    摘要:

    [目的] 对山西省运城市生态系统服务价值(ESV)进行评估,为区域可持续的城市发展模式研究提供科学参考。[方法] 应用中国地级市生态服务价值的研究案例,确立自变量因子,采用Meta分析价值转移法建立运城市景观生态系统服务价值转移模型,并结合2007—2017年期间运城市景观格局估算运城市景观生态价值。[结果] ①研究时间、研究方法、研究区人口与价值转移模型正相关,经济变量与模型负相关;位置变量中,东部和中部地区对生态服务价值有负作用,东北地区则有正作用。②水域景观单位面积生态系统服务价值最大,其后依次是林地、草地、耕地景观。[结论] 运城市生态系统服务价值总体表现出“减少—增加—再减少”变化,且与景观面积变化基本一致,受林地和草地景观影响较大。

    Abstract:

    [Objective] The ecosystem service value (ESV) of Yuncheng City, Shanxi Province was evaluated in order to provide scientific reference for the exploration of sustainable urban development model.[Methods] Based on the case study of ecological service value of prefecture-level cities in China, The independent variables and value transfer model of landscape ecosystem services in Yuncheng City were established based on Meta-analysis method. And the landscape ecosystem service values of Yuncheng City based on its landscape pattern from 2007 to 2017 were evaluated.[Results] ① The research time, research method and the population of the study area were positively correlated with the value transfer model, while the eeconomic variables were negatively correlated with the model. Among the location variables, the eastern and central regions had a negative effect on ecological service values, while the northeastern regions had a positive effect. ② The ecosystem service value of water landscape per unit area was the largest, followed by woodland, meadow and cultivated land landscape.[Conclusion] Ecosystem service values in Yuncheng City shows a change of "decrease-increase-decrease", which is basically consistent with the change of landscape area, and it is greatly affected by the woodland and grassland landscape.
