基于生态位与约束CA的土地资源优化配置模型研究——以武汉市黄陂区为例

土地资源优化配置一直是土地科学的核心问题之一。传统的土地资源优化配置模型主要关注土地利用的经济属性而忽略土地利用行为的生态环境效应．已不适应可持续发展的要求;并且在优化内容上都是对土地资源数量结构的优化。忽视了土地资源空间布局优化．近几年很多学者通过与相关模型算法的集成形成的优化模型从一定程度上对数量结构优化模型进行了改造。实现了社会、生态、经济三效益的优化配置目标。但将土地资源数量结构优化与空间布局优化系统研究的模型却非常少见。本文运用生态位模型对土地资源数量结构进行优化进而将数量优化结果作为CA模拟的约束条件对空间布局进行优化．实现了土地资源数量结构优化与空间布局优化的统一。

Research on Optimal Allocation Model of Land Resource Based on Niche and CA:the Case of Huangpi

Land resource optimal allocation has always been one of the most challenging issues in land science field. The classical methodologies and theories of land resource allocation optimization emphasized on the economic benefit but lose sight of the effects of environment and resource, which has breached the sustainable development. Moreover, optimal allocation emphasized on the quantitative structure optimal and ignore the spatial configuration optimal. In recent years, many researchers mentioned some model-integration, which realized the social, zoological and economic benefits. But nearly nobody can construct the compasitive model which can combine the quantitative structure optimal with the spatial configuration optimal. This paper uses niche model to optimize the land quantitative structure and simulate the spatial configuration based on CA.
