【摘要】：京津冀城市群健康与可持续发展是保障我国国家安全的重要基础,但因其城市化过程缺乏区域间协同联动,产业布局各自为政,导致生态用地流失、水生态失衡等问题,由此带来生态系统服务下降、生态风险加剧、生态安全受到威胁。因此,如何从区域角度构建科学合理的生态安全格局,成为保障京津冀城市群区域一体化协同发展的关键。在国家重大专项(典型脆弱生态修复与保护研究——京津冀城市群生态安全保障技术研究,项目编号为2016YFC0503000)的支持下,该研究将围绕"区域生态安全保障"这一核心主题,揭示京津冀城市群生态安全格局的维持机制与影响因子,重点研发关键生物栖息地生态修复、受损生态空间生态重建、生态监管与生态风险预测预警技术,进而构建区域协调与空间联动的生态安全保障决策系统和预测预警平台,并开展示范应用研究,为京津冀城市群地区生态安全保障提供技术支撑。
[Abstract]:The healthy and sustainable development of Beijing-Tianjin-Hebei urban agglomeration is an important foundation to guarantee the national security of our country. However, due to the lack of inter-regional coordination in the process of urbanization, the industrial distribution is independent, which leads to the loss of ecological land, the imbalance of water ecology, and so on. As a result, ecosystem services decrease, ecological risk intensifies and ecological security is threatened. Therefore, how to construct a scientific and reasonable ecological security pattern from the regional perspective is the key to ensure the coordinated development of the regional integration of the Beijing-Tianjin-Hebei urban agglomeration. Supported by a major national project (research on typical fragile ecological restoration and protection-research on ecological security guarantee technology for Beijing-Tianjin-Hebei urban agglomeration, the project number is 2016YFC0503000), the study will focus on the core theme of "regional ecological security guarantee". It reveals the maintenance mechanism and influencing factors of ecological security pattern in Beijing-Tianjin-Hebei urban agglomeration, and focuses on the research and development of ecological restoration of key biological habitats, ecological reconstruction of damaged ecological space, ecological supervision and ecological risk prediction and early warning technology. Furthermore, the decision-making system of ecological security guarantee and prediction and early warning platform of regional coordination and spatial linkage are constructed, and demonstration application research is carried out to provide technical support for ecological security guarantee of Beijing-Tianjin-Hebei urban agglomeration.
