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。
Using the contribution of deteriorating values of ecosystem services, this paper analyzes the impacts of land use change on ecosystem service value changes in Xingguo County from 1996 to 2005. The total population, urbanization level, the proportion of primary industry, Social investment in fixed assets and other indicators of the value of ecosystem services to measure the contribution and conduct a correlation analysis. The results showed that the value of ecosystem services in Xingguo County was dominated by forest land from 1996 to 2005, and the decrease of forest land area was the most important reason that the value of ecosystem services continued to decrease. With the further increase of market demand and the encouragement of local governments , The area of the garden increased rapidly from 2001 to 2005. The degree of influence of the park on the ecosystem service value was second only to the forest land, ranking the second place. The four socio-economic indicators were not related to the ecosystem service value in different periods, The total population, the level of urbanization and the proportion of the primary industry are highly correlated with the value of ecosystem services, but the socio-economic indicators have a more or less equal impact on the value of ecosystem services. The level of urbanization, the investment in fixed assets and the total population and There is a significant negative correlation between ecosystem service value and the proportion of primary industry and ecosystem service value.
