流动空间塑造的沿海国土空间地域功能识别理论

The theory of regional function identification of coastal territorial space under the shaping of the flowing space

信息社会条件下,流动空间加剧时空压缩和区位活化,进而加速经济社会空间重构,地域空间已成为“流动空间”与“场所空间”的复合体,并促使现代地域功能理论更新升级。聚焦区域评价的科学性、要素流动的客观性和陆海统筹的现实性,提出沿海国土空间地域功能识别的理论与模型。(1)基于“因地制宜,唯变所适”的国土空间规划新理念,结合沿海地区海陆要素循环流转的本性特征,构建沿海国土空间地域功能识别的理论框架。沿海国土空间地域功能发展演进的本质是人地(海)关系地域系统的优化调整,不仅要遵循地理空间的适宜性,还应实现地理环境的适应性,只有将静态的区域禀赋与动态的要素流动结合起来,才能实现系统内部人地(海)关系的最优配置。(2)以“空间适宜性”和“环境适应性”为基础,构建国土空间利用的“新空间均衡模型”,将环境适应性作为沿海国土空间地域功能识别的重要补充,重点突出流动要素在区际间、海陆间循环流转、集聚扩散引发的人类活动主动适应过程,提升沿海地域功能识别的流动性特征。(3)针对沿海地区空间规划在分区理论、技术与数据支撑仍面临“海不上陆,陆不下海”的现实困境,以陆海统筹为原则,通过对海陆空间利用矛盾的情景矩阵分析,提炼了陆海统筹的四种模式,探讨行政单元与网格空间海陆要素匹配和空间优化的技术方案。

In an information society,the intensification of flowing space leads to spatial compression and activation,accelerating the restructuring of economic and social spaces.Regional spaces have become a complex amalgamation of "flowing space" and "regional space",prompting the updating and upgrading of modern theories on regional functionality.Drawing upon theories such as the human-sea relationship regional system,location theory,and geographic nature,and focusing on the scientificity of regional evaluation,the objectivity of factor mobility,and the reality of land-sea coordination,this study proposes a theory and model for identifying the regional functionality of coastal land-space.(1) Based on the new concept of "adaptive land use according to local conditions",and considering the inherent characteristics of land-sea element circulation in coastal areas,a theory for identifying the regional functionality of coastal land-space is proposed.The essence of coastal regional development lies in the optimization and adjustment of the human-land relationship regional system.It is necessary to not only adhere to the suitability of geographical space but also achieve adaptability to the geographic environment.Only by combining the static regional endowment with dynamic factor mobility can the optimal allocation of human-land(sea) relationships within the system be achieved.(2) Based on the concepts of "spatial suitability" and "environmental adaptability",a "new spatial equilibrium model" for land-space utilization is constructed,with environmental adaptability serving as an important supplement to the identification of the regional functionality of coastal land-space.The focus is on the active adaptation process of human activities triggered by the circulation,aggregation,and diffusion of mobile factors between regions and between land and sea.This enhances the fluidity characteristics of identifying regional functionality in coastal areas.(3) In view of the practical difficulties faced by the spatial planning of coastal areas in terms of zoning theory,technology and data support,based on the principle of land and sea integration,through the scenario matrix analysis of the contradiction between land and sea space utilization,the four modes of land and sea integration are refined,and the technical scheme of matching land and sea elements and spatial optimization between administrative units and grid space is discussed.
