A Spatial Model of Urban Land Sustainable Use
城市土地可持续利用的空间布局建模

This paper presents an optimization model of urban land sustainable use planning, and this model has been implemented in the project of master planning at the Guilin city. In this paper, a modeling framework is proposed according to the demand of urban sustainable development. Then, transportation impact assessment model, spatial income equity assessment model, air quality assessment model and water quality assessment model of the Lijiang basin are established respectively. Considering assessment results of these assessment models, the objective of the optimization model is well elaborated. Finally, constraint conditions of the optimization model are presented.
