生态系统服务结构是影响生态系统服务协调稳定及人类福祉可持续性的重要因素。在分析汉江流域1990— 2010年生态系统服务价值时空变化的基础上,构建了生态系统服务熵模型,探讨生态系统服务结构特征及其时空演变规律。结果表明:(1)研究区生态系统服务总价值由1990年的3059.764亿元上升到2010年的3466.84亿元,增加了407.076亿元;空间上表现为东南部及汉江干流周围地区生态系统服务价值较高,而东北部及中南部地区相对较低的分布特征。(2)供给、调节、支持、文化四大生态系统服务具有显著的相关性,且空间异质性差异较大。供给-调节、调节-文化、支持-文化之间的相关系数均超过了0.58。供给服务价值高...

Ecosystem service structure is an important factor affecting the coordination and stability of ecosystem service and the sustainability of human wellbeing. In this paper, the spatial and temporal changes in the ecosystem service value (ESV) were analyzed in the Hanjiang River Basin from 1990 to 2010. Then, an ecosystem service entropy model (the ESE model) was established based on information entropy theory, and this model was used to discuss the characteristics of ecosystem service structure and its spatial and temporal evolution law. Our results indicated (1) The total ESV increased from 305...
