摘要:

在深入阐明生态系统服务与区域生态安全格局之间内在联系的基础上,根据人类社会与生态系统之间以生态服务流为纽带形成的反馈机制,提出基于驱动(Driver)-压力(Pressure)-状态(State)-影响(Impact)-响应(Response)区域生态安全格局研究框架。该框架有助于深入理解区域生态安全维持和区域生态安全问题形成的机制,拓展区域生态安全评估、生态安全格局维持和提升的视野。当前,耦合生态服务的区域生态安全格局研究有3个关键的前沿议题:生态服务需求和生态服务供给的空间耦合及其对人类活动的响应;维持生态系统服务流网络结构完整性和稳定性的人类活动阈值; 耦合人类生态服务供给和需求的区域生态安全评估模型。

关键词: 生态系统服务, 生态系统服务流, 区域生态安全格局, DPSIR框架

Abstract:

Ecosystem services (ESs) are material and spiritual benefits obtained from the composition and functions, and processes occurred in ecosystems. They are fundamental and critical for survival and development of human society. They not only reflect the status of ecological security comprehensively from the aspect of ecosystem by ecosystem services supply, but also provide an avenue for human society to perceive the changes of ecosystem composition and function through changes in ecosystem flows. ES is inherently coupling with regional ecological security. A sustainable supply and delivery of ESs indicates a well regional ecological security. Therefore, ES concept and ES evaluation are essential in assessing regional ecological security status. However, theories and methodology related to integrating ES approach into ecological security assessment are insufficient. It is necessary to give a systematic exploring of methodology for combining ES with regional ecological security pattern. In this study, the inherent connection between ES and regional ecological security pattern is revealed. According to the feedback mechanism between the ecosystem capacity on ecosystem services provision and human societies through ES flow, a Driver-Pressure-State-Impact-Response framework (DPSIR) is outlined. In this framework, ES demand of human society is the driven force; Intensity of ES extraction indicates the pressures; Ecosystem composition and function, and integrality and stability of ES delivery network are defined as state variables; ES supply capacity and capacity to deliver ES to human society are indicators for impact. ES flow is considered as a media to feedback information on ecosystem to human society. This framework is provide a map to study regional ecological security pattern, and may broaden the view of regional ecological security assessment and the regulation of ecosystem pattern for ecological security maintenance and improvement. In the end, some critical research issues that are relevant to the DPSIR framework are given. At present, 3 key issues need to be untangled for the DPSIR framework provided here: 1) response of the spatial coupling between ES demands and ES supply capacity; 2) threshold of human activity intensity for maintaining the integrity and stability of ES flow network; 3) models for regional ecological security pattern assessment and coupling ES demands and ES supply.

Key words: ecosystem services, ecosystem service flow, regional ecological security pattern, DPSIR framework
