Abstract: Land resource is one of the irreplaceable resources that human beings rely on. It is not only the main component of our environment, but also the carrier of other natural and social resources. Based on an overview of the worldwide research background for optimization of land use structure, the authors analyze the logistic framework of the optimal procedure and compare various kinds of relevant models. As a result, advantages and limitations in applications of the models are revealed. Meanwhile, significance of multi-objective optimal model in land use structure optimization application and scarce of land use spatial structure optimization are indicated.

摘要： 土地是人类生存和发展且不可替代的、短期内不可再生的自然环境资源，它既是环境的重要组分，又是其他自然环境资源和社会环境资源的载体。在对全球土地利用结构优化研究背景进行回顾的基础上，系统分析了土地利用结构优化过程的逻辑体系、土地利用数量结构与空间结构的优化决策模型，比较了这些模型在应用上的优点与局限性，指出多目标优化模型在土地利用结构优化应用中的实践意义与土地利用空间格局优化研究匮乏的问题。
