摘要: 城市绿地适宜性分析是进行城市绿地空间布局的必要前提。以沈阳市三环作为研究对象,在现状调研以及基础资料整理的基础上,引入多因素评价的方法,选取绿地适宜性分析的评价因子,采用层次分析法和成对比较法相结合来确定影响因子的权重,通过ArcGIS的空间分析模块对沈阳市城市绿地建设用地进行评价,识别区域内需要进行绿地建设的土地资源,以确定沈阳城市绿地空间布局及发展方向。结果表明:最适宜用地占11.1%,适宜用地占19.2%,基本适宜用地占23.3%,不适宜用地占29.5%,不可用地占16.5%,并提出构建沈阳城市风道、城市组团绿地、绿地生态网络等绿地空间布局的建议,为城市绿地系统规划提供新的思路。

Abstract: Land suitability analysis is the necessary premise for spatial distribution planning of urban green space. Based on the status investigation and statistical data, and by using multi-factors evaluation method, this paper evaluated the land suitability of green space in Shenyang City. The weights of affecting factors were decided by analytic hierarchy process (AHP) and pair-wise comparison, the suitable area for green space construction was analyzed based on the spatial analysis module in ArcGIS, and the identified land resource for green space construction was determined for the green space system planning and development direction in Shenyang in the future. In the City, the most suitable area for urban green space construction took 11.1%, suitable area took 19.2%, basically suitable area took 23.3%, unsuitable area took 29.5%, and unavailable area took 16.5%. According to the results, suggestions were provided on the spatial distribution of the construction of urban ventilation, urban group green space, and urban green space ecological network to highlight the urban green space system planning of Shenyang.
