摘  要:
建设用地适宜性评价是进行土地资源空间分析及优化土地配置的基础。根据四川省广安区丘陵资源丰富和建设用地需求量大的实际情况,研究基于GIS平台,综合选取以"自然-社会-经济"为框架的10个评价指标构建评价指标体系,对广安区低丘缓坡土地资源进行建设用地适宜性评价。结果表明,广安区低丘缓坡土地资源丰富,以适宜进行建设用地开发利用为主的占整个低丘缓坡资源的73.64%,其主要分布在区内的东北部、中部和西南部。

摘  要:
Evaluating the suitability of construction lands is the basis of spatial analysis and optimization of the allocation of land resources. According to the riched hilly resources and the great demand on construction lands in Guangan county, three classes and ten indicators of nature, society and economy were selected to build the suitability evaluation index system for the study area based on the support of GIS. The suitability of construction lands in low-slope hilly region was evaluated. The results showed that the low-slope hilly resources were rich in Guangan county. The suitable lands accounting for 73.64% of all resources in low-slope hilly region were suitable for the development and utilization of construction land and mainly distributed in northeast, central and southwest areas.
