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[Pseudostellaria heterophylla (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18 114.55 hm2,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2 475.92、6 440.69 hm2,分别占全县适宜茶叶种植面积的13.67%、35.55%。高度适宜区主要分布在牛大场镇、城关镇、白垛乡,其中,牛大场镇高度适宜种植太子参耕地面积为1 292 hm2,占全县高度适宜种植太子参耕地面积的52.2%。关键词:GIS;地统计学;太子参[Pseudostellaria heterophylla (Miq.)

Abstract: Based on the statistical method of GIS Technology, we conducted a research into the environmental adaptability of radix Pseudostellaria heterophylla (Miq.) Pax in complex geographical environment. Radix P. heterophylla (Miq.) Pax grown in Shibing of Guizhou Province as an example, twelve evaluation factors are chosen to evaluate the suitability to grow of radix P. heterophylla(Miq.) comprehensively,and they are effective accumulated temperature,annual rainfall,elevation,gradient,slope direction,soil pH value,soil organic matter,alkali-hydrolysable nitrogen,available phosphorus,available potassium, guarantee rate of drainage and traffic access degree which influence the quality of radix P. heterophylla (Miq.)’s grown. The results indicate that the area for planting Radix P. heterophylla(Miq.) is 18 114.55 hm2 in Shibing County, which accounts for 76.75% of the county’s cultivated area. For the total planting area, the acreage of highly suitable and generally suitable for planting are 2 475.92 hm2 and 6 440.69 hm2,respectively,while correspondingly,the tea crop area of the whole county they occupied are 13.67% and 35.55%. The highly suitable areas mainly distribute at Niudachang town,Chengguan town, and Baidu town. Among these,Niudachang town takes up 1 292 hm2 of the cultivated area accounting for 52.2% that of the whole country.

Key words: GIS, geostatistic, Pseudostellaria heterophylla (Miq.) Pax, suitability evaluation
