Spatial conflicts are formed in the process of urbanization and become the primary drivers of urban ecological and environmental problems. The defining trait of a spatial conflict is the occupation of ecological or agricultural spaces by construction spaces. This work presents a classification scheme for spatial conflicts in China, including source-area conflicts, corridor conflicts, safety conflicts, and farmland conflicts. Also, it constructs a model for the determination of spatial conflicts and conflict intensity using diagrammatic method. Based on a case study performed using our methods on Shenzhen, we proposed a timeline and policy roadmap for the resolution of spatial conflicts in Shenzhen according to the severity and characteristics of spatial conflicts in the city. The results show that the total spatially conflicted area of Shenzhen is 10.57 km, and the percentage of construction land-use in these areas is 1.37%. The spatial conflicts are mainly source-area or corridor conflicts, and minor conflicts account for approximately 60% of the total conflicted area. Most of the spatial conflicts are either "easy to resolve" or "moderately easy to resolve". Overall, in terms of the severity of spatial conflict, Shenzhen remains at the "stable and under control" level. Considering the primary aim of spatial conflict resolution is to revert built-up lands into urban green spaces, we proposed a timeline for the resolution of spatial conflicts in Shenzhen over the next 15 years, as well as a system of supporting policies. The results of this study shall serve as a guide for the optimization of urban spatial structures and the promotion of sustainable urban development.
空间冲突是在城市化进程中形成的，是城市生态和环境问题的主要驱动因素。空间冲突的定义特征是建筑空间对生态或农业空间的侵占。本研究提出了中国空间冲突的分类方案，包括源区冲突、廊道冲突、安全冲突和农田冲突。同时，还构建了一种利用图示法确定空间冲突和冲突强度的模型。基于对深圳进行的案例研究，根据城市空间冲突的严重程度和特征，提出了深圳解决空间冲突的时间表和政策路线图。结果表明，深圳的总空间冲突面积为 10.57km，这些区域的建设用地比例为 1.37%。空间冲突主要是源区或廊道冲突，约占总冲突面积的 60%。大多数空间冲突属于“易于解决”或“中度易于解决”。总的来说，就空间冲突的严重程度而言，深圳仍处于“稳定可控”水平。考虑到解决空间冲突的主要目的是将已建成的土地恢复为城市绿地，我们提出了未来 15 年深圳解决空间冲突的时间表以及一整套支持政策。本研究的结果可为优化城市空间结构和促进可持续城市发展提供指导。
