摘要：

针对传统生态系统服务评价方法的主观性强以及评价案例之间可比性差等问题, 建立基于改进的LUCC-ESs矩阵的生态系统服务评估的方法。该方法基于土地利用覆被类型, 建立不同覆被类型的生态系统服务价值量单元, 形成LUCC-ESs评价矩阵, 计算不同覆被类型的生态系统服务, 可以在一定程度上规避由不同核算方法和价值单位引起的结果差异, 使结果具有可比性和实用性。京津冀城市群生态系统服务评价表明, 基础供给服务的供给空间格局具有区域性, 与自然资源的存赋和土地生产力高度相关; 需求服务的空间格局在城市中心区聚集, 向城市周围逐渐递减, 表现出与人口空间格局一致的流动性和聚集性, 京津冀区域内外的基础服务呈现共同向京津冀城市中心区聚集的趋势。

Abstract:

As the traditional ecosystem service evaluation methods have the disadvantageous as high subjectivity and low comparability, a LUCC-ESs matrix evaluation method is improved. Based on the land use/cover types, the proposed method calculates the ecosystem service units, then builds the LUCC-ESs matrix to evaluate the ecosystem services. This method can avoid different outcomes obtained by different calculation methods, and make these test results comparable and practical. The application of the basic supply service in the Beijing-Tianjin-Hebei region indicates that the spatial pattern of the basic supply services is regional and highly connected with resource reserves and land productivities. The spatial pattern of the demand service appears the same movement and aggregation characteristics as that of the population, which decreases from the city center to suburban. The basic services both inside and outside Beijing-Tianjin-Hebei region converge to the urban center. 

Key words: LUCC-ESs matrix, basic supply service, spatial pattern, Beijing-Tianjin-Hebei region
