摘要
目的对区域每一点的适居性进行综合评价。方法采用AHP法对因子赋权。结果首先构建了区域适居性评价因子体系,接着利用图文数据源,在地理信息系统空间分析模块的支持下,通过单因子空间分析、布尔逻辑运算和复合叠置分析对区域适居性进行综合评价。结论运用GIS空间分析技术能实现多数据源处理、多指标叠合分析、多维度显示,这些功能为适居性评价提供了科学、客观、高效、直观的方法支持,今后应进一步提高评价的可靠性。
Aim To evaluate the habitability of every spot of region. Methods Giving every facfor a weight by AHP. Results Firstly, factor system of regional habitability evaluation is built up. Secondly, with text and figure data, by spatial analyzing module of GIS, the regional habitability is comprehensively evaluated via to single factor spatial analyzing, bull logical calculation and over lapping analynzing. Conclusion The processing of muhresourse data, overlay analysis of muhfactor and exporting of muhdemension provide objective and effective methods for regional habitability evaluation by GIS spatial analysis, we should improve the dependability appraised further in the future.
