| 填海空间作为连接陆地与海洋的重要部分，是陆海统筹发展的关键一环。文章以深圳为例，通过整理 1980—2020 年深圳市域的Landsat遥感影像，对填海规模及海岸线变化进行分析，结合发展背景将深圳填海历程分为4个阶段：试点发展下的临港企业自主建设（1980—1986年）、政企分离中的地方产业基建铺开（1986—1996年）、资源短缺下的政府双重角色强化（1996—2010年）和存量优化中的填海多元利益考量（2010—2020年）。最终填海总面积达91.68 km2，自然岸线保有率下降49.92%，且持续多年的填海对海岸带生态安全状况造成了负面影响。基于此，文章指出政府作为利益导向政策主体对其自身及企业和公众关于填海的行为观念产生了重要影响，最终推动了填海发展符合城市社会整体利益。最后，以深圳填海空间演变过程为鉴，其他沿海城市的空间发展应关注历史填海项目的生态修复与利益补偿和新增填海项目的经济与生态利益权衡。 |

| Abstract: |
| Reclamation space, as an important part connecting land and sea, is a key link in land-sea coordination. Taking Shenzhen as an example, by combing the Landsat remote sensing image data from 1980 to 2020, analyzing the scale of reclamation and the change of coastline and interpreting the background, it is found that the reclamation history in Shenzhen has gone through four stages: independent construction by harbor enterprises under pilot development (1980—1986), expansion of local industrial infrastructure in the separation of government and enterprise (1986—1996), strengthening of the dual role of the government under resource shortage (1996—2010), and consideration of multiple benefits in optimization of stock space (2010—2020). The total reclamation area reaches 91.68 km2，the retention rate of natural coastline has decreased by 49.92%, and the continuous years of reclamation have had a negative impact on the ecological security of the coastal zone. On this basis, this paper points out that the government, as the benefit-oriented policy subject, has had an important impact on its own, corporate and public behavior on reclamation. Finally, based on the experience gained from Shenzhen, the spatial development of other coastal cities should focus on the ecological restoration and benefit compensation of historical reclamation projects and on the trade-off between economic and ecological benefits of new reclamation projects. |
