四川省小檗属植物物种资源及其分布规律研究

Geographical distribution of medicinal plants Arisaema in Sichuan

经调查研究结果表明，四川小檗属植物共有４０种、５变种．其中７种２变种为四川新分布记录，四川特有植物２种，首次提出四川优势资源植物７种１变种．分析讨论了水平分布与垂直分布规律．水平分布可划归５个自然植被区：川东盆地及盆周山地常绿阔叶林区，川西南山地常绿阔叶林区，川西高山峡谷针叶林区，川西高原针叶林、灌丛、草甸区，川西北高原、高山灌丛、草甸区；垂直分布范围为海拔５００～４０００ｍ，最适生长海拔高度１０００～３０００ｍ．并对资源进行了综合评估，提出了开发利用的有效途径．

By investigation and identification,there are 31 medicinal Arisaema plants in Sichuan (including variety).Among them,2 new recorded species,eg, A sikokinaum var henryanum and A sikokinaum is found in Sichuan for the time.The geographical ditribution in Sichuan,distribution regularity,distribution characteristic and the interrealtionship between distribution and climatic regionalizaton of the medicinal Arisaema plants are mainly discussed.
