Abstract:

The regional and department allocation of land use index is the key problem of National Territory Development Planning System. The most important task in this round of territorial space planning remains the optimal allocation of land use indexes of different types with the full consideration of the development wills of local governments at all levels. The task should be in line with the actual development of China's diverse physical geographic regionalization and economic and social regionalization, in particular, the actual land use in three different regions, namely, urbanization-forming region, urbanization-developing region and urbanization-shrinking region with the implementation of state will and national strategy. In this paper, the authors seek to establish a multi-scale, multi-region and multi-context simulation framework of China's Territorial Spatial Planning Model (CTSPM) based on the Spatial Computable General Equilibrium (SCGE) model, and proposes the actual application contexts in the safety simulation of territorial space for the support of the national territorial spatial framework simulation and analysis of multiple national development contexts and land index allocation planning as well as the analysis of its socio-economic influences and ecological environmental influences. The authors hope that this framework would serve as a "debate" platform for the "game" for obtaining land index between regions and departments and also an analytical framework for a scientific national territorial and spatial planning and a deep understanding of the cross-regional influences of national spatial safety.
