城市土地可持续利用的空间布局建模

A Spatial Model of Urban Land Sustainable Use

提出了一种城市土地可持续利用规划模型，该模型已在桂林市的总体规划中得以实施． 首先，根据城市可持续发展的要求，提出了建模的基本框架． 然后，分别建立了产业和人口布局的交通影响评价模型、空间收入公平性评价模型、大气环境质量评价模型和流域河网水质评价模型，并以这些评价模型的评价结果确定了城市土地可持续利用规划模型的优化目标． 最后给出了模型的约束条件．

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.
