基于本体与遗传算法的土地利用空间布局方法

Spatial Allocation of Land Use Based-on Ontology and Genetic Algorithm

土地利用空间布局是一个需要满足多种目标与约束的空间优化配置问题,现有的方法难以将各种目标与约束合理地纳入统一框架,实现结构调整与布局优化的一体化土地规划。本文通过构建土地利用规划本体知识库,有效地纳入专家知识与领域规则,并将本体知识库与遗传算法相结合,创建了结构调整与布局优化一体化的土地利用空间布局方法。将方法应用于福建省武平县新一轮土地利用总体规划,结果表明本文所提出的土地利用空间布局方法能很好地辅助开展土地利用规划,有效地增强土地规划过程的科学性与自动化水平。

Spatial allocation of land use is a spatial optimization process with a variety of objectives and constraints.It is challenging to carry out both the adjustment of land use structure and Land use allocation with spatial optimization stimulatingly.To solve this problem,this paper introduce the expert knowledge and domain rules into the framework of land use planning based on knowledge ontology and genetic algorithm.This new method is applied in Wuping county,Fujian province.Results demonstrate that this method is very efficient in the process of land use planning and greatly improve the level of automatic planning.
