摘要
在野外调查和数据收集的基础上,结合TCMGIS系统,对云南重楼ParispolyphyllaSmithvar.yunnanensis(Franch.)Hand.-Mazz.的产地适宜区进行分析与评价,并对生产区划进行了初探。研究结果表明云南重楼适生区域主要集中在西南地区云南、贵州、广西、四川等省(区),其潜在分布区大于目前的实际产区。鉴于云南重楼的生物学特性和生产实际,宜在适生区内开展以野生抚育为重点的人工规模化种植,本研究为云南重楼资源保护和可持续利用提供科学依据。
Paris polyphylla Smith var. yunnanensis （Franch.） Hand.-Mazz. is an important Chinese medicinal herb. Its wild resources have been extremely declined due to overharvesting. This research applied Traditional Chinese Medicine Geographic Information System （TCMGIS） to estimate the potential distribution of P. polyphylla var. yunnanensis with the climate, geographic and soil databases. Based on the field survey, specimens reference and literature investigation, we analyzed ecological factors and appropriate area of P. polyphylla Smith var. yunnanensis by Traditional Chinese Medicine Geographic Information System （TCMGIS）. The appropriate district of P. polyphylla var. yunnanensis mainly distributes the Yunnan-Guizhou Plateau, the Hengduan Mountain and the Ailao Mountain. We also determined the comprehensive ecological factors appropriated for its growth. The results are useful for development of P. polyphylla var. yunnanensis transplanting and cultivation.
