Progress and Prospects of Research on Optimal Land-Use Allocation Modeling

The optimal allocation of land-use is an important technical means to solve the contradiction between supply and demand of land resources and to coordinate social and economic development with ecolog?ical protection, and it is also one of the key issues that need to be solved for the sustainable use of land resources. With the development of spatial simulation and intelligent optimization technology, the theoretical basis and methodological system of land-use optimization are constantly updated. Based on bibliometrics analysis, this paper systematically summarized the driving theories and methodology of land-use optimal allocation at home and abroad, focused on the application of spatial simulation models and intelligent optimization models in land-use optimization problems, discussed and prospected the challenges and the future development of optimal land-use allocation, and put forward that: The coupling drive of natural and human processes, spatial collaboration of multiple models, embedding big data knowledge mining methods, and the support of digital twin technology, should be the research direction of the next stage in the field of optimal land-use allocation.
