摘　　要：运用GIS方法和Huff模型,从供需角度出发,以分析、评估洛阳市现状绿地系统为基础,提出洛阳市绿地系统优化设计的措施和方案。具体做法是:依绿地的位置、大小、形状等要素判定其供应能力,结合居民点的空间分布及城市内部的道路网络系统,计算绿地和居民点之间的吸引力数值,深入研究绿地系统的通达性、空间分布及其服务供应能力与居民需求的关系;依据模型的分析结果,对洛阳市绿地系统进行优化设计,并运用Huff模型检验优化实施的效果,结果表明,优化后的洛阳市绿地系统的通达性、供应能力均得到了显著改善。研究表明GIS技术和Huff模型对规划实践中城市绿地系统的分析、优化非常有效。Using GIS and Huff model this paper presents the measures and schemes of optimizing the green space system by examining and evaluating the current green space of Luoyang.The method is to judge the supply ability of the green space according to its location,scale and form and calculate the absorption value between the green space and residential areas;then study the accessibility,distribution,and service ability of the green space with the demands of residents.It makes the optimization design of green space in Luoyang and then tests the effect of the optimization by Huff model.The results shows that the accessibility and supply ability of optimized green space have been great improved.The research indicates that the GIS technique and Huff model is useful to the analysis and optimization of urban green space in the planning practices.
