摘要:

根据千年生态系统评估提出的评估概念框架,考察鄱阳湖湖区生态系统服务功能的形成机理,构建了鄱阳湖湖区生态系统服务功能表征指标体系,并利用多主题1km栅格成分数据模型,采用主成分分析法提取了鄱阳湖湖区核心生态系统服务功能综合表征指标。在此基础上,通过空间聚类分析,形成了鄱阳湖湖区生态系统服务功能分区,实现了各分区单元上生态系统服务功能的空间辨识。研究结果表明,鄱阳湖湖区核心生态系统服务功能包括了支持功能、供给功能、调节功能和文化功能,它们在空间上的排列组合形成了鄱阳湖湖区的10个生态系统服务功能分区,本文辨识了鄱阳湖湖区精细栅格水平上核心生态系统服务功能之间的差异及其空间分异特征。本研究提出的生态系统服务功能分区及其空间辨识方案,为鄱阳湖湖区生态系统服务功能的开发与保育提供决策参考信息。

Abstract:

Based on the assessment framework of Millennium Ecosystem Assessment (MA), considering the shaping forming mechanism of ecosystem services in Poyang Lake area, we constructed the evaluation index system for ecosystem services in Poyang Lake area. By using the 1km grid percentage data model, we carried out the principal component analysis to extract the principal factors characterizing the core ecosystem services of the Poyang Lake area. On this basis, the spatial clustering analysis was done to identify and delimitate the zoning boundary of ecosystem services in the Poyang Lake area and the ecosystem services of each district was spatially identified. The research results show that the core ecosystem services in the Poyang Lake area include supporting function, provisioning function, regulating function and cultural function in 1km by 1 km grid pixels. And then ten functional zones of ecosystem services are generated, and the spatial heterogeneity of the core ecosystem services on different administrative divisions in the Poyang Lake area was identified and presented. The application of the spatial zoning scheme of the core ecosystem and its spatial identification can provide both spatially and temporally valuable information for ecosystem management in the Poyang Lake area.
