| 中文摘要: |
| 为明确山东省农田生态系统服务价值的时空变化特征，采用生态经济学评价方法，定量核算了2000—2020年间山东省及省内16个地级市的17项农田生态系统服务价值（包括13个正向服务和4个负向服务）。结果表明：从时间上看，2000—2020年，山东省农田生态系统总服务价值表现出波动增长的态势，农田生态系统提供的服务价值逐渐升高。供给服务和调节服务是最主要的服务功能，合计贡献了83.39%~86.72%，其余支持服务、社会保障服务、文化服务贡献率不足20%。负向服务价值在20年间呈波动递减的趋势。从空间上看，2000—2020年间，环鲁中南山地的平原地区，即潍坊、菏泽、德州、聊城、济宁、临沂6市的农田生态系统总服务价值位居前列，接近全省的2/3。威海、东营、日照、淄博、烟台、滨州、枣庄7市的总服务价值位居末位，不足全省的20%。在单位面积农田生态系统总服务价值上，枣庄、泰安稳居全省前二，此外，枣庄的单位面积农田生态系统负向服务价值常年处于全省第一。建议要在加快农业基础设施建设，改善生态环境的同时，根据不同地区的自然条件合理发展农业生产，采用科学的种植技术和高效的管理方式，提高农业生产效率，持续提升农田生态系统的各类服务价值。 |

| To clarify spatiotemporal changes in the farmland ecosystem service values in Shandong Province，China，an ecological economics evaluation method was used to quantitatively calculate 17 farmland ecosystem service values（including 13 positive services and 4 negative services）provincially and in 16 prefecture-level cities from 2000 to 2020. During this period，the total farmland ecosystem service values in Shandong Province showed a fluctuating growth trend，and the service value provided by farmland ecosystems gradually increased. Supply and regulation services were the most important service functions，contributing a total of 83.39% to 86.72%. Other support services，social security services，and cultural services contributed <20%. The negative service value displayed a decreasing trend of fluctuation. From a spatial perspective，the Weifang，Heze，Dezhou，Liaocheng，Jining，and Linyi plain areas surrounding the central and southern mountainous areas of Shandong ranked among the top in terms of total farmland ecosystem service values，representing nearly twothirds of the province. The total farmland ecosystem service values of Weihai，Dongying，Rizhao，Zibo，Yantai，Binzhou，and Zaozhuang ranked last，representing <20% of the province. In terms of the total farmland ecosystem service values per unit area，Zaozhuang and Tai′an consistently ranked first and second，respectively，in the province. In addition，the negative service value of the farmland ecosystem per unit area in Zaozhuang consistently ranked first in the province. The findings support the view that construction of agricultural infrastructure should be accelerated and the ecological environment improved，while reasonably developing agricultural production according to the natural conditions of different regions，adopting scientific planting techniques and efficient management methods，improving agricultural production efficiency，and continuously enhancing the various farmland ecosystem service values. |
