土地利用总体规划指标时空分配

    Spatio-temporal allocation of general land-use planning index

    • 摘要: 土地利用总体规划的一个重要任务是定量、定时、定位地落实各种用地指标。为了合理确定土地利用规划总体目标以及阶段性目标,规划者不仅需要了解不同的社会经济发展方案对土地利用的不同需求及其时间变化特点,还需要了解其空间特征,以便定位地落实规划指标,实现土地利用优化配置。但已有研究中对土地利用规划指标时空分配的研究还较少,影响规划的编制和科学管理。该文以济南市长清区为研究对象,在借助系统动力学模型进行规划数量指标定量时间分配的基础上,利用GIS和CLUE-S模型,选择多个主控参数和影响因子进行试验研究,并定位地进行了多个方案的模拟,实现了规划指标分配时间模型和空间模型的融合并取得成功,提高了土地利用情景分析的可靠性,可为理解土地利用系统的复杂性和动态性提供帮助,并对土地利用总体规划编制辅助决策具有支撑作用。

       

      Abstract: One of the key tasks in general land-use planning is to allocate land use quantificationally on temporal scale and spatially in specific location. In order to achieve this goal, planners need to have an idea about the quantitative land demands in different development scenarios, and temporal and spatial characteristics of each planning which could assist them carry out the plan spatially and optimize the local land use. However, there is little research on the spatio-temporal allocation of general land-use planning index. To address this issue, this study coupled GIS, system dynamic model and CLUE-S model, and applied it to Changqing District, Jin’an City, Shandong Province, China. The results showed that the coupled model took the advantages of system dynamic model in scenario analysis and temporal simulation of local land use, and CLUE-S in spatial allocation of local land use. The model could provide the necessary information for planners and decision-makers, and a successful paradigm to land-use planning index in the angle of spatio-temporal combination.
