摘要:城镇化进程伴随着生态用地流失与生态系统服务下降。对生态系统服务与经济发展间一致性的量化与分析，是厘清区域差异、优化空间布局、实现可持续发展的基础。基于青岛都市圈1990-2017年遥感数据与统计年鉴数据，使用当量因子法对生态系统服务价值（Ecosystem Service Value，简称ESV）进行货币化定量核算，进而构建生态系统服务与经济一致性指数，以探讨二者时空协调性特征，并通过驱动因子分析提出区域生态系统服务与经济平衡的优化改善建议。研究表明：受土地利用变化影响，青岛都市圈2017年总ESV较1990年下降11.34亿元。空间上，ESV表现出北东-南西向展布的"高-低-高"分布格局。整体上，青岛都市圈生态系统服务和经济集聚表现出不协调，且不协调范围有所扩大；生态系统服务集聚高于经济集聚主要发生在青岛都市圈西北方向的城市，而经济集聚高于生态系统服务集聚的地区主要分布在东部沿海地带。驱动因子分析表明，ESV减少主要受与城市中心距离的影响。因此，经济集聚高于生态系统服务集聚的地区应管控城镇用地低效蔓延并加强集约利用，同时对具备重要生态功能的要素实施保护；生态系统服务集聚高于经济集聚的地区应积极探索新形势下生态产品转化路径，以实现区域之间的生态与经济协同发展。



Abstract:Urbanization is accompanied by the loss of ecological land and the deterioration of ecosystem services. The quantification and analysis of the consistency between ecosystem services and economic development will provide information to clarify the regional differences, to optimize spatial layout and to achieve sustainable development. Based on the analyses of remote sensing images and statistical yearbook data in Qingdao Metropolitan Region (QDMR) from 1990 to 2017, the Ecosystem Service Value (ESV) was calculated through monetary quantitative accounting using the revised equivalent factor method. The consistent index of ecosystem services and economy was developed to explore their spatio-temporal coordination characteristics. Furthermore, we proposed how to realize a good balance between ecosystem services and economic development through analysis of various driving factors. Our results showed that the total ESV of QDMR in 2017 reduced by 1.134 billion RMB comparing with that in 1990 due to land use changes. Spatially, the distribution of ESV exhibited a "high-low-high" pattern along the northeast-southwest direction. Moreover, the concentration of ecosystem services and economy in QDMR displayed an inconsistency, the area of which had also been expanded. The cities in which the concentration of ecological services was greater than that of economic activities were mainly located in the northwestern part of QDMR, while the opposite situation primarily occurred across the coastal area in the eastern part of QDMR, where the concentration of economic activities was greater than that of ecological services. As indicated by the analysis of driving factors, the decline of ESV was largely attributed to the distance from the city center. Therefore, it is necessary to utilize the built-up land in a more intensive and efficient way, where the concentration of ecological services was greater than that of economic activities. Meantime, the significant ecological elements should strengthen protection. Finally, the new pathway to conversion of ecological products should be explored more vigorously under the new circumstances for the areas where the concentration of ecological services was greater than that of economic activities in order to ensure coordination between ecological and economic development across different regions.
