运用生态系统服务价值变差贡献率分析了1996～2005年兴国县各土地利用变化对生态系统服务价值变化的影响,应用灰色综合关联度探讨了总人口数、城镇化水平、第一产业比重和社会固定资产投资额等指标对生态系统服务价值的贡献测度,并进行了相关性分析.结果表明,1996～2005年兴国县的生态系统服务价值以林地为主,林地面积减小是导致生态系统服务价值持续降低的最主要原因;随着市场需求的进一步增大和当地政府的鼓励政策实施,2001～2005年园地面积快速增加,园地对生态系统服务价值变化的影响程度仅次于林地,居第2位;4项社会经济指标在不同研究期间与生态系统服务价值的关联程度不一样,总人口数、城镇化水平和第一产业比重与生态系统服务价值的关联度较高,但各社会经济指标对生态系统服务价值影响程度日益相当;城镇化水平、固定资产投资额和总人口与生态系统服务价值之间显著负相关,第一产业比重与生态系统服务价值为正相关.

The contribution rate of ecosystem service value variation was used to analyze the effects of land use changes on the changes of ecosystem service value in Xingguo County during 1996-2005.Grey integrated correlation was employed to explore the contribution level of the indicators such as total population, urbanization level, proportion of primary industry and investment of social fixed assets on ecosystem service value, and the correlation analysis was also carried out.The results showed that the ecosystem service value in Xingguo County during 1996-2005 mainly was woodland, and the decrease of woodland area was the major reason for the sustained reduction of ecosystem service value.With the further increase of market demand and the incentives of local government, the garden area rapidly increased during 2001-2005, and the influence degree of garden towards the changes of ecosystem service value was only second to woodland, ranking No.2.Four socio-economic indicators had different correlation degree with ecosystem service value during the different research periods.Total population, urbanization level and proportion of primary industry had high correlation degree with ecosystem service value, whereas the influence degree of various socio-economic indicators on ecosystem service value was equal with each other day by day.Urbanization level, investment of social fixed assets and total population had significant negative correlation with ecosystem service value, while the proportion of primary industry had positive correlation with ecosystem service value.
