从供给服务方面修正造成结果偏高的问题.

Land use change is a major factor affecting ecosystem services. Taking Xiamen Island as an example, the authors examine the land use patterns from 1950 to 2007 by integrating remote sensing data and evaluate the regional ecosystem services based on two revised methods so as to identify the effects and mechanisms of land use change on ecosystem services. The results showed that during 1950-2007 land use intensity of Xiamen Island had been annually rising generally. The changing trends of ecosystem service value of Xiamen Island obtained by two methods were consistent, which were decreased with the decreasing of land use intensity. Before 1987, ecosystem service value of Xiamen Island had increased by about 1.07 million yuan due to the expanding of 12.87 km~2 water and wetland areas. Since the establishment of Xiamen Special Economic Zone in 1984, rapid urbanization has resulted in a sharp decline in ecosystem service value, and average annual loss reached to 619 773 yuan after 1987. With the utilization of land reaching saturation and launching of ecological projects, such as the Xiamen Eastern Sea Comprehensive Improvement Project, it can be predicted that decreasing trend of ecosystem service value is going to slow down in the near future. The problem of overestimating service value by correction made from a single aspect can be solved by applying ESV total correction method.
