摘要: 对湖南省生态服务价值和不同层级交通可达性进行测算,以区(县)为基本单元,使用地理加权回归模型,揭示了与不同层级城市联系的交通可达性对生态服务价值的影响。研究发现,县级城市交通可达性对生态服务价值的负面影响由长沙-株洲-湘潭城市群向外围逐渐减弱,并在湘西南地区转变为正面影响。地级城市交通可达性对生态服务价值的影响机制与县级城市类似,且负面影响的范围有沿铁路向西北蔓延的趋势。大型城市交通可达性对整个湖南省的生态服务价值都具有正面影响,以东部最强。在考虑不同地区不同层级交通可达性对生态服务价值影响存在差异的基础上,采取适合当地的交通基础设施建设方案以及产业结构转型升级策略,在促进社会经济发展的同时维护和提升区域生态服务价值。

Abstract: : The spatial characteristics of the ecosystem service value and accessibility to cities on three different levels(county-level cities,prefecture-level cities and mega cities) in Hunan Province are analysed. And three geographically weighted regression models are built to help revealing the impact of traffic accessibility on ecosystem service value. The results indicate that the negative impact of the accessibility of urban transport on the ecological service value from the urban agglomeration of Changsha-Zhuzhou-Xiangtan to the periphery is weakened and turned into a positive influence in the southwest of Hunan Province. The influence mechanism of the accessibility of the urban traffic on the ecological service value is similar to that of the county-level city,and the negative influence extends to the northwest along the railway. The accessibility to large cities has a positive impact on the ecological service value in whole Hunan Province,with the strongest in the east. Transport infrastructure construction and economic upgrading strategies should take the differences in the impacts of different levels of traffic accessibility on ecosystem services value in different regions into account to promote social and economic development while maintaining and developing the local ecological service value.

Key words: traffic accessibility, ecological service value, multiple administrative levels, geographically weighted regression
