东海区大陆海岸带高强度开发约束下的陆海统筹水平演化及冲突空间协同优化

陆海统筹作为我国重大国家战略，既要在国家层面实现海陆要素的优化配置，更要在区域层面引导海陆产业的空间布局有利于区域协调发展。以东海区大陆海岸带为案例，分析近40年来海岸带高强度开发的时空特征，构建东海区海岸带陆海统筹度模型，分析东海区陆海统筹水平的区域差异及其时间变化特征，探讨海岸带开发强度约束下的东海区海岸带陆海复合社会经济系统的陆海统筹水平响应机制。基于海岸带土地利用现状与相关空间规划的比较分析，进行海岸带土地利用冲突分类与冲突强度划分。探讨海岸带高强度开发过程对冲突空间特征及演化规律的影响，进而进行海岸带开发利用的空间吻合度及用地演化维度的规划一致性与有效性测度。建立合适的土地利用冲突空间评价单元，从冲突空间评价单元的空间结构现状、空间结构目标及空间质量目标进行功能状态分析及冲突空间的协同优化，为我国陆海统筹战略实施过程中的海岸带地区空间规划制订、实施提供技术手段与科学基础。

As a major national strategy in China, Land-sea coordinate development should not only optimize the allocation of land and sea elements nationwide at the national level, but also guide the spatial distribution of regional land and sea industries at the regional level, which is more conducive to serving regional development. Taking the continental coastal zone of the East China Sea as an example, this proposal tries to discuss the evolution of land-sea coordination level and put forward optimization countermeasures of conflict space in coastal zones under the constraints of high-intensity development of the East China Sea coastal zone: (1) analyze the temporal and spatial characteristics of the high-intensity development of the coastal zone in the past 40 years，constructs a model of the land-sea coordinate development degree of the coastal zone of the East China Sea, analyses the evolution of temporal and spatial characteristics of the land-sea coordinate development level in the East China Sea, and explores the response mechanism of the land-sea coordinate development level of the coastal zone land-sea composite socio-economic system under the constraint of the intensity of coastal zone development. (2) Based on the comparative analysis of land use status and related spatial planning in coastal zone, the classification and intensity division of land use conflicts in coastal zone are carried out. (3) and the impact of high-intensity coastal zone development process on the spatial characteristics and evolution law of conflicts is discussed. Then, the spatial consistency of coastal zone development and utilization and the planning consistency and validity of land use evolution dimension are measured, and appropriate soil is established. (4)Based on the spatial structure status, spatial structure objectives and spatial quality objectives of the conflict space evaluation unit, the function status analysis and the collaborative optimization of the conflict space are carried out by using the conflict space evaluation unit to provide technical means and scientific basis for the formulation and implementation of the coastal zone spatial planning in the process of the implementation of the land-sea coordinate development strategy in China.
