摘要
根据温县2001 ～2011年温度、光照、降水等气象资料和当地土壤类型等数据,采用1∶25万河南省基础地理数据,运用ArcGIS技术将1∶25万等高数据转化成数字地形模型;在此基础上进行定量分类研究,采用克里金方法将各要素进行空间插值,得到各要素的空间分布图;利用层次分析法来评价各因子的权重,确定焦作怀山药精细化气候区划分级指标.基于ArcGIS软件对焦作市怀山药种植区气候适宜性进行空间分析,得出焦作全区沿黄河一带的温县、武陟大部分地区及沁阳、孟州的部分地区为怀山药适宜种植区,也是怀山药的主要产区.
According to the temperature,light,precipitation and other eteorological data as well as the local soil type data of Wenxian from 2001 to 2011,adopt 1∶250 000 basic geographic data of Henan Province and transform 1∶250 000 data to digital terrain model by ArcGIS technology.On this basis,do quantitative classification research and use Kriging Interpolation Method to do spatial interpolation,then get spatial distribution of each factors.The index of the precise comprehensive suitable planting area division for Huaiqing yam was established by using analytic hierarchy process to evaluate the weight of each factor.Suitable climate of Huaiqing yam growing areas of Jiaozuo City was analyzed based on ArcGIS software in order to get that the most areas of Wenxian,Wuzhi along and a part areas of Qinyang,Mengzhou is the suitable planting area of Huaiqing yam,also the main producing areas of Huaiqing yam.
