摘要:城镇扩张对生态功能的发挥有重要影响。为协调城镇扩张与提升生态效益间的矛盾，本文以湘中丘陵区58个县（市、区）为研究对象，基于2005年和2015年2期土地利用遥感监测数据，借助土地利用转移矩阵、农业生态系统服务价值评估方法、城镇化水平测度、探索性空间数据分析以及构建弹性系数等手段，分析了农业生态系统服务价值和城镇化水平间的时空动态关系。结果表明：1）2005—2015年，农业生态系统服务价值总体呈减少趋势，减少了23.75×108元，高低价值区相互邻近分布；城镇化水平总体呈增加趋势（增加6.24%），大致呈丘陵区中部低四周高的特点。2）城镇化水平和农业生态系统服务价值间具有显著的空间负相关性（P < 0.001），高（低）城镇化水平的区域被低（高）农业生态系统服务价值所包围。3）城镇化水平和农业生态系统服务价值之间主要以冲突关系为主。基于此，未来应强化对绿色植被的保护，合理控制建设用地增长比例，推行产业结构转型，促进资源的集约节约利用，以期协调城镇扩张、农业生产和生态效益间的关系。

Abstract:The intensification of human activities and global climate change has exerted immense pressure on the ecological environment. According to the Millennium Ecosystem Services Assessment, approximately 60% of ecosystem services are declining globally. Therefore, to better maintain ecological health, promote human well-being, and achieve more sustainability in harmonizing environmental protection and socio-economic development, there is an urgent need to explore the relationship between ecosystem service values and urbanization. Using remote sensing monitoring data of land use from 2005 to 2015, this study investigated 58 counties in the hilly region of central Hunan Province. The transfer matrix of land use, evaluation method of ecosystem service values, estimation of the urbanization level, bivariate local spatial autocorrelation analysis, and construction of the elastic coefficient were used to analyze the spatial-temporal relationship between ecosystem service values and urbanization. The results showed that: 1) from 2005 to 2015, the value of agroecosystem services values decreased by ￥ 23.75×108, and the high- and low-value areas were adjacent to each other in the hilly region of central Hunan Province. The level of urbanization increased by 6.24% in general, with low levels in the middle of the hilly area and high levels near the perimeter. 2) There were significant negative spatial correlations between the urbanization level and agroecosystem service values (P < 0.001) from 2005 to 2015. 3) The relationship between urbanization and agroecosystem service values was inconsistent in the hilly region of central Hunan Province from 2005 to 2015. These results provide a reference for coordinating the relationship between urban expansion, agricultural production, and the ecological benefits, strengthening the protection of green vegetation, reasonably controlling the growth of construction land, promoting the adjustment of industrial structure, and exploring the intensive and economic utilization of resources during land space planning.
