1、基于地统计学与GIS的施秉太子参种植适宜性评价摘要:基于GIS技术中地统计学方法对复杂地理环境下太子参[Pseudostellariaheterophylla(Miq.)Pax]产地环境适宜性评价进行研究,以贵州省施秉县太子参种植为例,选取影响优质太子参种植的年有效积温、年均降水量、海拔、坡度、坡向、土壤pH、土壤有机质、碱解氮、有效磷、速效钾、排灌保证率、交通通达度等12个评价因子,对太子参适宜性种植进行综合评价。结果表明,施秉县适宜太子参种植的面积为18114.55hm2,占全县耕地总面积的76.75%,其中高度适宜区和适宜区面积分别为2475.92、6
2、440.69hm2,分别占全县适宜茶叶种植面积的13.67%、35.55%O高度适宜区主要分布在牛大场镇、城镇、白垛乡,其中,牛大场镇高度适宜种植太子参耕地面积为1292hm2,占全县高度适宜种植太子参耕地面积的52.2%o关键词:GIS;地统计学;太子参[Pseudostellariaheterophylla(Miq.)Pax];适宜性评价中图分类号:R282文献标识码:A文章编号:0439-8114(2018)17-0037-05DOI:10.14088/j.cnki.issn0439-8114.2018.17.009开放科学(资源服务)标识码(OSID
