基于GIS的湖北省核桃良种基地空间布局研究

Research of Spatial Layout of Walnut Seed Breeding Base in Hubei Province Based on GIS

该研究在传统湖北省核桃良种基地规划布局的基础上,引入遥感技术、层次分析法和地理信息系统技术。湖北省核桃良种基地规划布局分成5个步骤进行,这5个步骤分别是:评价指标选取、指标权重确定、评价体系构建、评价因素叠加分析、评价结果分析。结果显示兴山县、房县、秭归县、郧西县和随县适宜建立国家级核桃良种基地。

On the basis of planning and layout of traditional walnut seed breeding base in Hubei Province, introducing remote sensing technol-ogy, AHP method and geographic information system, the planning and layout of Hubei Province walnut seed breeding base includes 5 steps： evaluation index selection, index weight determination, evaluation system construction, evaluation factors overlay analysis, evaluation results analysis. The results showed that Xingshan County, Fang County, Zigui County, Yunxi County and Sui County are appropriate to build nation-al walnut seed breeding base.
