摘要

国土空间开发强度（TSDI）与综合承灾能力（CDCC）之间的互动关系对治理体系现代化的成效有着重要影响。研究国土空间开发强度（TSDI）与综合承灾能力（CDCC）之间的内在互动关系具有重要意义。明确地域空间开发强度及其制约因素所诱发的灾害风险，可促进协同发展，应对不确定性。研究从耦合协调的角度探讨了TSDI与CDCC的耦合程度、协调发展水平和动态发展趋势。以京津冀（BTH）地区为例，研究发现：1）京津冀城市群地区的耦合度较高，TSDI 与 CDCC 的相关性较高；2）京津冀地区协调水平濒临失调的城市数量最多，其次是勉强协调的城市；3）在总体协调水平逐渐提高的同时，BTH 城市群地区 TSDI 和 CDCC 发展的总体偏离度逐渐减小；4）BTH 城市群地区的 TSDI 和 CDCC 之间存在交互强制关系。本研究有助于为 BTH 城市群提高城市防灾减灾建设的针对性、调整国土空间结构、促进不同城市协调发展提供决策依据。同时，也为同类地区开展土地适宜性评价、建立国土空间综合防御体系、开展弹性城市规划提供技术支持和理论指导。

Dynamic coupling coordination of territorial spatial development intensity and comprehensive disaster-carrying capability: A case study of Beijing-Tianjin-Hebei urban agglomerations, China

The effectiveness of the modernization of the governance system is significantly impacted by the interaction between the territorial spatial development intensity (TSDI) and the comprehensive disaster-carrying capacity (CDCC). It is of great significance to investigate the intrinsic interaction between the TSDI and the CDCC. Identifying the disaster risks induced by the intensity of the territorial spatial development and their constraints promotes synergistic development to cope with the uncertainty. The study explored the degree of coupling, the level of coordinated development, and the dynamic development trend between TSDI and CDCC from the perspective of coupling coordination. Beijing-Tianjin-Hebei (BTH) Region was used as a case study and it was found 1) there is a higher degree of coupling, and high correlation between TSDI and CDCC in the BTH urban agglomeration region; 2) the BTH region has the highest number of cities with coordination levels on the verge of maladjustment, followed by ones with barely coordinated cities; 3) while the overall level of coordination gradually increases, the overall deviation degree of development of TSDI and CDCC in the BTH urban agglomeration region is gradually decreasing; 4) there is an interactive coercion relationship between TSDI and CDCC in the BTH urban agglomeration region. This study may help provide a decision-making basis for the BTH urban agglomeration on improving the pertinence of urban disaster prevention and mitigation construction, adjusting the spatial structure of the national territory, and promoting the coordinated development of different cities. Moreover, technical support and theoretical guidance for similar regions was also developed to assess the land suitability, establish an integrated defense system of the national territory and space, and exercise resilient city planning.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
