土地资源优化配置与区域公路网建设规模

为了优化土地利用结构、科学配置交通用地规模,为区域公路网规划提供可靠依据,在分析交通发展与土地利用平衡机理的基础上,建立了以土地利用效益系数为目标函数,以土地资源、社会需求和生态环境等为约束条件的土地资源优化配置理论模型,并以陕西关中地区土地利用为例,设置了16个变量,建立了土地资源优化配置模型,系统分析了土地利用优化方案和交通用地合理规模,为科学配置土地资源、确定区域公路网建设规模以及进行区域公路网规划提供了建设性的参考意见。

Optimized allocation for land resources and construction scales for regional highway network

In order to optimize the regional land-use structure, allocate transportation land-use scale scientifically, and provide reliable basis for regional highway network planning, the paper, on the basis of the balanced mechanism between transportation development and land use, establishes the function aiming at high beneficial coefficient of land use and a theoretical model for optimized allocation of land resources in consideration of land resources, social demand and biological environment. The authors take the examples of land use in Guanzhong area in Shaanxi Province, set up 16 variables equations and create a model for optimized allocation of land resources. Through scientific analysis for the optimized plan and proper scale of the development, the authors offer some constructive suggestions for the scientific allocation of land resources, proper scale of highway network construction and good planning work of the regional highway network.
