以立体化视角重构国土空间利用模式——深圳案例

The reconstruction of land space utilization model from a three-dimensional perspective——Case from Shenzhen

经历一年多的机构改革与政府职能调整,自然资源管理体制逐步得到建立,实现了不同门类空间资源的集中统一管理。新的时代要求充分提升国土空间的利用效率和承载能力。深圳市是典型的高度城市化地区,近年来经历了从增量扩张到存量发展的转变,土地利用模式从二维平面向三维国土空间发展,形成了具有示范性的立体化利用模式。通过对土地利用模式需要转型的认知,本文指出深圳市立体化利用模式的主要构成,针对立体化交通、地下空间开发以及三维地籍技术支持三个方面,构建城市土地立体化利用框架体系,并详细阐述深圳的探索和实践。

With the reform of institutions and the adjustment of government functions in the past two years,the natural resources management system has been gradually established,realizing the centralized and unified management of space resources.In the new era,the utilization efficiency and carrying capacity of land space should be improved.Shenzhen is a typical highly urbanized region.In recent years,it has experienced the transformation from incremental expansion to inventory development,and the land use model has developed from two-dimensional flat to three-dimensional land space,forming a demonstrative three-dimensional land-use model.Based on the recognition of the need of transformation of land use pattern,this paper points out the main composition of the three-dimensional use pattern of Shenzhen,and constructs the framework system from three-dimensional transportation,underground space development and three-dimensional cadastral technical support.And this paper elaborates the exploration and practice in Shenzhen.
