| 摘 要： | 在总结分析国内外各种农作物土宜工作及其评价方法的基础上,以将森林资源二类调查数据、DEM、气候气象数据等作为数据源,采用主成分分析法约简山核桃适生环境的评价因子,得到关键因子集;结合层次分析法、模糊数学隶属函数建立山核桃适生环境综合评价模型,为山核桃的引种、扩种和区划提供理论依据和技术支持。

| Abstract: | On the basis of analyzing and summarizing variety of crops land suitability and its evaluation method at home and abroad,forest resource inventory second-class data,DEM,climate and weather data were used as data sources.Using principal component analysis,the evaluation factors of the suitable environmental of Carya cathayensis Sarg.were reduced and Key factors set was gotten.Combined with analytic hierarchy process(AHP)and membership function in fuzzy mathematics,the comprehensive evaluation model of suitab... |
