摘要: 结合地理信息系统(GIS)与多目标区位配置模型(LA),综合考虑4个相对独立的目标因子(人口密度等级、空气污染等级、城市热岛效应等级、土地利用格局)对沈阳市三环内城市公园进行优化选址,并将优化结果与公园现状空间分布进行比较,以评价城市公园空间布局的合理性.结果表明: 与其他因子相比,空气污染因子对研究区城市绿地的选址具有重要影响.与单目标因子相比,多目标综合加权分析的结果能够合理地为城市绿地提供优化的空间选址.GIS与LA相结合的方法为城市绿地的空间优化提供了新思路.

Abstract: Based on geographic information system(GIS)technology and multi-objective location-allocation (LA) model, and in considering of four relatively independent objective factors (population density level, air pollution level, urban heat island effect level, and urban land use pattern), an optimized location selection for the urban parks within the Third Ring of Shenyang was conducted, and the selection results were compared with the spatial distribution of existing parks, aimed to evaluate the rationality of the spatial distribution of urban green spaces. In the location selection of urban green spaces in the study area, the factor air pollution was most important, and, compared with single objective factor, the weighted analysis results of multi-objective factors could  provide optimized spatial location selection of new urban green spaces. The combination of GIS technology with LA model would be a new approach for the spatial optimizing of urban green spaces.
