摘要
为了评估城市土地用作建设用地的生态适宜程度,以南宁市为例,识别市域内可用于进行城市建设的土地资源和生态敏感、脆弱、必须重点保护的区域。应用了生态适宜性评价方法,采用A rcM ap空间分析软件,综合考虑了水域、保护区、用地现状、地形地貌、工程地质等多项因子,并对不同因子赋予不同的权重进行叠加得到适宜性评价,为合理有效地安排土地资源的用途提供了重要依据。从保护城市生态环境的角度为城市的土地利用提出建议,为城市规划提供有益尝试和补充。
The ecological effects of construction projects must be evaluated to determine the appropriateness of using urban land for construction. Using Nanning city as an example, this study evaluates the ecological effects of using various plots of land for construction to identify areas which are suitable for construction or are sensitive and fragile. The ArcMap software was used with different weights given for the many factors, such as wet lands, land use plans, topography, engineering geology, and conservation areas. The evaluation shows how urban land use can be planned to protect the urban ecological environment in integrated urban planning.
