| 如何实现陆海和谐与统筹发展已经成为当前我国生态文明建设中面临的重大问题，沿海城市社会经济发展过程中应当统筹好陆海空间，确保生态安全已经逐渐成为共识。本文从陆海空间生态耦联关系出发，探讨了陆海生态系统连续体和海陆生态交错带的结构与功能，为陆海统筹生态保护修复提供理论基础；分析认为陆海二元结构所导致的生态系统连续体断裂与生态交错带丧失，是亟待解决的难点问题；进一步提出了保护修复生态系统连续体，恢复陆海生态廊道连通，构建多生境生态缓冲空间，并促进陆海空间协同增效的对策建议，为我国推进面向陆海统筹生态保护修复提供基础参考。 |

| Abstract: |
| Achieving the harmony between land and sea and promoting coordinated development has become one of the key issues for the construction of China's ecological civilization. A consensu has gradually been formed that a coastal city should integrate its land and sea space and ensure ecological safety，accompanying with its social and economic development. Here，we discussed the structure and function of land-sea ecosystem continuum and ecotone based on the ecological coupling between land and sea. These two terms originated from ecology and can provide a theoretical basis for integrated land-sea ecological protection and restoration. The rupture of ecosystem continuum and the loss of ecotone，resulted from the dual structure of land and sea management，are ecologically the critical security problems that need to be addressed urgently. Countermeasures and suggestions were put forward，including protection and restoration of the ecosystem continuum and ecological corridor，construction of multi-habitat ecological buffer zone and promotion of the synergy of land and sea. This study can provide a basic reference for promoting the integrated land-sea ecological protection and restoration in China. |
