摘  要:
针对云南省低丘缓坡土地特征,引导低丘缓坡土地进行城镇建设开发,构建低丘缓坡用地适宜性评价体系。首先,通过评价因子的"弹性/刚性"性质的界定与处理,确保评价的科学性与准确性;然后运用ArcGIS进行单因子评价以及叠加综合分析,生成适宜性评价图;最后通过综合考虑用地成本等现实因素修正评价成果,确保评价成果的科学合理性。并以云南省宾川县为例,探讨了评价体系的实际应用。应用结果表明,这套评价体系对于低丘缓坡土地的开发建设具有针对性强、评价结果较合理的特点。

摘  要:
An index system for the evaluation of land suitability for construction was presented to properly guide the urban construction and development of low-hilly and slow-sloping land resources in Yunnan Province through describing the environment characters. Firstly,a scientific security threshold was set by using"optional / unique"factor screening. Furthermore,through using the spatial analysis functions of ArcGIS, a map of suitability assessment of low-hilly and slow-sloping land resources was generated. Finally,a reasonable economy was framed by continuously extending and revising the assessment unit. Taking Binchuan in Yunnan Province as an example,the proposed system was applied to assess the suitability of low-hilly and slow-sloping land resources. The application results showed that the index system is more pertinent and enhance the rationality of the land use assessment.
