摘　　要：为了减少黔东南州种植生产太子参在选址时的盲目性,本文根据在贵州省施秉县牛大场镇种植基地观测的太子参生育特性资料,分析得到当地种植太子参的适宜性气候指标;利用黔东南州16个县市气象观测站的资料,利用经度、纬度以及海拔高度构建了各气候指标的地理分布模型,计算黔东南州204个乡镇与太子参生产密切相关的6个气候指标值;选用欧几里德(Euc lid)贴近度法实现模糊多目标最优选择,计算黔东南州204个乡镇的贴近度,进行黔东南州太子参气候适宜性分区。结果表明,黔东南州中部以西、以北地区的气候条件大都适宜种植太子参,可实现太子参的规模化、集约型生产;黔东南州中部以东、以南地区由于受高温和积涝的影响,要根据当地的实际气候条件,因地制宜地适当种植,不宜大规模发展。In order to reduce the blindness of the Radix Pseudostellariae （Pseudostellaria heterophylla Pax ex Pax et Hoffm. ） growing in the Southeast Guizhou Prefecture of Guizhou Province,the climatic indexes for the suitability of the Radix Pseudostellariae growing were gained, based on the data of the Radix Pseudostellariae growth and development observed in Niudachang town of Shibing County in Guizhou Province. The geographic distribution models of the climatic indexes were designed based on the meteorological data of the sixteen meteorological stations in the Southeast Guizhou Prefecture of Guizhou Province, by using statistical and regression analysis methods for the climatic index, longitude and latitude. The six climatic indexes, which were closely related to the Radix Pseudostellariae growing, were calculated in 204 villages and towns in the Southeast Guizhou Prefecture of Guizhou Province. According to the Climatic and ecological suitability of the Radix Pseudostellariae growing, which was made by choosing the Euclidean distance to realize the optimal fuzzy multi - objectives, the suitable growing areas for the Radix Pseudostellariae growing were divided. The result showed that the mid - west and mid - north parts of the Southeast Guizhou Prefecture were the suitable areas for the Radix Pseudostellariae growing, where the Radix Pseudostellariae could be intensively grown on a large scale. In the mid - east and mid -south parts of the Southeast Guizhou Prefecture, due to the adverse impacts of the high temperature and waterlogging, the Radix Pseudostellariae could not be grown on a large scale.
